Long-term studies on West Antarctic Peninsula phytoplankton blooms suggest range shifts between temperate and polar species
The Western Antarctic Peninsula (WAP) experiences one of the highest rates of sea surface warming globally, leading to potential changes in biological communities. Long-term phytoplankton monitoring in Potter Cove (PC, King George Island, South Shetlands) from the 1990s to 2009 revealed consistently...
