Altimeter
Supplied Name : Benthos model PSA-916
Instrument Type
Generic Description :
An instrument that measures height above a fixed surface. The data can be used to map ocean-surface topography and generate gridded surface height fields.
CTD Sea-Bird SBE 911plus
Instrument Type
Acronym : CTD SBE 911plus
Generic Description :
The Sea-Bird SBE 911 plus is a type of CTD instrument package for continuous measurement of conductivity, temperature and pressure. The SBE 911 plus includes the SBE 9plus Underwater Unit and the SBE 11plus Deck Unit (for real-time readout using conductive wire) for deployment from a vessel. The combination of the SBE 9 plus and SBE 11 plus is called a SBE 911 plus. The SBE 9 plus uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 plus and SBE 4). The SBE 9 plus CTD can be configured with up to eight auxiliary sensors to measure other parameters including dissolved oxygen, pH, turbidity, fluorescence, light (PAR), light transmission, etc.). more information from Sea-Bird Electronics
Fluorometer
Supplied Name : Wet Labs WETStar flow through
Instrument Type
Generic Description :
A fluorometer or fluorimeter is a device used to measure parameters of fluorescence: its intensity and wavelength distribution of emission spectrum after excitation by a certain spectrum of light. The instrument is designed to measure the amount of stimulated electromagnetic radiation produced by pulses of electromagnetic radiation emitted into a water sample or in situ.
Niskin bottle
Supplied Description :
Instrument Type
Generic Description :
A Niskin bottle (a next generation water sampler based on the Nansen bottle) is a cylindrical, non-metallic water collection device with stoppers at both ends. The bottles can be attached individually on a hydrowire or deployed in 12, 24, or 36 bottle Rosette systems mounted on a frame and combined with a CTD. Niskin bottles are used to collect discrete water samples for a range of measurements including pigments, nutrients, plankton, etc.
Photosynthetically Available Radiation Sensor
Supplied Name : Biospherical Instruments models QSP200L/QSR-240
Instrument Type
Acronym : PAR sensor
Generic Description :
A PAR sensor measures photosynthetically available (or active) radiation. The sensor measures photon flux density (photons per second per square meter) within the visible wavelength range (typically 400 to 700 nanometers). PAR gives an indication of the total energy available to plants for photosynthesis. This instrument name is used when specific type, make and model are not known.
Sea-Bird SBE 43 Dissolved Oxygen Sensor
Supplied Name : SBE 43 Dissolved Oxygen Sensor
Instrument Type
Acronym : SBE-43 DO
Sea-Bird SBE-3 Temperature Sensor
Instrument Type
Acronym : SBE-3 Temperature
Generic Description :
The SBE-3 is a slow response, frequency output temperature sensor manufactured by Sea-Bird Electronics, Inc. (Bellevue, Washington, USA). It has an initial accuracy of +/- 0.001 degrees Celsius with a stability of +/- 0.002 degrees Celsius per year and measures seawater temperature in the range of -5.0 to +35 degrees Celsius. more information from Sea-Bird Electronics
Sea-Bird SBE-4 Conductivity Sensor
Instrument Type
Acronym : SBE-4 Conductivity
Generic Description :
The Sea-Bird SBE-4 conductivity sensor is a modular, self-contained instrument that measures conductivity from 0 to 7 Siemens/meter. The sensors (Version 2; S/N 2000 and higher) have electrically isolated power circuits and optically coupled outputs to eliminate any possibility of noise and corrosion caused by ground loops. The sensing element is a cylindrical, flow-through, borosilicate glass cell with three internal platinum electrodes. Because the outer electrodes are connected together, electric fields are confined inside the cell, making the measured resistance (and instrument calibration) independent of calibration bath size or proximity to protective cages or other objects.
Transmissometer
Supplied Name : Wet Labs C-Star 25-cm
Instrument Type
Generic Description :
A transmissometer measures the beam attenuation coefficient of the lightsource over the instrument's path-length. This instrument designation is used when specific manufacturer, make and model are not known.
Wet Labs ECO-AFL/FL Fluorometer
Instrument Type
Acronym : ECO AFL/FL
Generic Description :
The Environmental Characterization Optics (ECO) series of single channel fluorometers delivers both high resolution and wide ranges across the entire line of parameters using 14 bit digital processing. The ECO series excels in biological monitoring and dye trace studies. The potted optics block results in long term stability of the instrument and the optional anti-biofouling technology delivers truly long term field measurements.
