Oceanographic data collected during the EX2101: 2021 EM 304 Sea Acceptance Testing and Mapping Shakedown (Mapping) expedition on NOAA Ship OKEANOS EXPLORER in the Gulf of America and the North Atlantic Ocean from 2021-04-16 to 2021-05-10 (NCEI Accession 0235238)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 27, 2026 at 08:58 PM | Dataset Last Updated: December 03, 2025 at 12:00 AM
This dataset contains oceanographic data collected from NOAA Ship OKEANOS EXPLORER in the Gulf of America and the North Atlantic Ocean from 2021-04-16 to 2021-05-10. Data acquisition from shipboard sensors includes navigational data, meteorological data (altimetry, conductivity, depth, echo sounder, fluorescence, oxygen, pressure, relative humidity, salinity, sound velocity, temperature, turbidity, water temperature, wind, wind speed), and vehicle data (ROV time to surface, traction winch data, line rate data). Additional data includes Profile Data (ASVP, CTD, and XBT) and ADCP Data.
