Instruments

CTD Sea-Bird

Supplied Name: CTD

Supplied Description:

CTD (Sikuliaq equipment, SeaBird rosette)

Instrument Type

Generic Name: CTD Sea-Bird

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/130/

Generic Description:

Conductivity, Temperature, Depth (CTD) sensor package from SeaBird Electronics, no specific unit identified. This instrument designation is used when specific make and model are not known. See also other SeaBird instruments listed under CTD. More information from Sea-Bird Electronics.

MOCNESS

Supplied Description:

MOCNESS (Wishner: Multiple Opening Closing Net and Environmental Sensing System (Wiebe et al. 1985), 1 m2 system, 8 or 9 nets, 222 µm mesh, updated software and Sea-Bird SBE911plusCTD system (SIO upgrades), day and night vertically- stratified and horizontally-sequenced tows, Wishner et al. 2018)

Instrument Type

Generic Name: MOCNESS

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/NETT0097/

Generic Description:

The Multiple Opening/Closing Net and Environmental Sensing System or MOCNESS is a family of net systems based on the Tucker Trawl principle. There are currently 8 different sizes of MOCNESS in existence which are designed for capture of different size ranges of zooplankton and micro-nekton Each system is designated according to the size of the net mouth opening and in two cases, the number of nets it carries. The original MOCNESS (Wiebe et al, 1976) was a redesigned and improved version of a system described by Frost and McCrone (1974).(from MOCNESS manual) This designation is used when the specific type of MOCNESS (number and size of nets) was not specified by the contributing investigator.

Sea-Bird SBE 49 FastCAT CTD Sensor

Supplied Name: Wire Flyer

Supplied Description:

Wire Flyer (Roman development: oscillating deep towed hydrographic profiler with Sea-Bird 49 FastCAT CTD and Aanderaa 4831F oxygen sensor, Roman et al 2018)

Instrument Type

Generic Name: Sea-Bird SBE 49 FastCAT CTD Sensor

Acronym: SBE-49

Generic Description:

The SBE 49 FastCAT is a CTD sensor for use in autonomous platforms. It contains a SBE 3P temperature sensor, a SBE 4C conductivity sensor and a strain-gauge pressure sensor as standard. It can operate in autonomus (16 Hz per sec) or polled mode (transmits each sample). The sensor is depth-rated to 350 m (plastic housing) or 7000 m (titanium housing). Accuracy: +/- 0.002 deg C (temperature), +/- 0.0003 S/m (conductivity), 0.1% of full scale range (pressure).

Tucker Trawl

Supplied Name: Tucker trawl net

Supplied Description:

MTT + MOC (Seibel: large Tucker trawl net (3 m2 mouth, 100 m long) with MOCNESS software and sensors (Childress and Seibel 1998), large insulated closing cod end (Childress et al. 1978), live animal collections)

Instrument Type

Generic Name: Tucker Trawl

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/NETT0161/

Generic Description:

The original Tucker Trawl, a net with a rectangular mouth opening first built in 1951 by G.H. Tucker, was not an opening/closing system, but shortly thereafter it was modified so that it could be opened and closed. The original had a 183 cm by 183 cm flexible rectangular mouth opening 914 cm long net with 1.8 cm stretched mesh for the first 457 cm and 1.3 cm mesh for last 457 cm. 152 cm of coarse plankton or muslin netting lined the end of the net. Tucker designed the net to collect animals associated with the deep scattering layers, principally euphausiids, siphonophores, and midwater fish. (from Wiebe and Benfield, 2003). Currently used Tucker Trawls usually have 1-m2 openings and can have a single net or multiple nets on the frame.
