Ocean circulation, ice melt and increasing tourism could all be contributing to Arctic microplastics
Scientists measured microplastic concentrations in the highly productive Barents Sea and suggest that ocean circulation, ice melt, tourism, inadequate waste management, shipping and fishing are all likely contributors. Numerous studies have shown that global microplastic quantities in the marine environment…
Researchers reveal mechanism triggering Arctic daily warming
Prof. REN Baohua and his team from the School of Earth and Space Sciences, the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), uncovered the connection between Arctic daily warming and the equator region as well as Atlantic storms.
Scientists unravel evolutionary history of the Arctic flora
A team led by Prof. WANG Wei from the Institute of Botany of the Chinese Academy of Sciences (IBCAS) has unraveled the evolutionary history of the Arctic flora. The study was published in Nature Communications.
Arctic ice algae heavily contaminated with microplastics
The alga Melosira arctica, which grows under Arctic sea ice, contains ten times as many microplastic particles as the surrounding seawater. This concentration at the base of the food web poses a threat to creatures that feed on the algae at the sea surface.
Tastes differ – even among North Atlantic killer whales
Killer whales (also known as orcas) are intelligent predators. While it’s known that killer whales in the Pacific Northwest exploit widely different food types, even within the same region, we know much less about the feeding habits of those found throughout the North Atlantic.
Scientists find iron cycling key to permafrost greenhouse gas emissions
The interaction of elemental iron with the vast stores of carbon locked away in Arctic soils is key to how greenhouse gases are emitted during thawing and should be included in models used to predict Earth’s climate, Oak Ridge National Laboratory scientists found.
Investigating the Dynamics that Reshape Permafrost Environments
Researchers using monitoring data from Alaska permafrost found that vegetation and the snowpack that accumulates in winter control the temperatures below ground and thus the flow of water in the ground. By highlighting the link between above- and belowground properties and processes, these results will help improve scientists’ predictions of how the Arctic interacts with overall climate change.

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.
