IRI: http://vocab.nerc.ac.uk/collection/L05/current/CHRP/
Chirp systems emit a 'swept-frequency signal', meaning that the transmitted signal is emitted over a period of time and over a set range of frequencies. This repeatable (transmitted) waveform can be varied in terms of pulse length, frequency bandwidth, and phase/amplitude. A matched filter, or correlation process, collapses the swept frequency modulated (FM) received signal into a pulse of short duration, maximizing the signal-to-noise-ratio. The reflected signal is received by a tuned transducer array that generates the outgoing acoustic energy. Chirps operate within a range of 400Hz - 24 kHz and are used for the first 20-30 metres of unconsolidated sediments.

Any instrument that may be considered the underwater acoustic equivalent of an optical video camera belongs in this category.
IRI: http://vocab.nerc.ac.uk/collection/L05/current/MPIS/
Active sonar systems that provide a cross-sectional profile of a target area. These instruments typically emit a series of acoustic pulses in a beam pattern like a spot or pencil beam and the peak echo return is recorded. They provide a digitised version of echo returns as opposed to multicoloured images by imaging sonars. They are generally deployed on survey vessels pointing the transducer down towards the target. Applications of profiling sonars include cross-sectional profiling in pipeline and trench survey, bottom profiles, and surveying of underwater cave systems or manmade structures like road and rail bridge foundations. Examples of this type of system are Tritech Super SeaKing DFP Profiler and Imagenex 881A Profiling Sonar Head.

A British Antarctic Survey-built version of the Multiple Opening and Closing Net with an Environmental Sensing System (MOCNESS) originally designed by Wiebe et al. (1976) for capturing zooplankton. This version consists of nine nets, which can be towed to a maximum depth of 1000 m. A live data stream allows an operator on the ship to close a net, thus triggering the opening of the next one. The first net is open when the system goes in the water; when the maximum depth is reached, the operator triggers it to close, thus automatically prompting the next one to open. This mode of operation is repeated until all nets have collected samples. This system allows for accurate control over timing and location of samples, which are collected sequentially through the nine nets. The frame also carries a current meter and a CTD system.

A non-membrane dissolved oxygen sensor for marine applications. The sensor uses a platinum microelectrode and a counter electrode (thus far composed of copper). A measurement potential is applied to the microelectrode relative to a counter electrode, reducing the dissolved oxygen in the water and generating a current through the microelectrode proportional to the number of oxygen molecules at that electrode. The sensor was first used in 2000 and development is ongoing. Early versions of the instrument applied the measurement potential for up to 30 seconds, with sampling starting approximately one second after the potential was applied. The sensor response to oxygen remained almost constant for a given concentration and data could be sampled at frequencies exceeding 1 Hz. To reduce noise generated by sensitivity to flow fluctuations a mesoporous layer was used to increase the surface area of the microelectrode, but this proved unstable and was replaced by a stop-flow system which pumped water in to a very small chamber, with measurements being taken while the water was still. This significantly improved results but the sensor was still affected by small convection currents. The current version of the sensor only applies the measurement potential for a few 10s of milliseconds and data are collected at approximately 1 Hz in an attempt to minimise the effects of convection currents. The latest development is a very small sensor head containing an array of microelectrodes (currently an array of five) that work together. The counter electrode consists of silver or silver chloride. This is currently undergoing trials and is yet to be deployed on a CTD profiler.

A circular disk, typically 20cm in diameter, used to measure water transparency. For marine applications, the disk is usually entirely white, while for limnological studies it is common to use one with alternating black and white quadrants. The reasons for this may be historical rather thah theoretical. A black Secchi disk has recently been developed for use in shallow rivers and streams. The disk is lowered slowly into the water on a pole or line until it can no longer be seen by the observer. The depth of disappearance provides an estimate of the transparency of the water, although any reading is affected by the observer's eyesight and ambient light conditions.

The Sea-viewing Wide Field-of-view Sensor (SeaWiFS) is an optical scanner designed to provide quantitative ocean colour data for derivation of global ocean bio-optical properties. Incoming radiation is collected by a folded telescope and reflected onto a rotating half-angle mirror. The collected radiation is relayed through dichroic beam splitters to separate it into four wavelength intervals, each of which is directed through two spectral bandpass filters to further separate it into the eight SeaWiFS spectral bands, imaged onto one of four detectors and amplified for processing. The scanning telescope rotates at a rate of six revolutions per second, and a scanner tilt mechanism enables the instrument to tilt from -20 degrees to +20 degrees to avoid sun glint from the sea surface. The SeaWiFS instrument has a spatial resolution of 1.6 mrads, and measures radiation in eight optical bands: 402-422nm; 433-453nm; 480-500nm; 500-520nm; 545-565nm; 660-680nm; 745-785nm; 845-885nm.

