Fish and Invertebrate Interpolated Biomass Distribution Surfaces 20221201

Metadata Updated: March 1, 2024

These files contain rasterized interpolated biomass distributions for fish and invertebrate species caught in NOAA Fisheries fishery-independent surveys. 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.

Lineage The interpolated biomass distribution maps 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 and then generate the interpolated biomass layers. 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.
