Long-term river chemistry study reveals how the Arctic is changing

OCEANOGRAPHY
A Florida State University scientist has helped uncover through a multidecadal study how changing water chemistry in Arctic rivers could impact the entire planet. New...

Ozone treaty is delaying first ice-free Arctic summer, shows study

OCEANOGRAPHY
A 1987 global deal to protect the ozone layer is delaying the first ice-free Arctic summer by up to 15 years, new research shows....

From Arctic to Alps, icy exploration expands understanding of global warming

OCEANOGRAPHY
Microalgae in sediments signal what happened in the environment thousands of years ago, illuminating the range of future climate-change impacts. The scientists deployed a heavy-duty...

Scientists save ancient Arctic ice in race to preserve climate history

EARTH
Scientists have succeeded in saving samples of ancient Arctic ice for analysis in a race against time before it melts away due to climate...

World’s biggest cumulative logjam, newly mapped in the Arctic, stores 3.4 million tons of carbon

EARTH
Throughout the Arctic, fallen trees make their way from forests to the ocean by way of rivers. Those logs can stack up as the...

Scientists in Arctic race to preserve ‘ice memory’

EARTH
Scientists camped in the Arctic are set to start drilling to save samples of ancient ice for analysis before the frozen layers melt away...

EXPLAINER: Arctic blast sweeps US, bomb cyclone possible

OCEANOGRAPHY
An arctic blast is bringing extreme cold, heavy snow and intense wind across much of the U.S. this week—just in time for the holidays. The...

Study shows that strongest Arctic cyclone on record led to surprising loss of sea ice

OCEANOGRAPHY
A warming climate is causing a decline in sea ice in the Arctic Ocean, where loss of sea ice has important ecological, economic and...

Scientists discover southward migration of Arctic Ocean species during the last glacial period

EARTH
In order to survive, a species must find the most favorable habitat to pass on its genes. Therefore, learning how species migrated with climate...

For the first time, we can measure the thickness of Arctic sea ice all year round

OCEANOGRAPHY
Using satellites, we are now able to measure ice thickness in the Arctic—even in the summer. This is of great importance for shipping in...

Arctic lakes are vanishing in surprise climate finding

ENVIRONMENT
The Arctic is no stranger to loss. As the region warms nearly four times faster than the rest of the world, glaciers collapse, wildlife...

Research shows need to improve prediction of Arctic melt ponds

OCEANOGRAPHY
