CTD log at the oxygen deficient zone of the Eastern Tropical North Pacific (ETNP) for RV/Atlantis cruise AT37-12, April-May 2017

Abstract:

A total of 10 CTD casts were performed on AT37-12 focusing on sampling the waters of the oxygen deficient zone of the Eastern Tropical North Pacific (ETNP). Cast 7 could not be completed due to problems with the wire. This dataset reports the station, date, location, water depth and sampling depth of individual Niskin bottles.

Instruments

CTD - profiler

Supplied Name: CTD Sea-Bird rosette as part of R/V Atlantis

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.
