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 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. 2026-06-01T00:00:00 NMFS Office of Science and Technology 301-427-8100 processor The data was obtained from the above sources as raw survey data.
