"Physiological mechanisms supporting high net primary productivity
in the Western Antarctic Peninsula."
Shelf waters surrounding Antarctica represent some of the most efficient sinks for anthropogenic CO2 in the global ocean. The sink of CO2 is largely driven by an extremely productive, spring phytoplankton bloom, which also provides the basis for the Antarctic marine food web. These intense spring blooms occur while water temperatures remain near freezing (~-1 °C), which creates a number of challenges for phytoplankton photosynthesis. Recent fieldwork by our group over a six-month austral summer at Palmer Station in the Western Antarctic Peninsula has uncovered a number of physiological strategies utilized by cold-water phytoplankton to enable such high net primary productivity despite cold temperatures. These strategies will be discussed in the context of the bloom and how these may change in the future due to rapidly rising temperatures in the Western Antarctic Peninsula.
