Description

CTD data from CGOA trawl cruises

Two related data objects:
Trawl catch data
Fork length data from trawls

From PI: All CTD Data were collected using a Seabird Seacat SBE 19 CTD, equipped with a WetStar fluorometer.

Additional information related to the events listed in these files can be queried from the GLOBEC event logs on file for each cruise.

BCO-DMO data manager processing notes:
* Version 2 (2021-06-08) replaces version 1 (2008-10-23). Character encoding converted to utf-8. A seabird headerline which was in the middle of the dataset as a data line was removed.

Instruments

CTD Sea-Bird SEACAT 19

Supplied Name: CTD Seabird 19

Supplied Description:

Also called Seacat, with pump and Wetlabs fluorometer. Lowered to 100m depth at all fish stations.

Instrument Type

Generic Name: CTD Sea-Bird SEACAT 19

Acronym: CTD SBE 19

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0042/

Generic Description:

The Sea-Bird SBE 19 SEACAT Recorder measures conductivity, temperature, and pressure (depth). The SEACAT is self-powered and self-contained and can be deployed in profiling or moored mode. The SBE 19 SEACAT was replaced in 2001 by the 19plus. more information from Sea-Bird Electronics

Fluorometer

Supplied Description:

Wetlabs

Instrument Type

Generic Name: Fluorometer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/113/

Generic Description:

A fluorometer or fluorimeter is a device used to measure parameters of fluorescence: its intensity and wavelength distribution of emission spectrum after excitation by a certain spectrum of light. The instrument is designed to measure the amount of stimulated electromagnetic radiation produced by pulses of electromagnetic radiation emitted into a water sample or in situ.
