#' Historical cold pool area calculations (cpa_pre2021)
#'
#' Historical temperature cold pool and temperature band areas that were calculated prior to 2021 by Bob Lauth and Lyle Britt. Historical cold pool calculations were conducted in ArcGIS and used inverse distance weighting with a maximum of four nearest neighbor points for interpolation (search radius nmax = 4) and weighting function power equal to 2 (i.e., idp = 2). Default ArcGIS settings were used to generate rasters cells for interpolation (cell dimensions equal to the smaller horizontal or vertical dimension divided by 250). Protocols for including stations for interpolation varied among years but it was intended for all standard survey grid stations from the EBS survey to be included. In some years, it is possible that near-shore stations or red king crab resample stations were included in the calculations. Rasters were converted to polygon shapefiles and areas were calculated from polygons. The CRS used in ArcGIS .mxd files was North American Datum 1983 / Albers Equal Area Alaska (EPSG:3338)
