Water temperature, acoustic travel time, pressure, and currents taken by current and pressure recording inverted echo sounders as part of the Southern Ocean Fronts and Eddies Project (SOFE) in the Southern Ocean from 2021-11-13 to 2025-11-28 (NCEI Accession 0312787)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 05:18 AM | Dataset Last Updated: March 10, 2026 at 12:00 AM
The goal of the Southern Ocean Fronts and Eddies project (SOFE) is to measure and diagnose ocean eddy heat fluxes in the lee of the Southeast Indian Ridge (SEIR) in the Antarctic Circumpolar Current (ACC). This location stands out as one of the major ACC eddy flux hot spots and as a region where the three ACC fronts converge closely together as they encounter the ridge complex.To achieve this goal, a coherent array of 16 current and pressure recording inverted echo sounders (CPIES) was deployed in the southernmost ACC front in November 2021 and recovered in 2025. The CPIES data are the highest quality versions with the least amount of processing. The collection and processing of the data are described in the report provided. Data are in NetCDF.