The Moderate Resolution Imaging Spectroradiometer (MODIS) is an optical spectroradiometer that acquires photo-radometric data of terrestrial, oceanic and lower atmospheric environments for the study of global dynamics. Incoming radiation is directed by a continuously rotating double-sided scan mirror, scanning from -50 to +50 degrees. It directs radiation into a two-mirror off-axis afocal telescope. A dichroic beam splitter then splits the radiation into four optical objective and focal plane assemblies. There are separate assemblies for both near infrared (short and long-wave) and visible spectral bands. These are further split into 36 spectral bands ranging in wavelength from 0.4 to 14.4 micrometres. Bands 1-2 are imaged at a nominal spatial resolution of 250 m at nadir, with bands 3-7 at 500 m and the remaining bands (8-36) at 1 km. The MODIS instrument has a cross track scan rate of 20.3 rpm, and measures radiation in 36 optical bands (bands 1-19 are in nanometres and bands 20-36 are in micrometres): 620-670 nm; 841-876 nm; 459-479 nm; 545-565 nm; 1230-1250 nm; 1628-1652 nm; 2105-2155 nm; 405-420 nm; 438-448 nm; 483-493 nm; 526-536 nm; 546-556 nm; 662-672 nm; 673-683 nm; 743-753 nm; 862-877 nm; 890-920 nm; 931-941 nm; 915-965 nm; 3.660-3.840 micrometres; 3.929-3.989 micrometres; 3.929-3.989 micrometres; 4.020-4.080 micrometres; 4.433-4.498 micrometres; 4.482-4.549 micrometres; 1.360-1.390 micrometres; 6.535-6.895 micrometres; 7.175-7.475 micrometres; 8.400-8.700 micrometres; 9.580-9.880 micrometres; 10.780-11.280 micrometres; 13.185-13.485 micrometres; 13.485-13.785 micrometres; 13.785-14.085 micrometres; 14.085-14.385 micrometres.

The Microwave Radiation Imager (MWRI) is a conical-scanning microwave imaging radiometer designed to measure precipitation, soil moisture, vegetation, cloud liquid water and sea surface parameters such as wind. The MWRI gathers light through a ground-pointing telescope, whose scan mirror oscillates (1 cycle every 33 milliseconds) over an angular displacement of plus-or-minus 2.89 degrees that is perpendicular to the orbital track. Light reflected from the surface and atmosphere as gathered by this scan passes through an optical lens train, during which the beam is divided to pass through 4 bandpass filters that produce images in 4 spectral bands. The light from each filter then reaches a set of six electronic detectors (24 in total, 6 per spectral band) that subdivides the across-track scan into 6 parallel lines, each equivalent to a ground width of 79 m. The MWRI features 10 channels with five frequencies in the range 10.65-89 GHz. The nadir spatial resolution range varies from 15-85 km depending on frequency. The wavelengths of the four spectral bands are 0.5-0.6 micrometres, 0.6-0.7 micrometres, 0.7-0.8 micrometres and 0.8-1.1 micrometres. The instrument has a swath width of 1400 km and a scan rate of 35.3 scan/min, or 11.2 km/scan. Flown on FY-3. http://www.wmo-sat.info/oscar/instruments/view/350

The Operational Land Imager (OLI) is a high resolution optical imager designed for land and vegetation observation. It measures in the visible, near-infrared, and short-wave infrared spectrums over nine spectral bands. The OLI uses long detector arrays (of over 7000 detectors per spectral band) aligned across its focal plane to view across the swath. A four-mirror anastigmatic telescope focuses incident radiation onto the focal plane while providing a 15 degree field of view (FOV). Periodic sampling of the cross-track detectors as the observatory progresses along a ground track forms the multispectral digital images. The detectors are divided into 14 modules arranged in an alternating pattern along the centreline of the focal plane. The spectral differentiation is achieved by interference filters arranged in a butcher-block pattern over the detector arrays in each module. Silicon PIN (SiPIN) detectors collect the data for the visible and near-infrared spectral bands (bands 1 to 4 and 8) while Mercury-Cadmium-Telluride (MgCdTe) detectors are used for the shortwave infrared bands (bands 6, 7, and 9). The OLI has a swath width of 185 km and produces images with a 30 m multi-spectral spatial resolution. The wavelengths of the nine spectral bands are 0.433-0.453 micrometres, 0.450-0.515 micrometres, 0.525-0.600 micrometres, 0.630-0.680 micrometres, 0.845-0.885 micrometres, 1.560-1.660 micrometres, 2.100-2.300 micrometres, 0.500-0.680 micrometres and 1.360-1.390 micrometres. The OLI produced data calibrated to an uncertainty of less than 5 percent in terms of absolute, at-aperture spectral radiance and to an uncertainty of less than 3 percent in terms of top-of-atmosphere spectral reflectance for each of the spectral bands.

