Picoeukaryote Plankton Composition off West Spitsbergen at the Entrance to the Arctic Ocean
Abstract Investigation of marine eukaryotic picoplankton composition is limited by missing morphological features for appropriate identification. Consequently, molecular methods are required. In this study, we used 454‐pyrosequencing to study picoplankton communities at four stations in the West Spi...
