This function converts NEFSC Bottom Trawl depth stata in "BTS_strata" shapefiles to a downsampled raster format, which is necessary for masking target rasters containing ecosystem data. Primarily an interal function used by stock_env()

Usage

resample_strat(svspp, season, mask_type)

Arguments

svspp	Species code as specified in data/species_list.csv
season	Season in which trawl survey occurred.
mask_type	Specifies raster masking behavior. Can be one of "nes", "gom", "gbk", "sne", or "unit". If mask is "unit", then returned time series reflect stock boundaries drawn from depth strata.
