The survey biomass indices for the focal species within the mskeyrun project
Source:R/surveyIndex.r
surveyIndex.RdSurvey data comes from Northeast Fisheries Science Center's Bottom Trawl
Survey. Indices are calculated using the Survdat R package. This data
set covers the entire bottom trawl survey from 1963 to 2019.
All calibration factors have been applied for the change from Albatross IV to
Bigelow. Data from the Bigelow era (2009 - 2019) that are not converted are
in a separate data set (surveyIndexHB). This data only covers the focal
species of the MS Keyrun Project. For an expanded data set see
surveyIndexAll.
