Ikaite is a metastable calcium carbonate hexahydrate (CaCO3· 6H2O), which naturally
occurs in environments characterized by temperatures of− 2 to+ 7° C. It is therefore …

Snow in the environment acts as a host to rich chemistry and provides a matrix for physical
exchange of contaminants within the ecosystem. The goal of this review is to summarise the …

Calcium carbonate (CaCO3) is abundant on Earth, is a major component of marine
biominerals and thus of sedimentary and metamorphic rocks and it plays a major role in the …

Although Antarctic sea ice is undergoing a slight increase in overall extent, major regional
changes are occurring in its spatio-temporal characteristics (most notably in sea ice …

At present, although seasonal sea-ice cover mitigates atmosphere-ocean gas exchange, the
Arctic Ocean takes up carbon dioxide (CO 2) on the order of− 66 to− 199 Tg C year− 1 (10 …

Observations from the last decade suggest an important role of sea ice in the global
biogeochemical cycles, promoted by (i) active biological and chemical processes within the …

The substantial reduction in summer Arctic sea ice extent observed in 2007 and 2008 and its
potential ecological and geopolitical impacts generated a lot of attention by the media and …

The role of ice in the formation of chemically active halogens in the environment requires a
full understanding because of its role in atmospheric chemistry, including controlling the …

Marine sedimentary ikaite is the parent mineral to glendonite, stellate pseudomorphs found
throughout the geological record which are most usually composed of calcite. Ikaite is …

Although salt rejection from sea ice is a key process in deep-water formation in ice-covered
seas, the concurrent rejection of CO2 and the subsequent effect on air–sea CO2 exchange …
