Description

Vertical profile data collected by CTD in a subtropical, pelagic environment on R/V Walton Smith cruise, WS15161.

Methods & Sampling

The conductivity-temperature-depth (CTD) instrument package is a high resolution vertical profiling sampling system. It is instrumented with a set of environmental sensors including: Seabird CTD, Seabird dissolved O2, and Wet Labs Fluorometer (ECO). All data are passed via copper wire-core cable to an onboard computer, time-stamped for cross-referencing, and saved on a computer hard drive.

Data Processing Description

Temperature, salinity, pressure, depth, oxygen, and fluorescence data were binned using Seabird’s SeaSave software into 1 db pressure bins by finding the average value for each parameter. Only downcast data was used. Soak time at the surface was excluded from bin averages.

Latitude and longitude values were noted at the time of the cast.

Instruments

CTD Sea-Bird

Supplied Name: Seabird CTD

Supplied Description:

Instrument Type

Generic Name: CTD Sea-Bird

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/130/

Generic Description:

Conductivity, Temperature, Depth (CTD) sensor package from SeaBird Electronics, no specific unit identified. This instrument designation is used when specific make and model are not known. See also other SeaBird instruments listed under CTD. More information from Sea-Bird Electronics.

Fluorometer

Supplied Name: Wet Labs Fluorometer (ECO)

Supplied Description:

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.

Oxygen Sensor

Supplied Name: Seabird dissolved O2

Supplied Description:

Instrument Type

Generic Name: Oxygen Sensor

Acronym: Dissolved Oxygen Sensor

Generic Description:

An electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analyzed
