Defne is co-author with USGS' Neil Ganju of a 2017 study on how to estimate coastal salt marshes' potential longevity, based on their sediment budgets and the ratio of open water to vegetation.

Storm induced erosion of marsh shorelines can provide significant quantities of sediment to the bay altering the deposition patterns.

Box-cores provide a relatively undistributed look into the recent past to help better understand the processes contributing to sediment deposition and erosion.

The effects of sea-level rise will vary by differences in the geomorphology and ecology of the landscape.  Images show marsh (top left) rocky coast (top right), barrier beach (bottom left), and coastal bluff (bottom right)
