This dataset reports species caught using longline and trap sets during the R/V Apalachee cruise AP-1415 from October 02 to October 10, 2014. The objectives of this project were 1) to use large chevron traps and demersal longlines to describe and examine differences in the species assemblages and relative abundances of demersal fishes associated with the eastern and western walls of DeSoto Canyon and the adjacent continental slope (75-2000 m deep), 2) to collect liver and bile samples from dominant species to examine spatial and depth-mediated differences in exposure to polycyclic aromatic hydrocarbons (PAHs), 3) to collect muscle tissue from all species for stable isotope analyses including using radiocarbon ratios to examine attenuation of long-term exposure to hydrocarbons, and 4) to 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 these objectives.

This dataset contains fish data collected using fish traps and demersal longlines and includes biological data, for some species, such as length and weights. Additional data include the dates, set locations (latitudes, longitudes), depth, water temperature, gear deployed and bait used. These data were collected during the R/V Apalachee cruise AP-1503 on March 30 to April 23, 2015. The objectives of this project included to describe and examine differences in species assemblage and relative abundance of demersal fishes in the Gulf of Mexico.

This dataset reports species caught using longline and trap sets during R/V Apalachee cruise in the DeSoto Canyon from July 18 to August 4, 2013. Species data includes species name, sex, weight, length, and maturity state, if available. It also reports if samples were collected from individuals for other analysis, though the results of those analysis are not reported. Information about the longlines set includes bait used, gear, effort, and sea state. Additional files in the dataset report pressure and temperature data collected during longline trapping activities. The overall objectives of this research include using large chevron traps and demersal longlines to describe and examine differences in the species assemblages and relative abundances of demersal fishes associated with the eastern and western walls of DeSoto Canyon and the adjacent continental slope (75-2000 m deep), and collecting specimens and samples (including curation of new species) to aid in resolving phylogenetic uncertainties and understanding life history traits in collected taxa.

This dataset reports species caught using longline and trap sets during the R/V Apalachee cruise AP-1410 from June 30 to July 08, 2014.

This dataset reports species caught using longline and trap sets during the R/V Apalachee cruise AP-1407 from May 28-30, 2014. The main objective of this project was to use large chevron traps and demersal longlines to describe and examine differences in the species assemblages and relative abundances of demersal fishes associated with the eastern and western walls of DeSoto Canyon and the adjacent continental slope (75-2000 m deep). The other objectives were to collect liver and bile samples from dominant species to examine spatial and depth-mediated differences in exposure to polycyclic aromatic hydrocarbons (PAHs), to collect muscle tissue from all species for stable isotope analyses including using radiocarbon ratios to examine attenuation of long-term exposure to hydrocarbons, and to 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.

CTD Data from the cruise BE-1415 on May 2014. The cruise will be sampling to document any residual hydrocarbons from the BP MC252 well eruption and provide time series hydrographic, water chemistry, sediment, and plankton data as a baseline and to document the physical and biological seasonal dynamics for the offshore shelf of the Florida Panhandle Bight at the head of DeSoto Canyon.
