Example shark-derived temperature-depth profiles across four regions, with the distribution of all transmitted profile locations (October 2021 - April 2022). Top panels compare tag-derived profiles within a 1° × 1° grid cell on a given day to the concurrent control (CFSR) profile (black), with shark tag data showing minimum (blue) and maximum (red) temperatures. Summary statistics for each grid cell are provided in-panel. The bottom map shows all profile locations and maximum depths (N = 8,242), with colored diamonds marking example profiles, orange lines indicating the Gulf Stream, and the black line marking 200 m depth.
