Ocean temperature, salinity, current velocity, and temperature variance dissipation collected from EM-APEX floats during the SQUID project from 2023-02-19 to 2024-09-18 (NCEI Accession 0305618)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: May 29, 2026 at 08:36 PM | Dataset Last Updated: July 09, 2025 at 12:00 AM
Collection of temperature, salinity, ocean currents, and temperature variance dissipation (chi) profiles gridded on 1-meter pressure levels from profiling EM-APEX floats deployed in all ocean basins during the Sampling Quantitative Internal Waves Distribution (SQUID) experiment funded by the National Science Foundation as part of the Global Internal Waves project of the National Oceanographic Partnership Program (NOPP). There are 5 NetCDF files included in this package and are described in the readme.txt provided.
