This National Science Foundation (NSF) Division of Polar Programs Project Grant award of $302,388 to Oregon State University supports research to understand the role of specific iron-binding organic ligands in governing iron biogeochemistry in the Southern Ocean. The project aims to integrate measurements of exopolysaccharides (EPS), siderophores, and total ligand concentrations to provide unprecedented insights into how the composition of organic ligands impacts iron supply and cycling in the Amundsen Sea region. The research plan involves a combination of field sampling and laboratory experiments, with field samples collected during the 2023 U.S. GEOTRACES GP17-ANT expedition. This work falls under the NSF Polar Programs (CFDA 47.078) which supports fundamental research to expand knowledge and understanding of the polar regions. The project will run from March 1, 2024 to February 28, 2026.
