Image: Antarctic research base Concordia

The Franco-Italian Antarctic research base of Concordia sits 1670 km from the South Pole. On the plateau some 3200 m high, the air is so thin that inhabitants live in a permanent state of hypoxia – lack of oxygen. The closest ...

The Copernicus Sentinel-3A satellite takes us over the Atlantic Ocean close to Spain and Portugal where the sky not only features clouds but also criss-cross tracks from maritime vessels.

Polar vortex defies climate change in the Southeast

Overwhelming scientific evidence has demonstrated that our planet is getting warmer due to climate change, yet parts of the eastern U.S. are actually getting cooler. According to a Dartmouth-led study in Geophysical Research ...

How seafloor weathering drives the slow carbon cycle

A previously unknown connection between geological atmospheric carbon dioxide cycles and the fluctuating capacity of the ocean crust to store carbon dioxide has been uncovered by two geoscientists from the University of Sydney.

Tracking ocean salinity from space using colour

Measuring salinity at the ocean's surface is important for tracking global ocean circulation as well as local ecosystem health. A research team from Universiti Malaysia Terengganu have proposed a new method to measure sea ...

Deep-sea fish use hydrothermal vents to incubate eggs

Some deep-sea skates—cartilaginous fish related to rays and sharks—use volcanic heat emitted at hydrothermal vents to incubate their eggs, according to a new study in the journal Scientific Reports. Because deep-sea skates ...
