Environmental Data

Climate model data of marine layers (Sea Surface Temperature, Sea Surface Salinity, Sea Ice Cover, and Sea Ice Thickness) for the years 11,700 BP to 2020 CE that has been downscaled to 1.0ºx1.0º, masked to ocean areas 45ºN and above, and then calculated a 35-year running average on. Unprocessed climate model data is originally from Armstrong et al. (https://www.nature.com/articles/s41597-019-0277-1) and has been processed in the same manner as Westbury et al. (https://www.biorxiv.org/content/10.1101/2024.04.10.588858v1).
