Two decibar averaged CTD profiles collected at the Hydrostation S site in the Sargasso Sea from October 1988 through June 2025

Data presented here are CTD profiles from the Hydrostation S (or Panulirus) time series site located 20 km SE of Bermuda (32°10’N, 64°30’W) in the Sargasso Sea for October 1988 through June 2025. Profiles include basic CTD measurements of Pressure, Depth, Temperature, and Salinity, reported along with dissolved oxygen, beam attenuation, and relative fluorescence, at two-decibar averages. The profiles were collected during biweekly cruises to the site from October 1988 (cruise #60643) to June 2025 (cruise #61501). Data and samples have been collected using a SeaBird 9/11+ CTD and integrated Niskin rosette system.
