Research - Assessing and quantifying dominant physical depositional and erosive processes in estuarine shoreline environments

Collection of peat cores.
Example of wetland sediment sampling using a peat auger.

The goal of this task is to quantify physical and biogeochemical controls on sediment accretion and erosion in estuarine marsh-wetlands around the northern Gulf of Mexico and the Atlantic coast. Achievement of this goal will provide ground-truth data to compare with estimates of areal changes assessed through remote sensing techniques as well as establish a model of wetland response to episodic events such as hurricanes or persistent drivers like sea-level. While current statewide coastal monitoring networks provide critical information, especially with respect to recent (last 5 years) marsh accretion in restoration areas, these investigations have not addressed long-term, historical accretion rates for much of the northern Gulf of Mexico.
