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

The Indian Pacific Warm Pool located in the tropics is the heat engine of the globe. Previous work has proposed that past episodic freshwater fluxes known as Heinrich Events in the Northern Hemisphere abruptly modulate tropical hydroclimate in regions like the Indian Pacific Warm Pool. In this project, cave deposits from the Philippines are used to reconstruct past hydrologic change and investigate the hydrologic…