POLDER (Polarisation and Directionality of the Earth's Reflectances) is a passive optical imaging radiometer and polarimeter designed to observe solar radiation reflected by Earth's atmosphere, including studies of tropospheric aerosols, sea surface reflectance, bidirectional reflectance distribution function of land surfaces, and the Earth Radiation Budget. It measures surface reflectance in the visible and near-infrared bands. POLDER consists consists of a digital staring camera composed of a 274 x 242 pixel CCD (charged coupled device) detection array, wide field-of-view telecentric optics (plus-or-minus 51 degrees cross-track and plus-or-minus 43 degrees along-track) and of a rotating wheel carrying spectral and polarised filters of an optical subsystem and electronics subsystem. The optical subsystem consists of a telecentric lens, a filter wheel and a CCD array as a detector. The light is almost vertically incident on the filter wheel after the telecentric lens makes the optical correction. The CCD array (244 x 274 elements) can collect two-dimensionnal images. The filter wheel has 16 filters and is rotated so that 16-channel images are acquired per one rotation. The main functions of electronics subsystem are to process imagery (eg. A/D conversion), to handle telemetry/command for operation of the processed image and POLDER and to control the filter wheel, the electric power and the heat. POLDER measures radiation in nine spectral bands with wavelengths centred at 443.5 nanometres (nm), 490.9 nm, 563.8 nm, 669.9 nm, 762.9 nm, 762.7 nm, 863.7 nm, 907.1 nm and 1019.6 nm.

The Spinning Enhanced Visible and Infrared Imager (SEVIRI) is an optical imaging radiometer designed for cloud imaging and tracking, fog detection, measurement of the Earth-surface and cloud-top temperatures, and the tracking of ozone patterns. This enables analysis of the characteristics of atmospheric air masses to reconstruct a three-dimensional view of the atmosphere. The SEVIRI instrument is composed of a Telescope and Scan Assembly (TSA), a Focal Plane and Cooler Assembly (FPCA), and an Electronic Unit Assembly (EUA). SEVIRI has 12 channels; 8 in the infrared, 1 in the high resolution visible, 2 in the visible, and 1 in the near-infrared spectrums. The scanning mirror is used to move the instrument line-of-sight (LOS) in the south-north direction. The target radiance is collected by the telescope and focused onto the detectors. Channel separation is performed at telescope focal-plane level, by means of folding mirrors. A flip-flop type mechanism is periodically actuated to place the IR calibration reference source in the instrument's field of view. The image data are directly transferred from the Main Detection Unit (MDU) to the onboard data-handling subsystem. The Functional Control Unit (FCU) controls the SEVIRI functions and provides the telemetry and telecommand interfaces with the satellite.

The Scanning Multichannel Microwave Radiometer (SMMR) is a 5-frequency, 10-channel microwave radiometer designed for the creation of areal sea-ice climatologies for the Arctic and Antarctic. This involves measurements of sea surface temperatures, low altitude winds, water vapour and cloud liquid water content, sea ice extent, sea ice concentration, snow cover, snow moisture, rainfall rates, and differentiation of ice types. Six conventional Dicke-type radiometers are used. Those operating at the four longest wavelengths measure alternate polarisations during successive scans of the antenna; the others, at the shortest wavelength, operate continuously for each polarisation. A two-point reference signal system is used, consisting of an ambient RF termination and a horn antenna viewing deep space. A switching network of latching ferrite circulators selects the appropriate polarisation or calibration input for each radiometer. The SMMR also contains an antenna subsystem in which a 42 degree offset parabolic reflector focuses the received power into a single feedhorn covering the entire range of operating wavelengths, and provides coaxial antenna beams for all channels. The SMMR delivers orthogonally polarised antenna temperature data at five microwave wavelengths: 0.81, 1.36, 1.66, 2.8 and 4.54 cm, at frequencies of 6.63, 10.69, 18.0, 21.0, and 37.0 GHz.

