Both frozen carbon dioxide and organic matter are important forms of soil carbon
The team, led by PI Deborah Huntzinger and co-PIs Michelle Mack and Victor Leshyk of Northern Arizona University, will create Polar Explorer, a tool that uses virtual reality to transport students to the Arctic.
As melting sea ice brings more ships through the Northwest Passage, new research shows that Canada must prepare for the costs and consequences of an Arctic oil spill
Slow-moving arctic soils form patterns that, from a distance, resemble those found in common fluids such as drips in paint and birthday cake icing.
WASHINGTON (April 16, 2021) — For Earth Day 2021, President Joe Biden has invited 40 world leaders to take part in a virtual summit to focus on solutions for climate change and other environmental problems. The George Washington University has experts who…
Overfishing likely did not cause the Atlantic cod, an iconic species, to evolve genetically and mature earlier, according to a study led by Rutgers University and the University of Oslo – the first of its kind – with major implications for ocean conservation.
A study conducted by the Cornell Lab of Ornithology’s Center for Conservation Bioacoustics aims to understand how resilient bearded seals can be to changes in ambient underwater noise.
ORNL story tips: Modeling COVID, permafrost lost and taking the heat
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
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.
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.
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.
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.
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.
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 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.
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.
The movement of sea ice between Arctic countries is expected to significantly increase this century, raising the risk of more widely transporting pollutants like microplastics and oil, according to new research from CU Boulder.
As the ice sheet covering most of Greenland retreats, Florida State University researchers are studying the newly revealed landscape to understand its role in the carbon cycle.
Protecting the permafrost after a record fire season
A major new IIASA report highlights new and emerging policy trends in the Arctic, a region on the front lines of climate change, geopolitics, and global governance.
New Brunswick, N.J. (Feb. 3, 2020) – Rutgers University–New Brunswick experts are available for interviews on the generally mild January weather and low snowfall in New Jersey so far this winter. “According to preliminary data, January 2020 in New Jersey was the…
The prevailing view has been that more leads are associated with more low-level clouds during winter. But University of Utah atmospheric scientists noticed something strange in their study of these leads: when lead occurrence was greater, there were fewer, not more clouds.
Geologists, examining the desolate Vavilov ice cap on the northern fringe of Siberia in the Arctic Circle, have for the first time observed rapid ice loss from an improbable new river of ice, according to new research in the journal Geophysical Research Letters.
The Arctic region is heating up faster than any other place on Earth, and as more and more sea ice is lost every year, we are already feeling the impacts. IIASA researchers explored strategies for cooling down the oceans in a world without this important cooling mechanism.
MOSAiC, the largest polar expedition of all time, will produce demanding quantities of data. ORNL staff in the field and the lab collect, store and process it to share with collaborators around the world.
The German icebreaker RV Polarstern is scheduled to set sail today from Tromsø, Norway, for a 13-month journey to wherever the sea ice takes it. In a week or so, the ship will get locked into the Arctic ice and drift with the ice floes for a year so that scientists can gather unprecedented data about the Arctic climate.
The research team is comprised of Tom Ballinger, Assistant Professor in the Department of Geography at Texas State University, Dagmar Budikova, Department of Geography, Geology and the Environment, Illinois State University, and Trent W. Ford, Department of Geography and Environmental…
