     "text": "We use reduced-complexity models to infer past changes in coastal systems and reconstruct past geomorphology, which can help predict future change. This animation displays modeled beach profile elevation as it has evolved at Parramore Island, Virginia. These data are based on geomorphic field investigations and measure distance (in kilometers) of cross-shore accretion. QS is the flux of sand to the beach and QD is the flux of sand from the beach to the active dune. Yellow represents sand, blue represents water, while green represents marsh."

Sediment cores can extend records of erosion and deposition further into the past than geophysical or remote sensing methods."

     "text": "Remote sensing allows us to assess changes in barrier island extent, inlet dynamics, overwash processes, and land cover at varying spatial scales. Different spectra, or frequency ranges, in satellite imagery help us classify land cover features. This is especially useful for rapidly changing coastal features, like new inlets, where we can use multiple forms of remotely sensed imagery to study their evolution."

In shallow marine environments, we acquire high-resolution multibeam and single-beam bathymetry \u2013 data that show the shape and depth of the seafloor. By repeating surveys in the same location annually or semi-annually, we track erosional or depositional processes that might impact the response of the barrier to storms, sea-level rise, or human intervention. We pair bathymetry with sub-bottom geophysics (e.g., Chirp), to explore sediment layers beneath the seafloor. On land, we examine what\u2019s beneath beaches and barriers using ground-penetrating radar (GPR) to learn about their evolution through time."