The Special Sensor Microwave Imager (SSM/I) is a passive microwave radiometer that measures atmospheric, oceanic and terrestrial microwave brightness temperatures at 19.35, 22.2, 37.0, and 85.5 GHz, from which ocean surface wind speed, atmospheric water vapour, cloud liquid water and rain rate can be derived. The SSM/I consists of an offset parabolic reflector of dimensions 24 x 26 inches, fed by a corrugated, broad-band, seven-port horn antenna. The reflector and feed are mounted on a drum that contains the radiometers, digital data subsystem, mechanical scanning subsystem, and power subsystem. The reflector-feed-drum assembly is rotated about the axis of the drum by a coaxially mounted bearing and power transfer assembly (BAPTA). All data, commands, timing and telemetry signals, and power pass through the BAPTA on slip ring connectors to the rotating assembly. The absolute brightness temperature of the scene incident upon the antenna is received and spatially filtered by the antenna to produce an effective input signal or antenna temperature at the input of the feed horn antenna. The SSM/I has seven channels, four frequencies, and is orthogonally polarised. It rotates continuously about an axis parallel to the local spacecraft at 31.6 rpm and measures the upwelling scene brightness temperature over an angular range of 102.4 degrees at nadir. The active scene measurements lie +51.2 to -51.2 degrees about the forward (F10, F11) or aft (F8) direction. This results in a swath width of approximately 1400 kilometres. During each 1.9 second scan, 128 discrete uniformly spaced radiometric samples are taken at the two 85 GHz channels and, on alternate scans, 64 discrete samples are taken at the remaining lower frequency channels. The antenna beam intersects the Earth's surface at an incidence angle of 53.1 degrees.

The Special Sensor Microwave Imager Sounder (SSMI/S) is a passive microwave radiometer that is an enhanced version of the The Special Sensor Microwave Imager (SSM/I). It measures atmospheric, oceanic and terrestrial microwave brightness temperatures from 19 to 183 GHz, from which ocean surface wind speed, atmospheric water vapour, cloud liquid water and rain rate can be derived. The SSMI/S is an enhanced version of the SSM/I. It consists of an offset 24-inch parabolic reflector fed by a corrugated, broad-band, seven-port horn antenna. The reflector and feed are mounted on a drum that contains the radiometers, digital data subsystem, mechanical scanning subsystem, and power subsystem. The reflector-feed-drum assembly is rotated about the axis of the drum by a coaxially mounted bearing and power transfer assembly (BAPTA). All data, commands, timing and telemetry signals, and power pass through the BAPTA on slip ring connectors to the rotating assembly.The absolute brightness temperature of the scene incident upon the antenna is received and spatially filtered by the antenna to produce an effective input signal or antenna temperature at the input of the feed horn antenna. The feedhorn data are input to the receiver subsystem where frequency multiplexing occurs to produce 24 channels of data. The receiver outputs are converted to the video spectrum, digitized and formatted. The SSMI/S has 24 channels and eight frequencies. It measures the same frequencies and polarisations as the SSM/I, with the exception of the 85.5 GHz channel which has been replaced by a 91.655 GHz channel. A 183 GHz channel has also been added. The instrument rotates continuously about an axis parallel to the local spacecraft at 31.6 rpm and measures the upwelling scene brightness temperature over an angular range of 143.2 degrees at nadir. It has a swath width of approximately 1700 kilometres. Frequency multiplexing occurs as the main reflector is illuminated by six broadband corrugated feedhorns, grouping Channels 1-5; Channels 6, 7, 19-24; Channels 12-14; Channels 15-16; Channels 8-11; and Channels 17-18.

The Thermal And Near-infrared Sensor for Carbon Observation - Cloud and Aerosol Imager (TANSO-CAI) is one of two instruments that the Thermal And Near-infrared Sensor for Carbon Observation (TANSO) is composed of. It is a radiometer designed to measure aerosol spatial distribution and cloud coverage in the visible, ultraviolet and shortwave infrared spectrums. This information is primarily used to correct the effects of clouds and aerosols on the spectra obtained from the primary TANSO instrument, Thermal And Near-infrared Sensor for Carbon Observation - Fourier Transform Spectrometer (TANSO-FTS). TANSO-CAI has a continuous spatial coverage, wider field of view, and higher spatial resolution than TANSO-FTS in order to detect aerosol spatial distribution and cloud coverage. Using the multispectral bands, the spectral characteristics of the aerosol scattering can be retrieved together with optical thickness. In addition, the UV-band range observations provide the aerosol data over land. With the FTS spectra, imager data, and the retrieval algorithm to remove cloud and aerosol contamination, the column density of the gases can be retrieved with an accuracy of 1%. The TANSO-CAI instrument operates within four sepctral bands in the following wavelength ranges: 0.370-0.390 micrometres (band1); 0.664-0.684 micrometres (band 2); 0.860-0.880 micrometres (band 3); 1.56-1.65 micrometres (band 4). The instrument has a spatial resolution of 0.5 km at nadir for bands 1-3, and 1.5 km at band 4.

