a Map of the Northeastern subarctic Pacific (NESAP) showing BGC-Argo float trajectories (colored dots; float IDs in legend), approximate float positions during the marine heatwave (MHW) peaks in 2015 and 2019 (black dots), and Line P stations sampled for pigments and genetics (magenta triangles, stations P20-P26). b, c Mean monthly chlorophyll-a to carbon ratio (Chl:C, dimensionless) integrated over 0-100 m. d, e Mean monthly particulate organic carbon (POC, mg m-2) for 0-100 m. f, g Mean monthly POC (mg m-2) for 100-300 m (upper mesopelagic). In each panel, lines are colored by year (see panel legends); MHW years (2014, 2015, 2019, 2020) are red. “Small particles” denotes the bbp-derived fraction <100 µm.
