Instruments

CTD - profiler

Supplied Name: CTD

Supplied Description:

Instrument Type

Generic Name: CTD - profiler

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

Generic Description:

The Conductivity, Temperature, Depth (CTD) unit is an integrated instrument package designed to measure the conductivity, temperature, and pressure (depth) of the water column. The instrument is lowered via cable through the water column. It permits scientists to observe the physical properties in real-time via a conducting cable, which is typically connected to a CTD to a deck unit and computer on a ship. The CTD is often configured with additional optional sensors including fluorometers, transmissometers and/or radiometers. It is often combined with a Rosette of water sampling bottles (e.g. Niskin, GO-FLO) for collecting discrete water samples during the cast.

This term applies to profiling CTDs. For fixed CTDs, see https://www.bco-dmo.org/instrument/869934.

Pump

Supplied Name:

Supplied Description:

A "Little Giant" brand pump was used to retrieve water from depth for animal culture. This goal is to have large amounts of water of the appropriate salinity, DIC/TA and temperature to replicate the conditions the animals experience in situ. To achieve this, six "pteropod ptransporter" garbage cans were brought onboard and held in a plastic cage.

Instrument Type

Generic Name: Pump

Generic Description:

A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action. Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift, displacement, and gravity pumps

Reeve Net

Supplied Description:

150 micron mesh.

The objective of Reeve net sampling was to gently collect live specimens to be sampled for culturing experiments. These trawls were short in duration and aimed to maximize pteropod catch.

Instrument Type

Generic Name: Reeve Net

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/NETT0147/

Generic Description:

A Reeve Net is a conventional ring net with a very large acrylic cylindrical cod-end (30 liters) designed to collect fragile gelatinous animals. The net is lowered to a particular depth and then hauled slowly back to the surface (5-10 m/min). Reeve (1981) also described a double net system with no bridle and flotation at the net mouth that is attached to a roller mechanism that rides on a tow wire.
The roller system is locked in place by a pressure release device. Once below a set pressure, the roller
and nets are released and they float slowly up the wire, gently collecting the zooplankton, without being
influenced by the motion of the vessel and associated vertical wire movements. (from Wiebe and Benfield, 2003)
