Abstract:

This dataset contains conductivity, temperature, and depth data from R/V Bellows cruise BE-1322 of the offshore shelf of the Florida Panhandle Bight at the head of DeSoto Canyon from June 2nd to 4th, 2013. Water samples collected were analyzed by the Wetlands Research Laboratory at the University of West Florida for nutrient concentrations. Water samples were filtered in the lab and cell counts for phytoplankton species are reported. Phytoplankton were photographed using scanning electron microscopy and images are provided in this dataset.

Purpose:

To evaluate the biological diversity and trophic interactions among organisms ranging from primary producers to apex predators and from the deep-sea benthos to the coast. These data contribute to a food web model used to determine risks to ecosystem structure and function and regional economies following from extreme anthropogenic events (e.g., discharged and background hydrocarbon) and adaptive management strategies.
