Julie Bernier
Julie Bernier is a Geologist at the St. Petersburg Coastal and Marine Science Center.
I have worked at the USGS - St. Petersburg Coastal and Marine Science Center since 2003. My research interests include applying sedimentologic, stratigraphic, remote sensing, and geophysical techniques to better understand coastal wetland and barrier-island change at historic to geologic time scales.

Storm-Related Barrier Island Morphological Evolution
Storms quickly and dramatically alter barrier island environments by changing adjacent seafloor morphology, eroding beaches, scarping or leveling dunes, and sometimes creating new inlets. Measuring the magnitude of barrier island sediment movement during and after storms allows us to track rates of beach recovery, dune growth, and inlet-related alterations to barrier island sediment supply.
Barrier Island Sensitivity to Changes in Sediment Supply
Observations and models show that maintaining barrier islands requires a balance between sea-level rise and sediment supply. However, most estimates of sediment supply are not based on modern conditions, which could result in less accurate predictions of sediment fluxes. We explore how natural and human alterations impact modern sediment fluxes, or changes, on barrier islands – research that has...
Coastal Sediment Availability and Flux (CSAF) Capabilities
As part of the Coastal Sediment Availability and Flux project, we use innovative technology and integrate a variety of techniques to characterize barrier island environments, reconstruct their past history, and predict their future vulnerability.
Historical Wetland Loss - Subsidence and Wetland Loss Related to Fluid Energy Production, Gulf Coast Basin
Analysis of historical satellite imagery and previously interpreted land-classification datasets identified more than 4,600 km2 of low-lying wetlands in coastal Louisiana that converted to open water between 1932 and 2004.
Subsidence and Wetland Loss Related to Fluid Energy Production, Gulf Coast Basin
Research (2000 - 2011) at the St. Petersburg Coastal and Marine Science Center focused on better understanding the physical processes and human activities that contributed to historical wetland loss in coastal Louisiana and the spatial and temporal trends of that loss.
Wetland Subsidence and Erosion - Subsidence and Wetland Loss Related to Fluid Energy Production, Gulf Coast Basin
The magnitudes of subsidence and erosion at the wetland-loss core sites were estimated by comparing marsh-surface elevations, water depths, and vertical displacements of stratigraphic contacts that were correlated between short sediment cores.
