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 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 …

Due to its importance as a limiting nutrient for phytoplankton growth in large regions of the
world's oceans, ocean water column observations of concentration of the trace-metal iron …

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 …

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 …

Abstract The Amundsen Sea Polynya is experiencing large increases in glacial meltwater
input and hosts an extremely productive and long-lasting summer phytoplankton bloom …

Results from recent field studies in Antarctic sea ice show no clear differences in dissolved
iron (dFe) concentrations between pack ice sampled in East Antarctica (2.6–20.5 nmol/L), in …

Rather than being solid throughout, sea ice contains liquid brine inclusions, solid salts,
microalgae, trace elements, gases, and other impurities which all exist in the interstices of a …

Over the past two decades, with recognition that the ocean's sea-ice cover is neither
insensitive to climate change nor a barrier to light and matter, research in sea-ice …

Abstract The Western Antarctic Peninsula (WAP) displays high but variable productivity and
is also undergoing rapid change. Long-term studies of phytoplankton communities and …
