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 2029.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 29 December 2029.

Abstract

Hydrothermal venting at ocean spreading centers releases iron and other metals to the global oceans and contributes to the formation of critical metal deposits. Upon venting, some of the iron forms dense sulfide minerals that fall to nearby sediments. As vent fluids mix with oxygen-rich seawater, most of the remaining iron forms iron oxide minerals that settle out of a spreading hydrothermal plume, while a small…
