Seasonal Variability of Surface Ocean Carbon Uptake and Chlorophyll‐a Concentration in the West Antarctic Peninsula Over Two Decades Open
The Southern Ocean plays a vital role in global CO 2 uptake, but the magnitude and even the sign of the flux remain uncertain, and the influence of phytoplankton phenology is underexplored. This study focuses on the West Antarctic Peninsul…
