The Arctic region is a harbinger of global change and is warming at a rate higher than the
global average. While Arctic warming is driven by increases in anthropogenic greenhouse …

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 …

Atmospheric new particle formation (NPF) and growth significantly influences climate by
supplying new seeds for cloud condensation and brightness. Currently, there is a lack of …

Throughout coastal Antarctica, ice shelves separate oceanic waters from sunlight by
hundreds of meters of ice. Historical studies have detected activity of nitrifying …

This study provides the first physically based mass‐balanced transport estimates of
dissolved inorganic nutrients (nitrate, phosphate, and silicate) for the Arctic Ocean. Using an …

The discovery that melting sea ice can fertilize iron (Fe)-depleted polar waters has recently
fostered trace metal research efforts in sea ice. The aim of this review is to summarize and …

The risk of aquatic invasions in the Arctic is expected to increase with climate warming,
greater shipping activity and resource exploitation in the region. Planktonic and benthic …

In large parts of the Southern Ocean, primary production is limited due to shortage of iron
(Fe). We measured vertical Fe profiles in the western Weddell Sea, Weddell‐Scotia …

Long-term patterns and drivers of ecosystem structure may be misunderstood if knowledge
of an ecosystem is derived primarily from a single season, a situation common in many …

Iron is a key nutrient for phytoplankton growth in the surface ocean. At high latitudes, the iron
cycle is closely related to the dynamics of sea ice. In recent decades, Arctic sea ice cover …
