Description

Salinity, temperature and light data from repeat visits to the western Gulf of Maine.

Methods & Sampling

Dataset acquisition description

Samples are taken monthly along a cross-shelf transect in coastal
waters offshore of New Hampshire (see locations below).
The CTD data served here are part of a full suite of data that were
collected at each station.

Deployment-specific acquisition description

This is an accumulation of all the deployments that went out to visit these four sites during these three years.

Supplied Name: CTD profiler

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.
