Research Focus - Carbonate Deposition on the Ross Sea Shelf, Antarctica
My area of research focuses on carbonate deposition on Antarctic shelves. I have a great interest in examining past changes in climate, the oceans and depositional environments, especially concerning Antarctica and other polar regions. My advisor is Tracy Frank.
Quaternary carbonates on polar shelves provide analogs that will improve our ability to recognize and interpret ancient examples in the rock record, yet they remain understudied. This investigation integrates petrography, geochemistry, and radiocarbon dating to evaluate the origin, characteristics, and distribution of carbonate-dominated sediments recovered in 18 piston cores from the Ross Sea Shelf, Antarctica. Results indicate that carbonate deposition in the Ross Sea is highly localized in both space and time. Deposition was focused near the shelf break and along the western margins of banks on the NW Ross Sea Shelf. Results provide insights that will improve understanding controls on carbonate deposition in polar settings and will aid in interpretation of cold-water limestones found in the rock record.
