"I was working in Dr. Martin's hydrogeochemistry lab when he offered to mentor me for some research during my senior year. Big Cypress was a natural choice for me since I had worked with samples from the area in previous experiments while aiding PhD students with their research."

Research Description

Impact of Sediment Mineralogy on Bioavailability of Phosphorus
My project deals with the bioavailability of phosphorus at Big Cypress National Preserve (BICY). BICY is a P-limited ecosystem due to a high abundance of carbonate minerals, but there is one location (the Tamiami Formation) that contains high concentrations of quartz sand. This project involves performing a sequential leeching experiment on sediment samples from two cypress domes with contrasting carbonate mineral abundances, and identifying how the phosphorus is bound in the sediment. By doing so, we can identify how the bioavailability of phosphorus differs by the sediment types present in BICY.
