Item Identification

Title: Bottom Trawl Survey Catch-per-unit-effort
Status: In Work
Publication Date: 2022-03-07
Abstract:

NOAA Fisheries and its partners conduct bottom-trawl surveys in 7 regions in the US (Northeast, Southeast, Gulf of Mexico, West Coast, Gulf of Alaska, Bering Sea, Aleutian Islands). These surveys are designed to collect information on the seasonal distribution, relative abundance, and biodiversity of fish and invertebrate species found on the US continental shelves. Over 800 species of fish and invertebrates have been identified in these surveys.

Purpose:

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 the NOAA Fisheries bottom trawl surveys and the amount (i.e., biomass (weight catch per unit effort, kg/tow) 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.

Process Steps

Process Step 1

CC ID: 1167439
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.

Process Step 2

CC ID: 1167440
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.
