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

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

Abstract

Deep inside every drop of water lie tiny signatures from rare forms of hydrogen and oxygen, known as isotopes. These isotopes contain different numbers of neutrons and act like nature’s recorder, revealing where water vapor came from and how it traveled across the globe and formed precipitation. Sensitive to both temperature and humidity along their pathways, these isotopes are stored in natural archives such as ice…
