Instruments

Altimeter

Supplied Description:

Instrument Type

Generic Name: Altimeter

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/379/

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

Supplied Name: CTD 911plus

Supplied Description:

R/V Endeavor is equipped with an SBE 911+ CTD: High quality ducted/pumped system with digiquartz pressure sensor and dual temperature and conductivity sensors. 6800-meter capability and data rate of 24 scans per second.

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

Supplied Description:

Instrument Type

Generic Name: LI-COR Biospherical PAR Sensor

Acronym: LI-COR Biospherical PAR

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0074/

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.

Niskin bottle

Supplied Name: Bottle

Supplied Description:

Instrument Type

Generic Name: Niskin bottle

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0412/

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.

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

Wet Labs ECO-AFL/FL Fluorometer

Supplied Name: WET Labs ECO-AFL/FL

Supplied Description:

Instrument Type

Generic Name: Wet Labs ECO-AFL/FL Fluorometer

Acronym: ECO AFL/FL

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0172/

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.

WET Labs {Sea-Bird WETLabs} C-Star transmissometer

Supplied Name: WET Labs C-Star

Supplied Description:

Instrument Type

Generic Name: WET Labs {Sea-Bird WETLabs} C-Star transmissometer

Acronym: WL CSTAR Trans

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0160/

Generic Description:

The C-Star transmissometer has a novel monolithic housing with a highly intgrated opto-electronic design to provide a low cost, compact solution for underwater measurements of beam transmittance. The C-Star is capable of free space measurements or flow-through sampling when used with a pump and optical flow tubes. The sensor can be used in profiling, moored, or underway applications. Available with a 6000 m depth rating.
