In the Arctic, ringed seals and other ice-associated pinnipeds aren’t merely the polar bear’s prey. They’re its raison d’être. Fossil and DNA records suggest that the white bears began ...

While an increasing percentage of Arctic sea ice melts each summer, a portion of the Arctic Ocean remains covered in ice year-round. New research on ice cores sampled from this multi-year ice show ...

"Rapid changes in river nitrogen chemistry could completely transform how these marine ecosystems function," according to a university statement. From 2003 to 2023, Ruyle and his team measured ...

As the sea ice melts in the Arctic—which is warming substantially faster than the global average—the food webs living in these icy waters are in peril. Food webs are huge, complex systems made ...

These algae, along with algal species that live in the open ocean, form the base of the Arctic food web. And they are an important food source even for species that don’t live under the ice, a ...

Researchers at Scripps Institution of Oceanography at the University of California San Diego and colleagues analyzed Arctic Ocean satellite data from a 19-year period and found that the amount of ...

Over the past few years, we have been constructing the first quantitative food web for a High Arctic community. Currently expanding into the whole flora and fauna of North East Greenland, the study ...

Arctic study shows key marine food web species at risk from increasing carbon dioxide Date: December 2, 2013 Source: University of Exeter Summary: A research expedition to the Arctic, as part of ...

The Arctic Ocean is so cold that only a handful of fish and marine mammals can survive there. Subsurface temperatures range from 37.4 degrees Fahrenheit on a warm summer day to 28.76 degrees, the ...

Arctic cod represent a most critical nexus point in the Arctic food web, and their place in the ecosystem has so far been well protected by both human and natural systems.
