Description

CTD Data from Process cruises in 2001 and 2003

These CTD data are from five process cruises conducted in 2001 and 2003 in the CGOA.

NOTE 1: On the two cruises (HX271 and HX275) from 2003, "press" is provided (in dBAR). However, for cruises HX242, HX244, and HX247 (all in 2001), "depth" in meters is used rather than "press" in dBar. Since for all practical purposes, depth in meters and pressure in dBar are identical, for all five cruises, this parameter is called pressure in displaying the data.

Instruments

CTD - profiler

Supplied Name: Conductivity, Temperature, Depth

Supplied Description:

CTD measurements taken, CTD unit unidentified

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.
