This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award of $113,988 to the University of California, Santa Barbara (UCSB) aims to improve understanding of the biological carbon pump in ocean oxygen minimum zones. The researchers will conduct field observations in the Eastern Tropical North Pacific to measure characteristics of sinking particulate organic carbon, including particle abundance, size, sinking rates, and remineralization. These data will be...
This $632,314 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support a research project led by the University of California San Diego's Scripps Institution of Oceanography. The project aims to provide a better understanding of the physical and biogeochemical processes driving carbon cycling in the equatorial Pacific Ocean. Using a combination of ocean models, autonomous observations, and satellite data, the project will characterize...
This $908,131 project grant from the National Science Foundation Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), supports research to better understand how changing phytoplankton elemental use efficiencies may impact global ocean biogeochemistry as temperatures rise. A team of U.S. and U.K. researchers, led by the University of Southern California, will conduct laboratory experiments and field work to quantify the effects of temperature on nutrient elemental use...
This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award of $137,593 to the University of Maryland Center for Environmental Science (UMCES) will fund a collaborative research project to study the transfer of particulate organic carbon to the deep ocean in oxygen minimum zones. The project aims to improve understanding of the biological carbon pump by measuring particle abundance, size, sinking rates, and remineralization in the Eastern Tropical North Pacific...
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 $308,515 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project to study changes in pelagic ecosystem function and their impact on the carbon cycle from the Eocene to Oligocene periods (56-33.9 million years ago). The project aims to reconstruct changes in the South Atlantic subtropical gyre ecosystem and determine how these changes affected carbonate production and preservation during a time of...
This National Science Foundation (NSF) Project Grant under the Geosciences Program (CFDA 47.050) will support a collaborative research project to trace Pacific Ocean circulation and ventilation during the warm Pliocene epoch. The $387,909 award, made on August 15, 2024, will fund the generation of paleoceanographic records to test models suggesting a strong overturning circulation in the North Pacific during this period. The research will examine redox, temperature, and productivity proxies in...
The National Science Foundation (NSF) awarded a $314,306 Project Grant under the Geosciences program (CFDA 47.050) to the University of California San Diego's Scripps Institution of Oceanography. This 2-year grant, effective October 1, 2024, will support a postdoctoral fellowship to investigate the oceanographic and ecological factors affecting the abundance and distribution of mesopelagic organisms in the California Current ecosystem. The research aims to improve understanding of how...
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 National Science Foundation Project Grant under the Integrative Activities program (CFDA 47.083) provides $221,015 to the University of New Hampshire from February 2022 to January 2024 to investigate changes in Arctic Ocean phytoplankton and track the vertical export of organic carbon they produce. Working with optical oceanography experts at the Scripps Institution of Oceanography, the University will analyze data from 2010-2021 field campaigns measuring inherent and apparent optical...
