The survey biomass indices for all species within the mskeyrun project from the Bigelow era

Description

Survey data comes from Northeast Fisheries Science Center's Bottom Trawl Survey. Indices are calculated using the Survdat R package. This data set covers the Bigelow era of the bottom trawl survey from 2009 to 2019. No calibration factors have been applied for the change from Albatross IV to Bigelow. Data from the Albatross era (1968 - 2008) are in a separate data set (surveyIndexA4All). This data covers all species caught on the survey. For the data set containing only the focal species see surveyIndexHB.
