Annual phytoplankton dynamics in coastal waters from Fildes Bay, Western Antarctic Peninsula
Abstract Year-round reports of phytoplankton dynamics in the West Antarctic Peninsula are rare and mainly limited to microscopy and/or pigment-based studies. We analyzed the phytoplankton community from coastal waters of Fildes Bay in the West Antarctic Peninsula between January 2014 and 2015 using...
