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 29 December 2029.

Abstract

The Antarctic Ice Sheet is a major source of uncertainty in future sea-level rise, yet its internal structure remains poorly understood. In many regions, radar sounding reveals a distinct layer in the deepest portion of the ice sheet, immediately above the bed. Unlike the overlying ice, this layer lacks visible internal reflections. This “basal ice unit” may form through intense deformation, elevated temperatures,…