The Tropical Rainfall Measuring Mission's (TRMM) Microwave Imager (TMI) is a conical-scanning passive microwave radiometer designed to provide quantitative rainfall information over a wide swath width. It measures microwave energy emitted by the Earth and atmosphere to quantify the water vapour, cloud water, rainfall intensity and rainfall rates in the atmosphere. The TMI design is based on the SSM/I, detecting microwave energy in the form of of brightness temperatures from Earth's surface and atmosphere. It measures this at five separate frequencies. TMI consists of nine separate total-power radiometers, each simultaneously measuring the microwave emission coming from the Earth's surface with the intervening atmosphere. TMI employs an offset parabolic reflector (antenna aperture size of 61 cm) to collect the microwave radiation. The reflector focuses the radiation into two feedhorn. The reflector and feedhorns spin as a unit about an axis parallel to the S/X nadir direction. A cold-space mirror and a warm reference load are attached to the spin axis and do not rotate. The rotating feedhorns observe the fixed cold mirror and warm load once each scan for calibration purposes. The TMI measures radiation intensity at 10.7, 19.4, 21.3, 37 and 85.5 GHz. It has a resolution ranging from 7 km x 5 km to 63 km x 37 km depending on the frequency used, and a feedhorn-reflector rotation period of 1.9 s.

The WindStat Polarimetric Microwave Radiometer is a 22-channel microwave radiometer designed to measure the ocean surface wind vector from space, in addition to sea surface temperature, total precipitable water, integrated cloud liquid water, and rain rate over the ocean. WindSat is also used to measure soil moisture, sea ice and tropical cyclone structure. WindSat uses a 1.8 m offset reflector antenna fed by 11 dual-polarised feed horns. The antenna beams view the Earth at incidence angles ranging from 50 to 55 degrees. The feedhorns of each frequency channel trace out different arcs along the scan, therefore the Earth Incidence Angles (EIA) are different for each frequency band. The WindSat sensor takes observations during both the forward and aft looking scans. The 10.7, 18.7 and 37.0 GHz bands are fully polarimetric. Six principal polarisations are measured directly using three dual polarisation feeds at each of the polarimetric frequencies. The 6.8 and 23.8 GHz channels are dual-polarised as data at these frequencies are used for secondary parameters such as sea surface temperature and water vapour, which support the wind vector retrievals. WindSat operates in discrete bands at frequencies of 6.8, 10.7, 18.7, 23.8, and 37.0 GHz. The antenna rotates at 30 rpm. Measurements are made over a forward swath of 1400 km and an aft swath of 750 km. Flown on Coriolis. https://www.nrl.navy.mil/WindSat/Description.php

A passive optical imager with dual view composed of a 7-channel infra-red radiometer, designed to measure sea surface temperature, cloud attributes, as well as vegetation and sea-ice cover. The infra-red radiometer uses an along-track scanning telescope to focus incoming radiation from two views at different angles: one at nadir and one fore-looking at approximately 47 degrees.

The instrument carries an on-board visible calibration system. The AATSR is functionally identical to ATSR-2, but its structure is adapted to the Envisat platform. Moreover, AATSR has a larger telemetry bandwidth compared to ATSR-2, allowing it to collect and telemeter a greater amount of visible data.

A five-channel imaging radiometer designed to measure radiant and solar reflected energy from sampled areas of the earth, with the primary mission of determining cloud cover and characteristics, as well as water vapour features and horizontal wind. The Imager's optical system collects scene radiance, which is then separated into spectral channels by beam splitters. One of the bands captures the Earth's reflected radiation in the visible part of the electro-magnetic spectrum; the other four bands sense the Earth's emitted or infrared energy. The spectral energy is then directed to different visible and infrared sets of detectors, and converted into an electrical signal by each detector. The signal goes through amplification, filtration and digitalization before being sent to a ground station through a sensor data transmitter. The Imager uses a Cassegrain telescope in conjunction with a servo-driven, two-axis gimbaled mirror scan system to simultaneously sweep an 8 km north-to south swath along an east-to-west/west-to-east path at a rate of 20 degrees per second. The Imager collects at five bands of radiation wavelengths: (0.55 - 0.75) um, which is the visible band and has a spatial resolution of 1 km; (3.80 - 4.00) um, (6.50 - 7.00) um, (10.2 - 11.2) um and (11.5 - 12.4) um, which are the infrared bands, and have a spatial resolution of 4 km.

The V8 tag is particularly suited for monitoring of salmon smolt migrations, and can be used to track large numbers of fish over large areas. The V8 offers an alternative between the V7 and V9 tags due to its higher output power and greater detection range. V8 coded transmitters send acoustic pings at 69 kHz that are infrequent and random about an average delay. This ping train includes an ID number which permits identification of the specific tag. The V8 can be detected by all VEMCO 69 kHz receivers. There are two battery options, the 4L or 4H. To control the characteristics of the tags, users can choose from one to four programming steps: Status (ON/OFF), time interval, acoustic power level (L/H) and nominal delay.

