The Atlantic gateway to the Arctic Ocean is influenced by vigorous inflows of Atlantic Water.
The high-latitude impacts of these inflows have strengthened owing to climate change …

The Arctic sea-ice-scape is rapidly transforming. Increasing light penetration will initiate
earlier seasonal primary production. This earlier growing season may be accompanied by …

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 …

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 …

After a decade with nine of the lowest arctic sea-ice minima on record, including the
historically low minimum in 2012, we synthesize recent developments in the study of …

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 …

As Arctic sea ice deteriorates, more light enters the ocean, causing largely unknown effects
on the ecosystem. Using an autonomous biophysical observatory, we recorded zooplankton …

Despite concerns about rapid changes in Arctic Ocean physical forcing and ecosystem
function, quantitative knowledge and time series are scarce. The number of reliable physical …

The oceans cover the majority of the Earth's surface; they influence our climate and provide
a valuable source of food to billions of people. Yet despite its fundamental impact on our …

Several recent lines of evidence indicate that the polar night is key to understanding Arctic
marine ecosystems. First, the polar night is not a period void of biological activity even …
