Our lab looks at diatoms, other microfossils, and terrigenous grains in marine sediments in order to reconstruct past sea ice extent.
Our lab is primarily focused on developing a quantitative proxy for past sea ice extent and seasonal duration. We use fossil diatom assemblages as recorders of past sea ice to reconstruct the long-term (millions of years) record of sea ice in the Bering Sea. But, diatoms can tell us much more about past ocean conditions. In collaboration with others we use a multi-proxy approach to untangle the st
