CTD Sea-Bird SBE 911plus Supplied Name : SeaBird 911 plus system
Supplied Description :
SeaBird 911 plus system with twelve 12-liter Niskin bottles
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 : Wetlabs ECO Fluorometer
Supplied Description :
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 Name : 12-liter Niskin bottles
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.
Sea-Bird SBE 27 pH/O.R.P. sensor Supplied Name : SBE 27 pH/Oxidation
Supplied Description :
Instrument Type
Acronym : SBE 27 pH/Oxidation sensor
Generic Description :
The SBE 27 pH and O.R.P. (Redox) sensor combines a pressure-balanced, glass-electrode, Ag/AgCl reference probe and platinum O.R.P. electrode to provide in-situ measurements at depths to 1200 m. The replaceable pH probe is permanently sealed and is supplied with a soaker bottle attachment that prevents the reference electrode from drying out during storage. The SBE 27 is intended for use as an add-on auxiliary sensor for profiling CTDs (SBE 9plus; SBE 19, 19plus, and 19plus V2 SeaCAT; and SBE 25 and 25plus Sealogger).
Sea-Bird SBE 43 Dissolved Oxygen Sensor Supplied Name : dual Oxygen (SBE 43) sensors
Supplied Description :
Instrument Type
Acronym : SBE-43 DO
Sea-Bird SBE-3 Temperature Sensor Supplied Name : dual Temperature (SBE 3) sensors
Supplied Description :
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 Supplied Name : dual Conductivity (SBE 4) sensors
Supplied Description :
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.
