Source: R/datasets_erddap.R

Indices for annual average Effective Shannon Index (ESI) values for various fleet groupings and West Coast Ports Data derived from Pacific Fisheries Information Network (PacFIN; https://pacfin.psmfc.org/) and Alaska Fisheries Information Network (AKFIN; https://www.akfin.org/). Aggregation and manipulaton of vessel level annual revenue data to create effective shannon index. For details, see: Kasperski, S. and D.S. Holland 2013.
