This National Science Foundation (NSF) Award under the Geosciences Program (CFDA 47.050) supports fundamental research to characterize the physiological and environmental cycling of abundant osmolytes, which are small carbon-containing molecules produced by marine microorganisms. The $519,767 award to the University of North Carolina at Wilmington aims to quantify how environmental conditions, such as nutrient availability and temperature, impact the abundances and cycling rates of these...
This Project Grant award of $419,614 from the National Science Foundation's Geosciences Program (CFDA 47.050) will fund a collaborative research project at the University of Maryland Baltimore County (UMBC) and University of California Irvine. The project aims to quantitatively assess the influence of salt on the aqueous partitioning of water-soluble organic gases in the atmosphere. The research will involve field and laboratory measurements, reanalysis of prior atmospheric chemistry data, and...
This Project Grant award of $249,221 from the National Science Foundation's (NSF) Office of International Science and Engineering (OISE) program (CFDA 47.079) aims to improve the ability of oceanographers to study the marine carbon cycle. The project, a collaboration between U.S. and U.K. institutions, will make key advances towards: (i) quantifying changes in the global carbon cycle from the surface to the deep ocean, (ii) supporting the development of new ocean pH sensors, and (iii) enabling...
This $300,785 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a research project to characterize the chemical composition and bioavailability of dissolved organic matter released by marine nitrifying microorganisms. The project aims to determine how this material contributes to carbon cycling in the deep ocean, which may help improve biogeochemical models and inform potential marine carbon dioxide removal activities. The research will...
This $453,714 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support collaborative research on the role of shallow benthic fluxes in the coastal carbon cycle along the east coast of the United States. The primary awardee, Trustees of Boston University, will lead a team that will synthesize existing data sources, including observations and modeling results, to evaluate how seafloor sediments influence carbon, oxygen, and nutrient cycling in...
This $645,614 Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) supports research to uncover the processes governing the marine dissolved organic sulfur (DOS) cycle in the Pacific Ocean. The key objectives are to: 1) quantify the DOS inventory across the Pacific, 2) identify abiotic and biotic processes responsible for DOS production and removal, and 3) investigate the reactivity of DOS and its components through monthly sampling at the Bermuda-Atlantic...
This $422,265 Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) will fund a collaborative research project led by Oregon State University (OSU) to characterize the physiological and environmental cycling of abundant osmolytes in the ocean. The project aims to: 1) identify how different microbial taxa respond to nitrogen stress by producing distinct osmolytes, 2) measure rates of osmolyte assimilation and their metabolic fate, and 3) quantify osmolyte...
This Project Grant award for $540,281 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project between U.S. and U.K. scientists to better understand the linkages between the oceanic cycles of iron and carbon. The research aims to characterize the "colloidal shunt" mechanism, whereby dissolved iron forms aggregates with organic carbon to create particulate matter that sinks out of the upper water column. The project will...

This Project Grant award of $405,502 from 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, which will be conducted by a team of researchers from institutions in the US, Germany, and Israel, includes several key components:

  1. Direct marine flux measurements of carbonyl sulfide (OCS) using an air-sea interaction tower on the US Atlantic seaboard and in the Bering Sea, as well as shipboard measurements.
  2. Dissolved measurements of OCS and its isotopologues and precursor gases to quantify fluxes and resolve sources via sulfur isotopes.
  3. Data assimilation and modeling to significantly increase the understanding of the marine source of OCS.

The award also includes training opportunities for early-career scientists and graduate students. This multi-faceted research effort aims to advance the scientific community's knowledge of the global carbon cycle by addressing the missing sources of the trace gas carbonyl sulfide. The project will run from July 1, 2025 to June 30, 2028.
