Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

How we got this date

NSF lists this award's end date as 31 August 2028.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 29 December 2028.

Abstract

This project examines the generation of potential energy at ocean gyre-scales (>1000 km) and its subsequent release to kinetic energy by mesoscale eddies. The investigators hypothesize that eddies of size 200-500 km are significant net generators of potential energy via eddy-induced upwelling and downwelling, which penetrate deep into the ocean water column. This process is an overlooked sink for mesoscale kinetic…
