Anthropogenic mercury (Hg) emissions have driven marked increases in Arctic Hg levels,
which are now being impacted by regional warming, with uncertain ecological …

The micronutrient iron is now recognized to be important in regulating the magnitude and
dynamics of ocean primary productivity, making it an integral component of the ocean's …

Nutrient availability limits phytoplankton growth throughout much of the global ocean. Here
we synthesize available experimental data to identify three dominant nutrient limitation …

Abstract The Arctic Ocean is a fundamental node in the global hydrological cycle and the
ocean's thermohaline circulation. We here assess the system's key functions and …

Freshwater discharge from glaciers is increasing across the Arctic in response to
anthropogenic climate change, which raises questions about the potential downstream …

A major surface circulation feature of the Arctic Ocean is the Transpolar Drift (TPD), a current
that transports river‐influenced shelf water from the Laptev and East Siberian Seas toward …

Abstract The Marginal Ice Zone (MIZ) of the Arctic Ocean is changing rapidly due to a
warming Arctic climate with commensurate reductions in sea ice extent and thickness. This …

Rising temperatures in the Arctic Ocean region are responsible for changes such as
reduced ice cover, permafrost thawing, and increased river discharge, which, together, alter …

Rising atmospheric CO 2 concentrations will have profound effects on atmospheric and
hydrographic processes, which will ultimately modify the supple and chemistry of trace …

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 …
