NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 29 December 2028.

Understanding how Earth functions and how it has changed over time requires precise measurements of chemical signatures found in natural materials like lake sediments, fossils, and organic matter. This project supports the acquisition of a new isotope ratio mass spectrometer (IRMS) at the University of Minnesota Duluth’s Large Lakes Observatory (LLO), enhancing the capacity for high-precision analyses of stable…
