NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 November 2030.

Abstract

Glacier melt has increased over the past decade. This accelerates sea-level rise and reduces Earth's ability to reflect incoming solar radiation. In warming polar regions, snow and glacial algae (SGA) grow on melting ice surfaces. This makes the ice darker and causes it to absorb more solar heat. That in turn melts more ice, which lets more algae grow, creating a positive feedback loop. This project studies where…
