Abstract:

This dataset contains the conductivity, temperature, and depth data from four sites sampled during R/V Weatherbird II cruise in the DeSoto Canyon from October 3rd to 5th 2012. Nutrient concentrations collected through lab analysis of water samples are also reported 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.
