Ongoing climate warming is causing a dramatic loss of sea ice in the Arctic Ocean, and it is
projected that the Arctic Ocean will become seasonally ice-free by 2040. Many studies of …

Phagotrophic protists are key players in aquatic food webs. Although sequencing-based
studies have revealed their enormous diversity, ecological information on in situ abundance …

The Adventfjorden time series station (IsA) in Isfjorden, West Spitsbergen, Norway, was
sampled frequently from December 2011 to December 2012. The community composition of …

Small bacterivorous eukaryotes play a cardinal role in aquatic food webs and their
taxonomic classification is currently a hot topic in aquatic microbial ecology. Despite …

Phytoplankton phenology is a key driver of biological and chemical processes in marine
ecosystems because it directly affects cycling of nutrients, the strength of the biological …

The northern coast of Svalbard contains high-arctic fjords, such as Rijpfjorden (80° N 22°
30′ E). This area has experienced higher sea and air temperatures and less sea ice in …

Seasonal plankton time-series data are presented from Kongsfjorden from two years with
contrasting environmental conditions. Kongsfjorden (west coast of Spitsbergen–79° N) …

Seasonal sea ice is an important feature in Svalbard fjords for both the physical environment
and the ecosystem. Systematic sea-ice monitoring in Kongsfjorden, Svalbard, as a part of a …

The European Arctic is rapidly changing where increasing water temperatures and rapid
loss of sea ice will likely influence the structure and functioning of the entire ecosystem. This …

The change in the community structure of phytoplankton and bacterioplankton, and in the
degree of coupling between them as well as the environmental conditions, have substantial …
