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 focuses on the chemical cycling of iodine in the ocean. Ocean iodine chemistry is important to biological cycles and to atmospheric levels of iodine which in turn are important to ozone levels and other air quality indicators. In addition, changes in ocean iodine chemistry recorded in ocean sediments are used to study past changes in ocean oxygen levels. The project will generate a large, high-quality…
