Jennifer L Miselis, Ph.D.
I study the geology of coastal margins, specifically how sediment availability and fluxes influence coastal evolution over a variety of time and space scales. My work, which spans the Atlantic and Gulf coasts, supports coastal management by providing insight into modern and future coastal behavior, the extent and quality of sediment resources, and spatial variability in ecosystem resilience.
I received a B.S. in Marine Science and a B.A. in Spanish from the University of South Carolina and a Ph.D. in Marine Science with a specialization in Coastal Geology from the Virginia Institute of Marine Science. In 2008, I started an NRC Postdoctoral Research Associateship at the Naval Research Laboratory at Stennis Space Center in Mississippi. In 2010, I began working for the USGS at the Saint Petersburg Coastal and Marine Science Center, where I explore how geologic variability influences coastal system change over a range of time scales. Using geophysics, remote sensing, and sediment sampling, I characterize coastal geology and identify relationships between geology and coastal system response to climate and storms. Also, I integrate observations with models to quantify the impact of existing variability on future coastal response.

DUNEX Nearshore Geology
As part of the DUring Nearshore Event eXperiment (DUNEX) we are mapping the geology and morphology of the nearshore coastal environment before and after weather events to assess the impact storms have on coastal erosion.
USGS DUNEX Operations on the Outer Banks
DUring Nearshore Event eXperiment (DUNEX) is a multi-agency, academic, and non-governmental organization (NGO) collaborative community experiment designed to study nearshore coastal processes during storm events. The experiment began in 2019 and is scheduled for completion in the fall of 2021. USGS participation in DUNEX will contribute new measurements and models that will increase our...
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...
Shoreface Morphology and Geology
Exchanges of sediment between the shoreface and barrier islands allow barrier islands to adjust to changes in water level, such as those associated with storms or sea-level rise. Characterizing shoreface morphology and geology allows us to explore how past and present processes have impacted modern barrier island sediment transport and what that means for future barrier island evolution.
Modeling Barrier Island Evolution, Shoreface Morphology, and Overwash
Barrier island field observations provide information about past and current environmental conditions and changes over time; however, they can’t tell us about the future. Models can predict possible future behaviors but are only as good as their input data. By integrating both observations and models, we can extend observations and arrive at more realistic predictions of barrier island behavior...
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.
Coastal Sediment Availability and Flux (CSAF)
Sediments are the foundation of coastal systems, including barrier islands. Their behavior is driven by not only sediment availability, but also sediment exchanges between barrier island environments. We collect geophysical, remote sensing, and sediment data to estimate these parameters, which are integrated with models to improve prediction of coastal response to extreme storms and sea-level rise...
Coastal Change at Fire Island, a geonarrative
For more than two decades the U.S. Geological Survey has been researching Fire Island's offshore, nearshore, and barrier island systems to better understand drivers of coastal change and evolution. This geonarrative delves into how barrier islands change and evolve, demonstrates how seasons, storms and humans change beaches, and explores the role models play in predicting what the beach might look...
Coastal System Change at Fire Island, New York
Fire Island is a 50-km long barrier island along the south shore of Long Island, New York. The island is comprised of seventeen year-round communities; federal, state, and county parks; and supports distinct ecosystems alongside areas of economic and cultural value. In addition to providing resources to its residents, the barrier island also protects the heavily-populated mainland from storm waves...
