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 March 2031.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 29 July 2031.

Abstract

When silicate minerals in rocks are exposed to air and water, a “chemical weathering” reaction occurs that consumes carbon dioxide from the atmosphere. This process acts as a feedback on Earth’s climate – past, present, and future. Microscopic fossils preserved in deep-sea sediment record ancient warming events and their recoveries. This project will analyze fossils from two distinct events in Earth history to…
