Junbong Jang of the USGS Woods Hole Coastal and Marine Science Center measures index properties on sediment collected during the Indian Government’s National Gas Hydrates Program (NGHP-02) drilling expedition offshore from eastern India in the summer of 2015.

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.

USGS technician Barry Irwin uses a GPS rover system to locate one of the targets used to calibrate the field of view for the beach cam. Three other larger targets are visible in the background.
