Abstract:

I. OBJECTIVES 1) Use fish traps and demersal longlines to describe and examine differences in the species assemblages and relative abundances of demersal fishes in the Gulf of Mexico. 2) Collect liver and bile samples from dominant species to examine spatial and depth-mediated differences in exposure to polycyclic aromatic hydrocarbons (PAHs). 3) Collect muscle tissue from all species for stable isotope analyses including using radiocarbon ratios to examine attenuation of long-term exposure to hydrocarbons. 4) Collect specimens and samples (including curation of new species) to aid in resolving phylogenetic uncertainties and understanding life history traits in collected taxa. This dataset contains the metadata and sample data associated with the above objectives. This dataset includes data funded under FIO Y1.x035.000:0002 and FIO Y1.x038.000:0003.

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.
