Distinguishing Pacific and Atlantic Contributions to the Arctic
A semi-conservative tracer combining nitrate and dissolved oxygen is more accurate than traditional tracers in distinguishing between Atlantic and Pacific water mass contributions to the Arctic.
Atmospheric Gravity Wave Science in the Polar Regions
A joint special issue explores the potential of collaboration to help understand atmospheric gravity waves in the Polar Regions and their effect on global circulation.
Largest Delta Plain in Earth’s History Discovered in Arctic
If this Triassic period delta existed today, its footprint would equal about 1% of all land on Earth.
Modern Warming Is Undoing Millennia of Arctic Ice Cover
Plants and rocks at the edges of glaciers have been entombed in ice for more than 40,000 years. Modern warming, unmatched in 115,000 years, is now uncovering these landscapes.
The Future of Scientific Drilling in the North Pacific and Arctic
International Ocean Discovery Program Workshop; Mount Hood, Oregon, 25–27 September 2018
Arctic Undergoing Most Unprecedented Transition in Human History
The Arctic Report Card, released by the National Oceanic and Atmospheric Administration, outlines vast changes taking place in the Arctic region. Here are some major findings.
Autumn in the Arctic
With refreezing in the western Arctic Ocean shifting later into the autumn, field research on changing air-ocean-ice interactions suggests that the Arctic is shifting to a more seasonal system.
New Paths for Plankton in Warming Arctic?
Water flowing from the Pacific to the Atlantic could find new shortcuts, enabling plankton to survive the trip through the cold polar region.
The Upside to a “Bad” Ozone Precursor
In Sweden’s wet heathland, scientists see how a sensitive ecosystem adapts to rising global temperatures.
