摘要

Arctic spring phytoplankton blooms, vital to polar marine ecosystems, have intensified and advanced in timing amid rapid sea ice decline. However, the physical drivers linking winter phytoplankton persistence to these changes remain unclear. Here we analyze a 17-year pan-Arctic satellite record from spaceborne LiDAR (Light Detection and Ranging), capable of detecting phytoplankton-related optical signals during polar night, here defined as the light-limited winter period (December–February), revealing that earlier sea ice retreat and the overwintering phytoplankton persistence jointly associate with bloom timing and magnitude. Our findings show that winter water column stability is statistically associated with overwintering chlorophyll levels, which are in turn linked to subsequent bloom intensity. These insights highlight the complex interplay between changing sea ice regimes and ocean stratification in shaping Arctic phytoplankton dynamics, with implications for ecosystem productivity and trophic interactions under ongoing climate change.
