According to 25 international researchers who collaborated on a first-of-its-kind study, frozen land beneath rising sea levels currently traps 60 billion tons of methane and 560 billion tons of organic carbon. Little is known about the frozen sediment and soil — called submarine permafrost
Hunger in the Arctic prompts focus on causes, not symptoms
The communities of Nunatsiavut in Northern Labrador, Canada, similar to other communities across Inuit Nunangat, the homeland of Inuit, are plagued by excessive food insecurity rates, which are estimated to be five times the level of food insecurity measured for households in Canada.
Epic Arctic Mission Ends
The German icebreaker Polarstern returned home after being frozen near the top of the world as part of the Multidisciplinary Drifting Observatory for the Study of Arctic Climate, or MOSAiC program, to study all aspects of the Arctic system.
Coldest Northern Hemisphere temperature, first recorded by UW–Madison, officially confirmed
Nearly 30 years after recording a temperature of minus 93.2 degrees Fahrenheit (minus 69.6 Celsius) in Greenland, the measurement has been verified by the World Meteorological Organization as the coldest recorded temperature in the Northern Hemisphere. The measurement was first recorded by a University of Wisconsin–Madison Antarctic Meteorological Research Center Automatic Weather Station in December 1991.
Bedrock drilling project to unlock Greenland Ice Sheet’s secrets
The GreenDrill team aims to unearth new details about the history of the Greenland Ice Sheet. The data could improve predictions of how much global sea levels will rise in the 21st century as ice sheets shrink, researchers say.
Like Humans, Beluga Whales Form Social Networks Beyond Family Ties
A groundbreaking study is the first to analyze the relationship between group behaviors, group type, group dynamics, and kinship of beluga whales in 10 locations across the Arctic. Results show that not only do beluga whales regularly interact with close kin, including close maternal kin, they also frequently associate with more distantly related and unrelated individuals. Findings will improve the understanding of why some species are social, how individuals learn from group members and how animal cultures emerge.
UNH Researchers Find Wildfires Can Alter Arctic Watersheds for 50 Years
Climate change has contributed to the increase in the number of wildfires in the Arctic where it can dramatically shift stream chemistry and potentially harm both ecosystems and humans. Researchers at the University of New Hampshire have found that some aftereffects, like decreased carbon and increased nitrogen, can last up to five decades and could have major implications on vital waterways.
A Rapidly Changing Arctic
A new study by researchers at Woods Hole Oceanographic Institution (WHOI) and their international colleagues found that freshwater runoff from rivers and continental shelf sediments are bringing significant quantities of carbon and trace elements into parts of the Arctic Ocean via the Transpolar Drift—a major surface current that moves water from Siberia across the North Pole to the North Atlantic Ocean.
How Stable is Deep Ocean Circulation in Warmer Climate?
If circulation of deep waters in the Atlantic stops or slows due to climate change, it could cause cooling in northern North America and Europe – a scenario that has occurred during past cold glacial periods. Now, a Rutgers coauthored study suggests that short-term disruptions of deep ocean circulation occurred during warm interglacial periods in the last 450,000 years, and may happen again.
