Description:In coastal West Antarctic Peninsula (WAP) waters, large phytoplankton blooms in late austral spring fuel a highly productive marine ecosystem. However, WAP atmospheric and oceanic temperatures are rising, winter sea ice extent and duration are decreasing, and summer phytoplankton biomass in the northern WAP has decreased and shifted toward smaller cells. To better understand these relationships, an Imaging FlowCytobotwas used to characterize seasonal (spring to autumn) phytoplankton community composition and cell size dur- ing a low (2017 –2018) and high (2018 –2019) chlorophyll ayear in relation to physical drivers (e.g., sea ice and meteoric water) at Palmer Station, Antarctica. A shorter sea ice season with early rapid retreat resulted in lowphytoplankton biomass with a low proportion of diatoms (2017 –2018), while a longer sea ice season with late
