The Earth's cryosphere comprises those regions that are cold enough for water to turn into
ice. Recent findings show that the icy realms of polar oceans, glaciers and ice sheets are …

A rigorous synthesis of the sea-ice ecosystem and linked ecosystem services highlights that
the sea-ice ecosystem supports all 4 ecosystem service categories, that sea-ice ecosystems …

Sea ice contains a large amount of dissolved organic matter (DOM), which can be released
into the ocean once it melts. In this study, Arctic sea ice DOM was characterized for its optical …

Archaea are widespread in marine sediments, but their occurrence and relationship with
natural salinity gradients in estuarine sediments is not well understood. This study …

Assemblages of the smallest of organisms–Bacteria, Archaea, and their viruses–can be
found throughout the brine network of sea ice, in surface features of the ice, and across the …

Numerical models can be a powerful tool hel** to understand the role biogeochemical
processes play in local and global systems and how this role may be altered in a changing …

Larger volumes of sea ice have been thawing in the Central Arctic Ocean (CAO) during the
last decades than during the past 800,000 years. Brackish brine (fed by meltwater inside the …

Abstract The Arctic Ocean receives a large amount of terrestrial dissolved organic matter
(DOM) from rivers and more than half of this is removed during its passage through the Arctic …

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 …

Drift ice, open water and under-ice water bacterial communities covering several
developmental stages from open water to thick ice were studied in the northern Baltic Sea …
