This $916,578 federal Project Grant awarded by the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) supports fundamental research to expand understanding of iron adaptation in marine phytoplankton across global oceans. The key objectives are to: Characterize iron storage capacities and limitation thresholds for 20 Synechococcus phytoplankton strains from 11 ecotypes across a range of ocean iron niches. Analyze gene regulation responses to varying iron availability for the 20...
This National Science Foundation (NSF) Geosciences program Project Grant, awarded to Georgia Tech Research Corporation, will investigate the biogeochemical and physical processes regulating the benthic flux and speciation of iron from non-upwelling continental margins. The $880,688 award, effective October 1, 2023 through September 30, 2026, aims to quantify the flux of iron from sediments to the water column in the western North Atlantic Ocean and western Mediterranean Sea. The research team...
The National Science Foundation Division of Ocean Sciences awarded a $260,366 Project Grant to the University of Washington's Office of Sponsored Programs to support collaborative research under the Geosciences program (CFDA 47.050). The research aims to conduct shipboard measurements of dissolved aluminum, iron, and manganese to trace inputs to the South Pacific Gyre and Southern Ocean from September 2021 through August 2024. The Geosciences program seeks to expand fundamental knowledge of...
This $334,856 National Science Foundation (NSF) Project Grant award to Kent State University supports research to study iron cycling in sediments in the Gulf of Alaska. The research aims to better understand the source of iron from sediments to the ocean water column in this high nutrient, low chlorophyll region, where iron limits primary productivity. The project will use a paired porewater and sediment geochemical approach to investigate the quantity, speciation, and remobilization processes...
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 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 $691,259 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support a collaborative research project to better understand the relationship between the oceanic cycles of iron and carbon. The award, titled "COLLABORATIVE RESEARCH: NSFGEO-NERC: THE COLLOIDAL SHUNT AS A CRITICAL NEXUS OF THE OCEAN IRON AND CARBON CYCLES," will be performed by researchers at Oregon State University. The project aims to characterize the "colloidal...
The National Science Foundation (NSF) awarded a $899,999 Project Grant through its Geosciences (CFDA 47.050) program to the J. Craig Venter Institute (JCVI) on May 1, 2024. The grant will support collaborative research to characterize a novel blue copper ferritin protein in marine phytoplankton and explore how this protein may provide an ecological advantage in iron-limited ocean environments. The research aims to advance the understanding of how iron limitation impacts marine ecosystems and...

The National Science Foundation (NSF), under its Geosciences program (CFDA 47.050), awarded a $374,800 Project Grant to the University of California, Los Angeles (UCLA) to investigate iron cycling and transport in the Eastern Tropical South Pacific (ETSP) region. The 3-year project, starting March 1, 2024, aims to:

  1. Understand the formation, maintenance, and transport of the iron plume in the ETSP anoxic waters, and

  2. Assess the impact of this anoxic iron cycling on the biogeochemistry of the broader tropical and subtropical Pacific Ocean.

To achieve these goals, UCLA researchers will develop and analyze a series of eddy-resolving iron cycle models, comparing the simulations against observational data collected during prior oceanographic expeditions. The project seeks to improve the community's ability to detect and interpret biogeochemical variations in this major ocean region. No sub-awards are planned under this grant.
