Abstract:

This dataset contains conductivity, temperature, and depth data collected during R/V Bellows cruise BE-1311 of the offshore shelf of the Florida Panhandle Bight at the head of DeSoto Canyon from December 12-14, 2012. CTD data are reported for 18 sample sites. Thirteen samples collected during the cruise were analyzed for pigment concentrations. Pigment concentrations for 14 pigments are reported, and areas normalized to internal standards used to calculate these concentrations are provided. Water samples were analyzed at the Wetlands Research Laboratory at the University of West Florida for nutrient concentrations included 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.
