Description

Sea-Bird CTD Data Files

These CTD data files were collected on most cruises. The raw and processed data were placed on CD-ROMs, usually in zipped and/or tar'ed form, and provided to the participants and the Data Management Office. The "asc" versions of the files are served, using the information collected from the "hdr" files. These files have been shipboard processed using standard SeaBird software to one decibar averaged intervals.

If a cruise is not represented here, there were no ascii files available to serve (lmg0103, lmg0106), or they have been post-processed and re-served (nbp0103, nbp0104, nbp0202, and nbp0204).

Instruments

CTD - profiler

Supplied Name: Conductivity, Temperature, Depth

Supplied Description:

CTD measurements taken, CTD unit unidentified, Sea-Bird CTD

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.
