Measurements of near-surface ocean currents are essential for quantifying the Earth’s fundamental cycles (heat, energy, carbon, nutrients), and this observable has been designated as a priority for NASA earth observing in the 2020’s by the National Academies of Sciences 2017 Decadal Survey.
There have been steady advances in techniques for in situ and remote sensing of ocean surface currents that would enable global measurements, but validation against traditional measurements is in early stages. NASA’s Earth Ventures Suborbital-3 mission Sub-Mesoscale Ocean Dynamics Experiment (S-MODE) is bringing together multiple techniques for measuring surface currents, including in situ measurements from autonomous and drifting platforms and remote sensing measurements using radar and imagery-based techniques.
The TH42 Measuring ocean surface currents: S-MODE and prospects for satellite instruments will provide a first look at recently collected measurements from the multi-year S-MODE program, and it will discuss approaches to extend surface current measurements using satellite instruments. It also invites the ocean community to participate in the S-MODE campaign, data analysis, and science investigations.
Finally, it also seeks to build broad community support for a potential surface currents and winds mission that could be proposed to an expected NASA call in 2022/2023 for an Earth System Explorer mission.
The speakers will include Fabrice Ardhuin (IFREMER), Sarah Gille (UCSD), Luc Lenain (UCSD), Ernesto Rodriguez (JPL), and Nadya Vinogradova-Shiffer (NASA HQ).
