CTD Sea-Bird 9 Supplied Name : CTD SBE 9
Supplied Description :
Sampling instruments consisted of a Sea-Bird Electronics SBE9plus CTD with dual pumps (SBE5), dual temperature (SBE3plus), reference temperature (SBE35RT), dual conductivity (SBE4C), dissolved oxygen (SBE43), transmissometer (Wetlabs), fluorometer (Wetlabs CDOM), and PAR sensor (Biospherical).
Instrument Type
Acronym : CTD SBE 9
Generic Description :
The Sea-Bird SBE 9 is a type of CTD instrument package. The SBE 9 is the Underwater Unit and is most often combined with the SBE 11 Deck Unit (for real-time readout using conductive wire) when deployed from a research vessel. The combination of the SBE 9 and SBE 11 is called a SBE 911. The SBE 9 uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 and SBE 4). The SBE 9 CTD can be configured with auxiliary sensors to measure other parameters including dissolved oxygen, pH, turbidity, fluorometer, altimeter, etc.). Note that in most cases, it is more accurate to specify SBE 911 than SBE 9 since it is likely a SBE 11 deck unit was used. more information from Sea-Bird Electronics
CTD-fluorometer Supplied Name : Wetlabs CDOM
Supplied Description :
The SBE9plus CTD contained a WetLabs fluorometer.
Instrument Type
Generic Description :
A CTD-fluorometer is an instrument package designed to measure hydrographic information (pressure, temperature and conductivity) and chlorophyll fluorescence.
LI-COR Biospherical PAR Sensor Supplied Name : PAR Sensor
Supplied Description :
The SBE9plus CTD contained a Biospherical PAR sensor.
Instrument Type
Acronym : LI-COR Biospherical PAR
Generic Description :
The LI-COR Biospherical PAR Sensor is used to measure Photosynthetically Available Radiation (PAR) in the water column. This instrument designation is used when specific make and model are not known.
Sea-Bird SBE 43 Dissolved Oxygen Sensor Supplied Name : SBE43
Supplied Description :
The SBE9plus CTD contained an SBE43 dissolved oxygen sensor.
Instrument Type
Acronym : SBE-43 DO
Sea-Bird SBE-3 Temperature Sensor Supplied Name : SBE3plus
Supplied Description :
The SBE9plus CTD contained dual SBE3plus temperature sensors.
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 : SBE4C
Supplied Description :
The SBE9plus CTD contained dual SBE4C conductivity sensors.
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 : WetLabs Transmissometer
Supplied Description :
The SBE9plus CTD contained a WetLabs transmissometer.
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.
