Building New Ways to Think About Arctic Freshwater
A new literature review summarizes the complex role of freshwater in the Arctic and its impact on climate and biogeochemical systems as a whole.
Climate Models Predict Diverse Arctic Ocean Shipping Routes
As ice melts, multiple models yield more detailed route predictions than any single model alone.
Arctic States Nearing Science Cooperation Pact
Negotiations are focusing on removing obstacles to conducting research rather than on setting international scientific priorities. Research priorities among Arctic nations already overlap considerably, according to a U.S. negotiator.
Arctic Tides Drive Water Mixing and Sea Ice Loss
Researchers model ice-ocean interaction to study how tides can influence Arctic Ocean circulation and sea ice volume.
Vanishing Sea Ice Could Trigger More Arctic Precipitation
A promising method for evaluating Arctic precipitation predicts retreating sea ice will increase snow and rainfall in the Arctic and counteract some of global climate change's effects regionally.
Sounding the Northern Seas
A new compilation of underwater terrain provides the most up-to-date mapping of portions of the western Arctic and North Pacific.
Giant Balls of Bacteria Pile Up on Arctic Lake Beds, Ooze Toxin
Researchers have found cyanobacteria colonies as big as softballs thriving unexpectedly on shallow Greenland lake bottoms, exuding liver-damaging microcystin. Locals dubbed them "sea tomatoes."
Arctic Report Card Highlights Profound Regional Changes
The annual assessment focuses on changes to sea ice, snow cover, temperature, and other indicators. Scientists say that changes in the Arctic also affect climate globally.
Ships Bring More Than Cargo to Arctic Waters
A probe of ballast water in ships at an Arctic port finds hitchhiking organisms that polar warming could allow to invade the region's ecosystems in less than 40 years.
