This Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) provides $649,136 to Kent State University to examine iron cycling on the northern Alaskan continental shelves. The research will determine the distribution of reactive iron within shelf sediments, the controls on iron remobilization, and links between iron cycling and other nutrients, toxic trace metals, and economically important metals. The project includes an oceanographic expedition to collect water column, sediment, and potential ferromanganese crust samples across four transects, paired porewater and sediment geochemical analyses, and paleoceanographic reconstructions of past iron cycling changes. The project will also provide educational and outreach activities for students at Kent State University and in Alaska. This award reflects the National Science Foundation's mission to advance fundamental knowledge about polar regions and their environmental systems.