A coded acoustic transmitter used to measure the activity of free-ranging fauna in nature, most commonly fish. The transmitter measures the 3D acceleration with depth of fauna moving within a reciever array as a vector quantity, i.e. it measures acceleration on 3 axes X, Y and Z, in metres per second squared. Other applications may include determination of swimming speed via tail beat acceleration, activity responses to changing oxygen, temperature and salinity, and detecting mortality through predation, seismic blasting, toxic spills, feeding events, spawning activity, nocturnal/diurnal activity or wave action. One of two modes of operation can be specified; an activity alogorithm or tailbeat algorithm. Coded transmitters send acoustic pings at 69 kHz that are infrequent and random about an average delay. This ping train includes an ID number which permits identification of the specific tag and sensor data. For dual sensor tags, there are two tag IDs. The V9 is also available as an accelerometer option only (V9A).

The VR2AR is a submersible acoustic receiver, combining an acoustic release with a VR2Tx (a VR2W receiver with a built in V16-like transmitter). It is used with Vemco coded transmitter tags placed on marine fauna to track their movements or behaviour. These detections are then received and stored by Vemco receivers, whose content are monitored by the VR2AR. The unit allows remote communication with all Vemco 69 kHz receivers while still deployed, and it can be retrieved via the built-in acoustic release. Deployed receivers can also be retrieved via the VR2AR, and their status monitored on demand via communication with a surface VR100 tracking receiver and transponding hydrophone. Receiver health, tilt angle, range, temperature, battery life and memory can be monitored in this way. The total number of detections stored by different receivers and specific transmitter tag IDs can also be monitored. An optional flotation collar is available to assist in location and retrieval of the VR2AR. It attaches below the receiver hydrophone ensuring there are no shadowing effects on the receiver. It has a maximum depth rating of 500m, battery life of approximately 14 months and 16 MB internal storage.

A British Antarctic Survey-built shipboard three-component magnetometer. The design of this instrument was based on the STCM described by Korenaga et al., 1995; however, BAS's version is simplified, it does not use a gyrocompass, and records heave, roll and pitch information using an Ashtech 3D GPS and TSS300 HRP attitude sensor. One of the principles of the STCM is to simultaneously measure the ship's attitude and the magnetic vector field, in order to remove the effect of the ship's motion. In order to obtain unbiased ambient geomagnetic field measurements, the ship's own magnetisation needs to be known. This is obtained by carrying out 'figure eight' manoeuvres at constant speed, during which unbiased ship's rolling data can be acquired.

An optical device that renders distant objects more distinct by enlarging their images on both retinas of the observer. They are used for observation of distant objects on the Earth's surface. Unlike telescopes, binoculars present two images from slightly different viewpoints, producing a merged view with an impression of depth for the observer. Reflected visible light is converged via two objective lenses to magnify the view, which is initially inverted. An erect (non-inverted) image is achieved either by an erecting lens or a prism. Porro prism binoculars use a pair of porro prisms in a Z configuration to erect the image, offering a bright image and good depth sensation. Roof prism binoculars are more compact as the objectives lenses are in line with the eyepieces, but produce images with reduced brightness. Very small instruments may be of the Galilean type, which yields an erect image using a positive objective lens and a negative eyepiece lens. Hand-held binoculars typically use objective lenses 25 to 50 mm in diameter with 7x to 10x eyepiece magnification, but this can vary.

A center-pivot sampler designed to sample unconsolidated sediments from soft ooze to hard-packed silts from deep lakes and near offshore. The sampler scoops a sediment sample from the top 10cm of the seabed. It brings up virtually un- disturbed, unwashed samples to the surface from any depth. Its specialty is sampling benthic organisms living at or immediately below the water/bottom interface and sediment containing a significant population of non-sessile forms. When the grab touches the bottom, inertia from a self-contained weight releases a catch and helical springs rotate the inner half cylinder by 180 degrees. After turning, the scoop remains closed by the residual torque of the scoop spring. Because the rotation of the bucket is very rapid, its shear strength is far greater than the sediment strength, thus cutting cleanly, particularly in soft clays, muds, silts and sands. Manufactured in 316 stainless steel with a sampling area of 0.042m sq. There is the option of adding a landing table.

The ISIIS was developed in collaboration between the University of Miami's Rosenstiel School of Atmospheric and Marine Science (RSMAS) and the subsea engineering company, Bellamare, LLC. Funding was provided by the National Science Foundation, NOAA, UNH Large Pelagics Center, and UM Maytag Chair of Ichthyology. ISIIS systems image organisms and particles in-situ as they swim or flow in between its two pods (fitted with a camera and illumination system). The instrument captures images of mostly undisturbed organisms, at a fine spatial and temporal resolution. ISIIS is an underwater imaging system for capturing in situ, real time images of marine zooplankton of relatively low abundance such as fish larvae and fragile gelatinous organisms. ISIIS imaging systems use industrial grade cameras. On towed sleds, they use a line-scan camera creating one single continuous image representing a real slice of the ocean. However, they can also be fitted with a classic area-scan camera if a system is to be used still (underwater monitoring station) or do slow vertical profiles. The ISIIS system utilizes a high-resolution line-scanning camera with a Light Emitting Diode (LED) light source, modified by plano-convex optics, to create a collimated light field to backlight a parcel of water. The imaged parcel of water passes between the forward portions of two streamlined pods (UW housings), and thereby remains unaffected by turbulence. The resulting very high-resolution image is of plankton in their natural position and orientation. When a sufficient volume of water is imaged this way, quantification of density and fine-scale distribution is possible. ISIIS is capable of imaging a maximum of 162 L of water per second (when flying at 5 knots) with a pixel resolution of 70 um, imaging particles from 1 mm to 13 cm in size.

