S-MODE L2 Shipboard Acoustic Doppler Current Profiler Measurements Version 1

Published by NASA/JPL/PODAAC | National Aeronautics and Space Administration | Catalog Last Checked: May 18, 2026 at 03:06 PM | Dataset Last Updated: May 11, 2026
This dataset contains shipboard Acoustic Doppler Current Profiler (ADCP) measurements from the Sub-Mesoscale Ocean Dynamics Experiment (S-MODE) during a pilot campaign and two intensive operating periods (IOPs) conducted approximately 300 km offshore of San Francisco during Fall 2021, 2022, and Spring 2023. S-MODE aims to understand how ocean dynamics acting on short spatial scales influence the vertical exchange of physical and biological variables in the ocean. The ADCP was mounted to the bottom of the hulls of the research vessels deployed during each campaign, measuring horizontal and vertical currents, as well as acoustic backscatter from approximately 3 m to 50 m depth along the ship’s track. The data are available in netCDF format with dimensions of time and depth.
