The distribution maps were produced for the Distribution Mapping and Analysis Portal (DisMAP) project. The distributions were generated from catch-per-unit-effort data from the fisheries-independent surveys. This data set covers 8 regions of the United States: Northeast, Southeast, Gulf of Mexico, West Coast, Eastern Bering Sea, Aleutian Islands, Gulf of Alaska, and Hawai’i islands. These data were created as part of the DisMAP project to enable visualization and analysis of changes in fish and invertebrate distributions. These interpolated biomass layers provide information on the spatial distribution of species caught in the NOAA Fisheries fisheries-independent surveys. 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 distribution maps were produced by NMFS OST in partnership with OceanAdapt at Rutgers University underDevelopment Karp, Melissa A (301) 427-8202 melissa.karp@noaa.gov pointOfContact Haverland, Timothy J 301-427-8137 301-713-4137 1315 East West Hwy Silver Spring MD 20910-3282 USA tim.haverland@noaa.gov custodian asNeeded aquatic sciences biosphere climate change distribution earth science ecological dynamics fish fisheries fishery-independent surveys invertebrates oceans range changes seasonal distribution species/population interactions theme Aleutian Islands East Coast Eastern Bering Sea Gulf of Alaska Gulf of Mexico Hawaii Islands Northeast US Southeast US West Coast place DOC/NOAA/NMFS/OST > Office of Science & Technology, National Marine Fisheries Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

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. The data was obtained from the above sources as raw survey data. Please refer to the original source for detailed metadata information on each trawl survey. 2022-12-01T00:00:00 NMFS Office of Science and Technology 301-427-8100 processor 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. 2022-12-01T00:00:00 NMFS Office of Science and Technology 301-427-8100 processor The processed data was then fed into a Python script to generate the interpolated biomass distribution maps. The layers were summed in each region by year to provide species richness layers for each region. 2022-12-01T00:00:00 NMFS Office of Science and Technology 301-427-8100 processor These maps were then uploaded to the NOAA Fisheries Mapping portal as ESRI Imagery mosaic layers for display on DisMAP. 2022-12-01T00:00:00 NMFS Office of Science and Technology 301-427-8100 processor Source Contribution: Data downloaded from https://www.fisheries.noaa.gov/alaska/commercial-fishing/alaska-groundfish-bottom-trawl-survey-data Alaska Fisheries Science Center Bottom Trawl Survey Source Contribution: Data downloaded from https://seamap.gsmfc.org/ Gulf of Mexico - SEAMAP Source Contribution: Data downloaded from: https://www.fisheries.noaa.gov/inport/item/18418 NWFSC Annual Bottom Trawl Survey Source Contribution: For Fall data: https://inport.nmfs.noaa.gov/inport/item/22560, For Spring data: https://inport.nmfs.noaa.gov/inport/item/22561 POC: Paul Kostovick (or Sean Lucey) Northeast Fisheries Science Center Bottom Trawl Survey Source Contribution: PIFSC BFISH survey, See InPort record for the survey data at https://www.fisheries.noaa.gov/inport/item/20969 PIFSC BFISH survey 2022-12-01 publication Source Contribution: Data downloaded from https://www2.dnr.sc.gov/seamap/Account/LogOn?ReturnUrl=%2fseamap%2fReports Sourtheast US - SEAMAP
