Inundated marsh at Forsythe National Wildlife Refuge, New Jersey.

Surface sediments will be analyzed for various physical parameters that will be used as initial conditions in hydrodynamic and sediment transport models.

Relative seagrass biomass in West Falmouth Harbor, MA, under current and potential future nitrogen loading scenarios. Seagrass biomass increases in western (seaward) portions of the harbor while eastern (landward) areas see new colonization by seagrass.

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)

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.
