The goal of this task is to map, characterize, and quantify cumulative episodic event-driven loss in northern Gulf of Mexico coastal wetlands over the past century using available remotely sensed data. Achievement of this goal will provide spatially explicit estimates of wetland loss/gain caused by episodic large-scale drivers versus changes from persistent drivers such as sea-level rise and...
The focus of this task is to examine the role that marsh and shoreline erosion contribute to the sediment budgets of the adjacent open-water estuarine system. Sediments derived from marsh shoreline erosion generally have higher organic matter content than sediments derived from the erosion of barrier islands or delivered by rivers. Understanding the sediment budget in these estuarine...
Assessing and quantifying dominant physical depositional and erosive processes in estuarine shoreline environments
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.
Geologic variability (changes in stratigraphy, modern sediment distribution and composition, and morphology) has long been associated with barrier island evolution over centennial and millennial time scales. However, the relative importance of geologic variability over shorter time scales (days to years) remains poorly understood.
