CAREER: New insights into the ancient carbon cycle from siliceous deep-sea sediments — NSF Award to Utah State University (UT, $36
When silicate minerals in rocks are exposed to air and water, a “chemical weathering” reaction occurs that consumes carbon dioxide from the atmosphere. This process acts as a feedback on Earth’s climate – past, present, and future. Microscopic fossils preserved in deep-sea sediment record ancient warming events and the

| Abstract | When silicate minerals in rocks are exposed to air and water, a “chemical weathering” reaction occurs that consumes carbon dioxide from the atmosphere. This process acts as a feedback on Earth’s climate – past, present, and future. Microscopic fossils preserved in deep-sea sediment record ancient warming events and their recoveries. This project will analyze fossils from two distinct events in Earth history to understand how weathering rates respond to warm climates. The results will help predic |
