Phytoplankton succession in the eastern Fram Strait (August 2017 - July 2018) – Microscopic analysis of autonomously collected water samples -
The succession of phytoplankton in the Fram Strait was investigated at the AWI LTER (Long Term Ecological Research) observatory HAUSGARTEN at a fixed station (HG-IV; ~ 79°N , 4° E) for the first time. For this purpose, a moored automated sampling system ( at ~25 m water depth) was collecting samples...
