Alisha Ellis
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.

Estuarine and MaRsh Geology Research Project
The goal of the Estuarine and MaRsh Geology (EMRG) Research Project is to study how and where short- and long-term marsh and estuarine coastal processes interact, how they influence coastal accretion or erosion, and how they pre-condition a marsh’s resiliency to storms, sea-level change, and human alterations along the northern Gulf of Mexico (Grand Bay and Point aux Chenes, Mississippi and St...
