Alisha Ellis is a Geologist at the St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida.
As a geologist, Alisha Ellis' work been focused on analyzing coastal environmental change using geological and ecological data. She has experience with foraminifera microfossils, lithologic core logs, various physical sediment parameters, radioanalytical spectroscopy and the development of geochronologies using uranium series isotopes. She uses these proxies to assess short-term and long-term changes in marsh and estuarine environments to assess system feedbacks and how these environments are impacted by natural events and anthropogenic activities.

Mode and provenance of sediment deposition on a transgressive marsh
In this study, we use foraminifera as environmental indicators to aid in computing the historical volumetric inputs of estuarine sediments to adjacent marsh. These data can help assess the importance of estuarine sediment inputs to marsh accretion. The Grand Bay system (GBS), located on the southern coast of Alabama and Mississippi, has been described as a “self-cannibalizing bay-marsh complex” du

Emerging dominance of Paratrochammina simplissima (Cushman and McCulloch) in the northern Gulf of Mexico following hydrologic and geomorphic changes
Grand Bay estuary in coastal Mississippi and Alabama (USA) has undergone significant geomorphic changes over the last few centuries as a result of anthropogenic (bridge, road, and hardened shoreline construction) and climatic (extreme storm events) processes, which reduce freshwater input, sediment supply, and degrade barrier islands. To investigate how geomorphic changes may have altered the Gran

The effect of tropical and extratropical cyclones on coastal wetlands and marshes is highly variable and depends on a number of climatic, geologic, and physical variables. The impacts of storms can be either positive or negative with respect to the wetland and marsh ecosystems. Small to moderate amounts of inorganic sediment added to the marsh surface during storms or other events help to abate pr
