This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $569,435 to Northeastern University to conduct research on the impacts of plastic-derived dissolved organic carbon (PDOC) on ocean biogeochemistry and the biological carbon pump. The core hypothesis is that bacteria consuming PDOC will compete with phytoplankton for key nutrients like nitrogen and phosphorus, reducing new production and the strength of the biological carbon pump. The...
The National Science Foundation awarded a $429,900 three-year Project Grant to the University of New Hampshire under the Geosciences program (CFDA 47.050) to support the collaborative research project "Plastic Spiraling in River Networks." The goal of the project is to determine the controls on watershed plastic fluxes using fieldwork and modeling. Specifically, the grant will fund research from October 1, 2021 to September 30, 2024 to better understand how plastic debris moves...
The National Science Foundation awarded a $243,076 Project Grant to Northeastern University under the Geosciences program (CFDA 47.050) for the period of September 1, 2021 through August 31, 2023. The grant will support the collaborative research project "Assessing the Contribution of Plastics to Marine Particulate Organic Carbon." The Geosciences program seeks to expand fundamental knowledge and understanding of the integrated Earth system through basic research in atmospheric,...
This National Science Foundation (NSF) Project Grant, awarded under the Geosciences program (CFDA 47.050), is providing $300,000 in funding to the University of Rochester from September 1, 2024 through August 31, 2026. The goal of this project is to determine how the presence of microplastics in the ocean may impact the distribution of naturally-occurring radioactive isotopes, which are commonly used to track processes associated with natural particles like sediments and biological materials....
This $519,767 Project Grant was awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) to the University of North Carolina at Wilmington (UNCW) from September 1, 2024 to August 31, 2027. The grant will fund research to characterize the production, cycling, and environmental responses of abundant organic compounds called osmolytes in marine microbial communities. The study aims to quantify the role of osmolytes in the ocean's carbon cycle and improve predictions of how...
This National Science Foundation (NSF) Geosciences program Project Grant (CFDA 47.050) awarded to the University of New Hampshire (UNH) provides $155,302 to support collaborative research on the contribution of allochthonous (externally-derived) dissolved organic nitrogen (DON) to biological nitrogen demand in the subtropical North Pacific Ocean.
The research expedition will depart from San Diego, CA and end in Honolulu, HI to study the production, accumulation, chemical composition, and...
The National Science Foundation Division of Ocean Sciences awarded a $371,107 project grant to the University System of New Hampshire to support the research project "COLLABORATIVE RESEARCH: WHAT CONTROLS THE MARINE REFRACTORY DOC RESERVOIR?" from July 15, 2021 through June 30, 2024.
The grant funds basic research into the integrated earth system through the Geosciences program (CFDA 47.050). Specifically, the collaborative research project seeks to expand understanding of the...
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...
The National Science Foundation (NSF) Division of Ocean Sciences awarded a $346,823 Project Grant to the Regents of the University of Colorado (doing business as the University of Colorado) to conduct research under the NSF Geosciences program (CFDA 47.050). This research project aims to better understand how transformations to microplastics in coastal environments impact their regional-scale transport and fate. The study will use Lagrangian tracers and existing hydrodynamic modeling to...
This $137,593 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research to improve understanding of the biological carbon pump in the ocean's oxygen minimum zones. The project aims to measure particle abundance, size, and sinking rates, as well as the processes that break down organic matter, across the oxic-anoxic transition in the Eastern Tropical North Pacific. The researchers will incorporate these new observations into a mechanistic...