The device can be used on towed bodies e.g. V-fin depressor, and SeaSoar (a towed undulating vehicle); Remotely Operated Vehicles (ROVs) e.g. JASON and SeaRover; Autonomous Underwater Vehicles (AUV) e.g. REMUS; and autonomous profiling moorings. A video camera mounted in one of the arms focuses on a point midway between the two arms. A strobe on the other arm illuminates the imaged volume and flashes 60 times per second, producing 60 images per second of the particles and plankton in the water. The images are then saved internally on a computer hard disk and later plotted. A CTD can also be mounted next to the VPR to collect basic physico-chemical parameters such as depth, temperature, and salinity at the same time as each video image. The VPR has a depth rating of 350 meters.

Submersible Digital Holographic Particle Imaging System for measurement of large, complex flocs, plankton, and other particles in water. It takes images at very short shutter times, scanning for a relatively large volume. The LISST-HOLO contains a red (658nm) laser that emits collimated light into the sample volume. The light is scattered by suspended particles. The scattered light then interferes with the unscattered portion of the beam. The resulting interference pattern is captured by an onboard camera. The image captured by the camera is known as a hologram. The hologram can be digitally reconstructed to produce an in-focus picture of all the particles in the sample volume. Information about the particles size, shape, and position can all be extracted from the hologram. Holograms are captured at 20Hz. The system has 237 GB of data memory.

An in situ fluorimeter designed to monitor concentrations of hydrocarbons (360nm) and Gelbstoff (440nm). The instrument may be mounted on a towed vehicle such as Chelsea Technologies Group's AQUAshuttle III, NvShuttle or SeaSoar, it can be deployed on buoys, on a mooring, or vertically in a profiling mode. The fluorimeter uses a pulsed light double beam technique. The pulsed technique allows virtually perfect discrimination to be achieved against "steady" ambient light signals since the light pulse is only two microseconds long, variations in ambient intensity due to wave glitter, etc. are considered "steady" by the high-speed processing circuits and are effectively rejected by the AQUAtracka. The double beam system allows the light intensity of the optical beam(X) returned from the specimen to be compared with the light intensity of the reference beam(Y) generated from the same pulsed light source. The outputs are then ratioed(X/Y) so that they are not affected by any variations in the flash lamp strength due to lamp ageing. The housing is constructed in titanium and the instrument is rated to 600m (option 6000m) and incorporates an optional ambient light baffling cowl. A fast response (300ms) platinum resistance Pt 100 Temperature Probe can also be included optionally. Using 360nm fluorescence the detection range is between 0.001 and 10 micrograms per litre of Carbazole. Using 440nm fluorescence the detection range is between 0.001 to 10 micrograms per litre Perylene. The operating temperature range of the instrument is -2 to +40 degrees Celsius.

The KC Pore-water pressing bench allows pore-water extraction of any kind of sediments, from sediments rich in organic material, to sandy sediments. Sediment cores are segmented and placed in the pressing house, which is closed by means of the handle on top of the house. An over-pressure is applied (fed-in) at the reduction valve and the valves of the houses in operation are opened. The resulting compression of the sediment matrix leads to expelling of the pore-water, which is sampled in containers beneath the pressing house. Operation in a glove bag prevents atmospheric contamination with, for example, oxygen, so anaerobic analysis of the pore-water is possible. The standard cylinders are made from black Polyoxymethylene (POM). However, the cylinders and all accessories are also available as AISI 316 stainless steel for special purposes. The pressing bench consists of 5 pressing houses, each 100 ml. They can hold a maximum sample diameter of 40 mm. The instrument has a maximum operating pressure of 4 bar (400 kPa).

