The Arctic sea-ice-scape is rapidly transforming. Increasing light penetration will initiate
earlier seasonal primary production. This earlier growing season may be accompanied by …

Sea ice plays an important role in high latitude biogeochemical cycles, ecosystems, and
climate. A complete understanding of how sea ice biogeochemistry contributes to these …

Abstract Background Climate change threatens Earth's ice-based ecosystems which
currently offer archives and eco-evolutionary experiments in the extreme. Arctic cryopeg …

The oxygenated hypolimnion accounts for a volumetrically significant part of the global
freshwater systems. Previous studies have proposed the presence of hypolimnion-specific …

Organic soil fertilizers, such as livestock manure and biogas digestate, frequently contain
bacteria carrying resistance genes (RGs) to antimicrobial substances and mobile genetic …

Viruses are recognized as important actors in ocean ecology and biogeochemical cycles,
but many details are not yet understood. We participated in a winter expedition to the …

Hypersaline aqueous environments at subzero temperatures are known to be inhabited by
microorganisms, yet information on community structure in subzero brines is very limited …

Arctic sea ice can be classified into two types: seasonal ice (first-year ice, FYI) and multi-year
ice (MYI). Despite striking differences in the physical and chemical characteristics of FYI and …

Antarctic sea-ice bacterial community composition and dynamics in various developmental
stages were investigated during the austral winter in 2013. Thick snow cover likely insulated …

The novel concept of the review is a focus on the organisms living in the sea ice and what
mechanisms they have developed for their existence. The review describes the physical …
