In marinebon/ecoidx: Marine ecological indicators R package for CA Current IEA

Description Usage Format Source

Biodiversity indices (total abundance, species richness, Shannon-Weaver diversity, Pielou's evenness) of all taxa (also young-of-the-year rockfish and groundfish taxa, and forage taxa) caught in the RREAS (Rockfish Recruitment and Ecosystem Assessment Survey) mid-water trawl. This is a regional average of all net haul stations located from Point Reyes to Monterey CA.
