Full Citation Examples
These files contain rasterized interpolated biomass distributions for fish and invertebrate species caught in NOAA Fisheries fishery-independent bottom trawl 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 bottom trawl surveys. This data set covers 7 regions of the United States: Northeast, Southeast, Gulf of Mexico, West Coast, Eastern Bering Sea, Aleutian Islands, and Gulf of Alaska.

Abstract: |
These files contain rasterized interpolated biomass distributions for fish and invertebrate species caught in NOAA Fisheries fishery-independent bottom trawl 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 bottom trawl surveys. This data set covers 7 regions of the United States: Northeast, Southeast, Gulf of Mexico, West Coast, Eastern Bering Sea, Aleutian Islands, and Gulf of Alaska. |
Purpose: |
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 bottom trawl 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. |

Lineage
Lineage Statement: |
The interpolated biomass distribution maps were created by conducting several processing steps of the raw fishery-independent bottom trawl survey catch-per-unit effort data, using R and Python scripts to clean and standardize the datasets and then generate the interpolate 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. |

Process Steps
Process Step 1
Description: |
The data was downloaded from the above sources as raw bottom trawl survey data. Please refer to the original source for detailed metadata information on each trawl survey. |

Phone (Voice): | 301-427-8100 |
Process Step 2
Description: |
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. |

Phone (Voice): | 301-427-8100 |
Process Step 3
Description: |
The processed data was then fed into a Python script to generate the interpolated biomass distribution maps. Species richness layers were generated for each region by year by summing up the biomass layers for a core set of species (defined as those caught every year of a survey). |
