Instruments

CTD Sea-Bird SBE 911plus

Supplied Description:

Instrument Type

Generic Name: CTD Sea-Bird SBE 911plus

Acronym: CTD SBE 911plus

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0058/

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: Wetstar WS3S

Supplied Description:

Wetlabs Wetstar WS3S

Instrument Type

Generic Name: Fluorometer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/113/

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.

Fluorometer

Supplied Name: wetstar WSCD

Supplied Description:

Wetlabs Wetstar WSCD

Instrument Type

Generic Name: Fluorometer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/113/

Generic Description:

Photosynthetically Available Radiation Sensor

Supplied Name: Biospherical QSP-200L

Supplied Description:

Instrument Type

Generic Name: Photosynthetically Available Radiation Sensor

Acronym: PAR sensor

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/122/

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.

Salinity Sensor

Supplied Name: SBE 4C

Supplied Description:

Instrument Type

Generic Name: Salinity Sensor

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/350/

Generic Description:

Category of instrument that simultaneously measures electrical conductivity and temperature in the water column to provide temperature and salinity data.

Sea-Bird SBE 43 Dissolved Oxygen Sensor

Supplied Name: SBE 43 Dissolved Oxygen Sensor

Supplied Description:

SBE 43

Instrument Type

Generic Name: Sea-Bird SBE 43 Dissolved Oxygen Sensor

Acronym: SBE-43 DO

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0036/

Generic Description:

The Sea-Bird SBE 43 dissolved oxygen sensor is a redesign of the Clark polarographic membrane type of dissolved oxygen sensors. more information from Sea-Bird Electronics

Sea-Bird SBE-3 Temperature Sensor

Supplied Name: SBE 3+

Supplied Description:

Instrument Type

Generic Name: Sea-Bird SBE-3 Temperature Sensor

Acronym: SBE-3 Temperature

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/134/

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

Transmissometer

Supplied Name:

Supplied Description:

Instrument Type

Generic Name: Transmissometer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/124/

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.