The Environmental Characterization Optics, or ECO miniature combination scattering meter and fluorometer allows the user to measure backscattering at two wavelengths (470 and 740 nm) at 117 degrees and chlorophyll fluorescence within the same volume. The instrument is used to monitor chlorophyll concentration by directly measuring the amount of chlorophyll-a fluorescence emission from a given sample volume of water. Chlorophyll, when excited by the presence of an external light source, absorbs light in certain regions of the visible spectrum and re-emits a small portion of this light as fluorescence at longer wavelengths. The ECO uses two bright blue LEDs (centred at 455 nm and modulated at 1 kHz) to provide the excitation source. A blue interference filter is used to reject the small amount of red light emitted by the LEDs. The blue light from the sources enters the water volume at an angle of approximately 55-60 degrees with respect to the end face of the unit. Fluoresced light is received by a detector positioned where the acceptance angle forms a 117-degree intersection with the source beam. A red interference filter is used to discriminate against the scattered blue excitation light. The red fluorescence emitted is synchronously detected by a silicon photodiode. The ECO uses three LEDs (modulated at 1 kHz) for source light. The source light enters the water volume and scattered material is detected by a detector positioned where the acceptance angle forms a 117-degree intersection with the source beam. Figure 3 shows the optical configuration for the ECO-BB2F. The instrument has an operational temperature range of 0 - 30 degrees Celsius, and a depth rating of 600 m.

The Consilium SAL 860T is a dual axis Doppler speed log operating on the principle of acoustic echo correlation. The instrument is capable of independently measuring relative, true longitudinal and transversal speed and depth. The system is redundant and can also be used as a docking system. The T denotes a new bottom tracking main unit, built on digital signal processing technology, and features a patented hydroacoustic transducer. The transducer contains one pair of piezoelectric elements oriented parallel to the longitudinal axis of the vessel to measure the component (F) of the relative speed, and five piezoelectric elements, grouped in a patented way, to measure the components of the absolute speed. All elements work both for radiation and for reception. Sound energy is emitted vertically to the ground, perpendicular to the bottom of the ship. Relative velocity (WT) is measured at 4 MHz (pulse mode). To measure the absolute speed (BT), a frequency of 150 kHz is used, sound reflection comes from the ground. The same frequency is also used to measure depth. The multi-element hydroacoustic transducer allows measuring absolute velocity vectors in 12 directions - through 30 along the entire horizon, which provides high-precision calculation components (Vx) and (V) of the ship's speed. In addition, simultaneous measurements of the absolute and relative speed of the vessel make it possible to calculate the speed of the current. This feature is implemented in the ���SAL-860��� log (���Docking Log���). The instrument is capable of measuring within the range of -8 to +30 knots and in depths from 3 to 300 metres, with speed measurement error within +/- 0.1 knots or 0.5% (whichever is greater), distance covered within +/- 0.2% and depth under the keel within +/- 1%.

An instrument that collects and analyses aerosol particles continuously. It can be used for air quality monitoring; real-time source apportionment; emissions testing; climate change research; health effects research; and combustion research. Air is drawn through a spot on a filter tape at a measured flow rate. The tape is illuminated by light while sensitive detectors measure the intensities of light transmitted through the collecting spot and an un-exposed portion of the tape, acting as a reference. As optically absorbing material accumulates on the spot, the intensity of light transmitted through it gradually decreases. The decrease in light intensity from one measurement to the next is interpreted as an increase in collected material. This increased amount is divided by the known air-flow volume to calculate the concentration. In this model two sample spots are collected from the same input air stream with different accumulation rates and analysed simultaneously. The two results are combined mathematically to eliminate the "Filter Loading Effect" nonlinearity and accurately measure the aerosol concentration. Additionally, the analysis is made at 7 optical wavelengths spanning the spectrum from 370 nm to 950 nm. Increases in optical absorption at shorter wavelengths may be interpreted in terms of the presence of so-called "Brown" carbonaceous material, usually an indicator of emissions from biomass combustion. This instrument can be integrated with other instruments including: Total Carbon Analyzer TCA08 for OC/EC analysis; CO2 and meteorological sensors for additional data; and external pump for high altitude BC monitoring. The measurement wavelengths are: 370, 470, 520, 590, 660, 880 and 950 nm. The air flow set-points are: 2, 3, 4 and 5 LPM. The instrument can function up to 3000m altitude, and temperatures between 10 and 40 degrees Celsius.

A freezing rain sensor originally manufactured by Goodrich. It is used to detect the presence if icing conditions for the prevention of damage to power lines, to warn of icy road hazards, and prevention of ice build-up on wind turbine blades or aeroplane wings. The 0871LH1 uses resonant frequencies to determine the presence of icing conditions. Its main component is a nickel alloy rod that has a natural resonant frequency of 40 kHz. As ice collects on the rod, the added mass causes the resonant frequency to decrease. When the frequency decreases to 130 Hz (or 0.02 inch layer of ice), an internal heater automatically defrosts the sensor. It can operate in two modes; Sensing mode, where it operates with no ice or with probe ice thickness below the set point; De-icing mode, where it operates with probe ice thickness exceeding the set point. It has a built-in test (BIT) feature which is performed on initial power-up and continually. It features RS-422 output and operates at 9600 bps.
