<p>NOAA Fisheries and its partners conduct fisheries-independent surveys in 8 regions in the US (Northeast, Southeast, Gulf of Mexico, West Coast, Gulf of Alaska, Bering Sea, Aleutian Islands, Hawai’i Islands). These surveys are designed to collect information on the seasonal distribution, relative abundance, and biodiversity of fish and invertebrate species found in U.S. waters. Over 900 species of fish and invertebrates have been identified in these surveys.</p>

These data were created as part of the DisMAP project to enable visualization and analysis of changes in fish and invertebrate distributions. This survey points layer provides information on both the locations where species are caught in several NOAA Fisheries surveys and the amount (i.e., biomass weight catch per unit effort, standardized to kg/ha) of each species that was caught at each location. Information on species distributions is of paramount importance for understanding and preparing for climate-change impacts, and plays a key role in climate-ready fisheries management.
The Sample Locations were produced by NMFS OST in partnership with OceanAdapt at Rutgers University

The survey points layers were created by conducting several processing steps of the raw fishery-independent survey catch-per-unit effort data, using R and Python scripts to clean and standardize the datasets. The data processing workflow, as well as information on the original sources of the data, are provided in detail in the below Sources and Process Steps.
Data for Gulf of Alaska Sample Locations 1993 to 2021 was downloaded from https://www.fisheries.noaa.gov/alaska/commercial-fishing/alaska-groundfish-bottom-trawl-survey-data
Alaska Fisheries Science Center Bottom Trawl Survey
2023-04-01T00:00:00
The data was obtained from the above sources as raw survey data. Please refer to the original source for detailed metadata information on each survey.

The raw survey data was then processed using an R script, which combined the individual files collected for each regional survey into one dataset with standardized names and units across all regions, and removing unnecessary columns. During this processing step, decisions where made to in some cases trim a regions data to either eliminate certain years or strata based on evaluation of survey coverage for those years or strata.
