This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $499,806 to Bigelow Laboratory for Ocean Sciences to conduct collaborative research on the role of the "colloidal shunt" in linking the ocean's iron and carbon cycles. The project aims to better characterize the interactions between dissolved organic carbon, iron-binding ligands, and particulate iron phases, and how these processes impact the export of organic carbon through the biological pump. The research will combine field observations, experimental studies, and ocean biogeochemical modeling to understand the sensitivity of these linkages to future environmental and climate changes. The award supports the training of undergraduate, graduate, and postdoctoral researchers, as well as outreach to K-12 and undergraduate students. No sub-awards are planned under this grant.
