Sea ice in the Arctic is one of the most rapidly changing components of the global climate
system. Over the past few decades, summer areal extent has declined over 30%, and all …

The growth of phytoplankton at high latitudes was generally thought to begin in open waters
of the marginal ice zone once the highly reflective sea ice retreats in spring, solar elevation …

Historically, sea ice loss in the Arctic Ocean has promoted increased phytoplankton primary
production because of the greater open water area and a longer growing season. However …

Dramatic declines in sea-ice cover in the Arctic Ocean in recent decades have the potential
to fundamentally alter marine ecosystems. Here we investigate changes in sea ice between …

Marine ecosystems at high latitudes are characterized by extreme seasonal changes in light
conditions, as well as a limited period of high primary production during spring and early …

Recent receding of the ice pack allows more sunlight to penetrate into the Arctic Ocean,
enhancing productivity of a single annual phytoplankton bloom. Increasing river runoff may …

The main environmental factors driving spatial patterns, variability and change in primary
production (PP) in the Arctic Ocean are reviewed. While instantaneous PP rates are …

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 …

In the southern Beaufort Sea of the United States and Canada, prior investigations have
linked declines in summer sea ice to reduced physical condition, growth, and survival of …

Global warming drives changes in oceanographic conditions in the Arctic Ocean and the
adjacent continental slopes. This may result in favourable conditions for increased biological …
