Strong and regionally distinct links between ice‐retreat timing and phytoplankton production in the Arctic Ocean
Abstract Recent rapid sea‐ice changes in the Arctic Ocean have been widely considered to alter phytoplankton bloom timing and primary production, but the magnitude and regionality of this effect remain unclear. Here, we examined the spatial patterns in bloom timing, bloom magnitude, and primary prod...
