This $705,728 Project Grant award, funded by the National Science Foundation's Geosciences Program (CFDA 47.050), supports a collaborative research effort to study the contribution of coastal systems to the atmospheric carbonyl sulfide budget. The project, led by The Trustees of Columbia University in the City of New York, will conduct a multi-faceted analysis of marine carbonyl sulfide emissions by:

  1. Directly measuring marine fluxes of carbonyl sulfide using an air-sea interaction tower on the U.S. Atlantic seaboard and in the Bering Sea, as well as through shipboard measurements.
  2. Collecting data on dissolved carbonyl sulfide, its isotopologues, and precursor gases to quantify sources.
  3. Integrating the data through data assimilation and modeling to significantly increase understanding of the marine source of this trace gas, which can provide insights into the global carbon cycle.

The project, scheduled to run from July 1, 2025 to June 30, 2028, also includes training for early-career scientists and graduate students.
