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

Abstract

Calcium carbonate (CaCO3) produced by certain marine organisms contains numerous elements as impurities. The abundance of those impurities often correlates with key seawater parameters such as temperature. This serves as the basis for marine CaCO3 fossils to be used as archives (“paleo-proxies”) for past changes in marine environments. Such archives help improve future forecasting. Yet the underlying reasons driving…
