Chronic enrichment affects nitrogen removal in tidal freshwater river and estuarine creek sediments
We characterized nitrogen pollution patterns and quantified nitrogen removal capacity of habitats in two coastal systems. A tidal freshwater river experienced consistently high levels of nitrogen downstream of nutrient point source and sediments showed an upper limit for nitrogen removal. In contrast, nitrogen levels in an estuarine creek were variable, and downstream sediments did not exhibit the same limitation.

Storm characteristics influence nitrogen removal in an urban estuarine environment
We measured and mapped sediment nitrogen removal by flooded urban landscapes and compare to nitrogen loads during multiple tropical cyclones. We found (1) that habitat distribution within floodplains is important for landscape-scale nitrogen removal, (2) the amount of rainfall and wind during storms influence water quality and nitrogen removal capacity, and (3) urban habitats, such as lawns and stormwater ponds, can play an important role in maintaining water quality during storms.

Coastal squeeze reduces ecosystem services provided by wetlands and open spaces: insights from an interdisciplinary framework
We developed a novel framework to incorporate ecosystem services into land use planning at the local scale and demonstrate its application in a coastal city.

Habitat context affects nitrogen burial in restored Eastern Oyster reefs
This is the first study to directly measure nitrogen burial in Atlantic Coast oyster reefs. We evaluate the influence of tidal position and adjacent habitats on nitrogen burial by restored reefs.
