NOAA AFSC Bottom trawl data formatted for NCEAS Portfolio Effects working group ground fish analysis in the Gulf of Alaska (1984-2015)

These data are derived from the NOAA Resource Assessment and Conservation Engineering Division (RACE) of the Alaska Fisheries Science Center (AFSC) bottom trawl surveys (df35b.258.10) in preparation for a spatial analysis of the effects of the Exxon Valdez oil spill on groundfish communities in the Gulf of Alaska. The majority of this analysis was conducted by Andrew Shelton from the NOAA Northwest Fisheries Science Center for the portfolio effects working group at the National Center for Ecological Analysis and Synthesis at the University of California, Santa Barbara whose goal is to asses how diversity may have buffered against the effects of EVOS as well as other perturbations. Further and additional analyses can be accessed in additional packages in this repository.
