Even during the coldest 750,000 years, the Arctic Ocean had open water and sustained life thanks to seasonal sea ice. “Our ...

Understanding Arctic Ocean's carbon cycle Date: May 21, 2012 Source: Woods Hole Oceanographic Institution Summary: Scientists have conducted a new study to measure levels of carbon at various ...

For years, scientists have debated whether a giant thick ice shelf once covered the entire Arctic Ocean during the coldest ...

In the short term, this creates something of a nutrient injection that jump starts the cycle of life in the ocean. But this April saw a record loss of sea ice across the Arctic.

Today’s Arctic sea ice is more likely to resemble a snow-covered parking lot than the chaotic ice blocks Nansen saw. Two years of tanking summer sea ice—in 2005 and 2007—exposed the dark ...

WITH a hibernation period of up to 100 million years, bacteria discovered on the Arctic sea floor may have longest life cycle of any known organism. Casey Hubert from the Geosciences Group at ...

Arctic ice melt is setting stage for severe winters Date: June 6, 2012 Source: Cornell University Summary: A dramatic melt-off of Arctic sea ice due to climate change is hitting closer to home ...

Recent research by an international team, involving the University of Cape Town (UCT), investigated how a future, warmer Arctic could impact the algae that live in sea ice—and form the base of ...

Sea ice both sequesters plastic from the ocean through its freeze/melt cycle and collects the pollution from above as it is deposited by wind currents. In turn, that sea ice contamination likely ...

The authors suggest that climate change will increasingly affect the Arctic Ocean's nitrogen cycle. More frequent Arctic wildfires will mean greater carbon and nitrogen emissions. Rising ocean CO 2 ...
