The R code and data to support the manuscript "Pacific salmon in the Canadian Arctic highlight a range-expansion pathway for sub-Arctic fishes" published by Dunmall & Langan et al. 2024 in Global Change Biology. Briefly, this study investigated the mechanisms behind variable, rising catches of Pacific salmon by subsistence fishers in the Canadian Arctic. Detailed descritptions of the data and the performed analyses are provided in the associated manuscript.

These salmon counts were then compared to sea surface temperature (SST) and sea ice data derived from the NOAA OI SST V2 High Resolution Dataset ( https://psl.noaa.gov/data/gridded/data.noaa.oisst.v2.highres.html) . Specifically, environmental data, cropped to ocean areas using a provided shapefile, were analyzed in a polygon in the Chukchi Sea (vertices: [68.3°N, 170.0°W], [68.3°N, ...
