Nicholas M Enwright, Ph.D.
Nicholas Enwright is a Research Geographer at U.S. Geological Survey's Wetland and Aquatic Research Center in Lafayette, Louisiana.
He received his Ph.D. from Louisiana State University in 2019. Nicholas uses applied coastal geography research to understand how the spatial distribution and patterns of environments, such as barrier islands and coastal wetlands, are changing through time. His research program aims to further science related to natural resource assessments, restoration planning, and monitoring by: (1) developing new data using remote sensing techniques; (2) advancing methodologies for geospatial studies; (3) analyzing spatial data using geographic information science (GIS); and (4) forecasting potential future landscapes using geocomputational modeling. Currently, Nicholas' research team is working on projects that span the northern Gulf of Mexico coast and the Atlantic Seaboard.

Migration and transformation of coastal wetlands in response to rising seas
Coastal wetlands are not only among the world’s most valued ecosystems but also among the most threatened by high greenhouse gas emissions that lead to accelerated sea level rise. There is intense debate regarding the extent to which landward migration of wetlands might compensate for seaward wetland losses.

Barrier islands are dynamic environments that experience gradual change from waves, tides, and currents, and rapid change from extreme storms. These islands are expected to change drastically over the coming century due to accelerated sea-level rise and changes in frequency and intensity of storm events.
