CTD data from R/V Atlantic Explorer cruise AE2207 to the Bermuda Atlantic Time Series (BATS) station in April 2022

Abstract:

This dataset includes CTD data from R/V Atlantic Explorer cruise AE2207 to the Bermuda Atlantic Time Series (BATS) station in April 2022. The CTD data was processed into .cnv files from cast hex files. Then, the data from the .cnv files were converted and saved as .csv files, with each file containing all scans for all variables contained in the .cnv files.

Methods & Sampling

CTD packages with Niskin rosettes were deployed to 300 meters with the exception of two deep casts: C01 to 2000 meters (where PAR sensor was removed) and C13 to 1000 meters. Casts are identified by two-digit ids preceded by a C, so that C01 is the first cast and C10 is the tenth cast etc.

Data Processing Description

Data Processing:
Data were converted from .hex files to .cnv files using SeaSave on default parameters. The .cnv files were then converted to .csv.

BCO-DMO Processing:
- concatenated separate .csv files into one dataset;
- created CAST column from individual file names;
- renamed fields to comply with BCO-DMO naming conventions.

Sea-Bird SBE-4 Conductivity Sensor

Supplied Name: Conductivity sensor (Seabird) SBE 4C

Supplied Description:

Instrument Type

Generic Name: Sea-Bird SBE-4 Conductivity Sensor

Acronym: SBE-4 Conductivity

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0417/

Generic Description:

The Sea-Bird SBE-4 conductivity sensor is a modular, self-contained instrument that measures conductivity from 0 to 7 Siemens/meter. The sensors (Version 2; S/N 2000 and higher) have electrically isolated power circuits and optically coupled outputs to eliminate any possibility of noise and corrosion caused by ground loops. The sensing element is a cylindrical, flow-through, borosilicate glass cell with three internal platinum electrodes. Because the outer electrodes are connected together, electric fields are confined inside the cell, making the measured resistance (and instrument calibration) independent of calibration bath size or proximity to protective cages or other objects.

Transmissometer

Supplied Name: Transmissometer (Wet Labs) C-Star

Supplied Description:

Instrument Type

Generic Name: Transmissometer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/124/

Generic Description:

A transmissometer measures the beam attenuation coefficient of the lightsource over the instrument's path-length. This instrument designation is used when specific manufacturer, make and model are not known.
