This National Science Foundation (NSF) Project Grant, awarded under the Geosciences program (CFDA 47.050), provides $658,901 to Woods Hole Oceanographic Institution (WHOI) from September 1, 2024 to August 31, 2027 to conduct research characterizing the production, cycling, and environmental impacts of abundant organic osmolytes in the ocean. The research will:

  1. Identify differential osmolyte production by microbial taxa in response to nitrogen stress using osmolyte measurements and transcriptomics.
  2. Measure rates of osmolyte assimilation and metabolic fate within marine microbial communities.
  3. Quantify osmolyte cycling across a coastal to oligotrophic transect, linking standing stocks, assimilation rates, and metabolic fate to microbial activity via metatranscriptomics.

This research aims to constrain the contribution of osmolytes to the labile dissolved organic carbon flux in the ocean and inform future efforts to quantify microbial production and consumption of individual labile molecules. The project will provide training opportunities for undergraduate students, a PhD student, and a postdoc, and will contribute to building oceanographic research capacity in Africa.
