From: Pan-Arctic marine biodiversity and species co-occurrence patterns under recent climate
(a) Climate and productivity hotspots in Arctic marine areas defined as areas of overlap of two or more large changes in summer (b) sea surface temperature (0.21 °C ≤ SSST ≤ 0.76 °C), (c) sea ice concentration (− 2% ≥ SSIC ≥ − 76%), (d) chlorophyll-a concentration (0.26 mg·m−3 ≤ SCHL ≤ 0.73 mg·m−3), and (e) zooplankton biomass (0.21 g·m−2 ≤ SZOOC ≤ 0.75 g·m−2). Hatched areas in (a) correspond to areas of species accrual (defined as areas with species gains ≥ 1 species/decade) over the entire study period. The maps were created using GMT 6.3.0 (https://docs.generic-mapping-tools.org/6.3/gmt.html).
