Fig. 11. Conceptual diagram illustrating past conditions vs. present conditions in the marginal ice zone west of the Antarctic Peninsula in the spring season (October to November). Spring conditions are inherently light-limited due to low solar zenith angles (SZA). Past conditions with lower wind speeds and shallower mixed layer depth (MLD) provided more favorable conditions for spring surface phytoplankton accumulation compared to present conditions.

New paper on changing phytoplankton phenology along the Antarctic Peninsula

In a recent paper, Jessica Turner, a PAL collaborator and Postdoctoral Associate at the University of Connecticut, found that phytoplankton blooms are starting later rather than earlier over time, likely driven by increased wind mixing. Her…
