Estimated Agricultural Use of Azoxystrobin Fungicide - 1996 to 2014

Map showing the change in modern sediment thickness in meters between 1996-1997 and 2011 offshore of Fire Island. Green areas indicate accretion and red a

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.

Fractures in bedrock transmit groundwater, and geologic mapping is conducted to provide the geologic framework for groundwater resource studies. This photo shows iron-oxide staining (Leisegang banding) from past groundwater flow along fractures formed prior to the rock having been blasted open during road construction.

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.
