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 30 June 2029.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 October 2029.

Abstract

This project investigates how a major ocean current system, the Atlantic Meridional Overturning Circulation (AMOC), influences near-term changes in surface atmospheric conditions over the globe. Today’s earth system models (ESMs) yield widely conflicting results for both present-day AMOC strength and how much AMOC will slow in the future. This project will assess how both the present-day strength of the AMOC and the…
