Areas in the drainage basins of the west Florida bays have been extensively mined for phosphate rock. Uranium parents and daughter products are enriched in phosphate material and disturbed during the mining process. Radium enrichment above background level in the middens and older sediments is anticipated and will be interpreted as increased land use change through mining. The Mg/Ca, Sr/Ca, and δ¹⁸O will be used to identify sites of groundwater influence as these sites might be enriched with groundwater radium. Nitrogen and phosphorus are anticipated to increase up core as a result of nutrient loading to coastal waters.

Gyroxanthin-diester and other carotenoid pigments are the biomarkers we will be using and will be analyzed on our HPLC.
