Vertical profiles of water quality parameters at sampling stations in the South Atlantic Bight from 2015-2020 (SAB BMA project)

Abstract:

Vertical profiles of depth, conductivity, salinity, temperature, pH, and dissolved O2 were measured on selected dates from 7 June 2018 to 10 August 2021 in nearshore shelf waters off Charleston, SC. The survey area was located in the region of 32° 42’ N, 79° 50’ W and 32° 51’ N, 79° 09’W. Profiles were obtained using a YSI 6820 sonde deployed by hand. These data were used to map the physical structure of the water column and assess inputs of groundwater effects on phytoplankton and benthic microalgae. Results may be of interest to others conducting research projects off Charleston, SC. Data were collected and interpreted by Jay Pinckney at the University of South Carolina, Columbia, SC.

Methods & Sampling

Methods & Sampling

Hand deployment of YSI 6810 sonde with measurements of water quality parameters at 1 m depth intervals to a maximum depth of 15 m.

Samples were taken from R/V Trinity, owned by a private charter company called Charleston SCUBA. This company is no longer in operation.

Data Processing Description

BCO-DMO Processing Notes:

Reformatted the data table so that the there is one header row, and this row is the first row in the table
Replaced column name spaces with underscores "_"
Replaced special character "δ" with "Sigma"
Rounded lat and long fields to 6 decimal places
Rounded all depth values to 3 decimal places
Standardized date time format to %Y-%m-%d %H:%M

Instruments

YSI Sonde 6-Series

Supplied Name: YSI 6810 Multi-parameter Sonde

Supplied Description:

Hand deployment of YSI 6810 sonde with measurements of water quality parameters at 1 m depth intervals to a maximum depth of 15 m.

Instrument Type

Generic Name: YSI Sonde 6-Series

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0737/

Generic Description:

YSI 6-Series water quality sondes and sensors are instruments for environmental monitoring and long-term deployments. YSI datasondes accept multiple water quality sensors (i.e., they are multiparameter sondes). Sondes can measure temperature, conductivity, dissolved oxygen, depth, turbidity, and other water quality parameters. The 6-Series includes several models. More from YSI.
