Quantifying Under‐Ice Phytoplankton Blooms in the Changing Arctic and Southern Oceans

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Historically, polar marine phytoplankton were thought to primarily grow after the seasonal breakup of sea ice, when there is plentiful light available in the surface ocean. However, observations of substantial productivity under sea ice has called this assumption into question.
