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.

Data Parameters and Units:
