Temperature, salinity, and depth data (Seabird MicroCat CTD) from Groves Creek salt marsh, Skidaway Island Georgia, USA, 2013-2015

Abstract:

This dataset includes temperature, depth, and salinity data from a Seabird MicroCat CTD deployed in Groves Creek salt marsh, Skidaway Island Georgia, USA, from July 2013 to March 2015.

Methods & Sampling

Microcat CTDs were attached to instrumented tripods in the creekbeds at stations S2 and S8. As with all of the other sonde deployments, instruments were swapped out on a 2-4 week schedule. Salinity data from the S2 site were often compromised by sediment- and bio-fouling of the conductivity tubes, particularly over the fall and winter of 2013-2014.

No post-processing has been done.

Data Processing Description

BCO-DMO Processing notes:
- added conventional header with dataset name, PI name, version date
- modified parameter names to conform with BCO-DMO naming conventions
- added station, lat, lon, date, time, ISO_DateTIme columns
- ISO Date format generated from date and time values
- reduced decimal places of CDOM and temperature to 3 places

Instruments

CTD - profiler

Supplied Name: SeaBird Microcat CTD

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.

CTD Sea-Bird MicroCAT 37

Supplied Name: Seabird MicroCat CTD

Supplied Description:

Instrument Type

Generic Name: CTD Sea-Bird MicroCAT 37

Acronym: CTD MicroCAT 37

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/350/

Generic Description:

The Sea-Bird MicroCAT CTD unit is a high-accuracy conductivity and temperature recorder based on the Sea-Bird SBE 37 MicroCAT series of products. It can be configured with optional pressure sensor, internal batteries, memory, built-in Inductive Modem, integral Pump, and/or SBE-43 Integrated Dissolved Oxygen sensor. Constructed of titanium and other non-corroding materials for long life with minimal maintenance, the MicroCAT is designed for long duration on moorings.

In a typical mooring, a modem module housed in the buoy communicates with underwater instruments and is interfaced to a computer or data logger via serial port. The computer or data logger is programmed to poll each instrument on the mooring for its data, and send the data to a telemetry transmitter (satellite link, cell phone, RF modem, etc.). The MicroCAT saves data in memory for upload after recovery, providing a data backup if real-time telemetry is interrupted.
