Description

Hydrographic data were collected using a Seabird CTD Niskin Bottle Rosette, deployed at a wire speed between 40 and 60 meters per minute.

Nutrient samples were filtered (GFF glass fiber) before analysis and analyzed using the US-JGOFS protocols (http://usjgofs.whoi.edu/protocols_rpt_19.html) at the UW Marine Chemistry Laboratory.

The Seabird CTD Niskin Bottle Rosette included the following sensors: Seabird 911 Conductivity Temperature Density meter; Seabird SBE 43 Dissolved Oxygen Sensor; WETLabs ECO Chlorophyll Fluorometer; Biospherical/Licor PAR/Irradiance Sensor; WETLabs C- Star Transmissometer.

CTD data were processed using Seabird proprietary data conversion software and factory calibration coefficients; dissolved oxygen voltage was aligned using a time advance of 2.33 seconds; downcast data were averaged into 1 meter bins. CTD data has been reprocessed and aligned and outliers have been removed. All data are considered final.

This data is available at National Centers for Environmental Information (NCEI).

A container, typically made of glass or plastic and with a narrow neck, used for storing drinks or other liquids.

CTD - profiler

Supplied Name:

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.
