Scientists have reconstructed in detail the collapse of the Eurasian ice sheet at the end of the last ice age. The big melt wreaked havoc across the European continent, driving home the original Brexit 10,000 years ago.

Biodiversity losses from deep-sea mining are unavoidable and possibly irrevocable, an international team of scientists, economists and lawyers argue. They say the International Seabed Authority, which is responsible for regulating undersea mining in areas…

In the year 2100, 2 billion people -- about one-fifth of the world's population -- could become climate change refugees due to rising ocean levels. Those who once lived on coastlines will face displacement and resettlement bottlenecks as they seek habitab…

During the last glacial period, within only a few decades the influence of atmospheric CO2 on the North Atlantic circulation resulted in temperature increases of up to 10 degrees Celsius in Greenland -- as indicated by new climate calculations.

There is a clear potential for practical and useful predictions of northwestern European and Arctic climate based on the state of the ocean, new research indicates.
June 20th
Waves deep within the ocean play an important role in establishing ocean circulation, arising when tidal currents oscillate over an uneven ocean bottom. The internal waves generated by this process stir and mix the ocean, bringing cold, deep water to the …

An autonomous underwater vehicle offers promise for advanced marine research use. This will make it possible to conduct detailed studies of the seabed at great depths and track the climate thousands of years back in time, say researchers.

For the first time, researchers have identified what drives the observed differences in the chemical make-up of sea spray particles ejected from the ocean by breaking waves.

Scientists believe they have discovered the reason behind mysterious changes to the climate that saw temperatures fluctuate by up to 15°C within just a few decades during the ice age periods.

Understanding slow-slip earthquakes in subduction zone areas may help researchers understand large earthquakes and the creation of tsunamis, according to researchers who used data from instruments placed on the seafloor and in boreholes east of the Japane…

An area of West Antarctica more than twice the size of California partially melted in 2016 when warm winds forced by an especially strong El Nino blew over the continent.

To understand how human activities are affecting the planet, scientists often study the health of animals in the wild. Now a new study finds that the levels of mercury in some polar bears are declining. But rather than heralding a drop in mercury in the e…

The Science Team of the Canadian Research Icebreaker CCGS Amundsen has cancelled the first leg of the 2017 Expedition due to complications associated with the southward motion of hazardous Arctic sea ice, caused by climate change.

More than five trillion pieces of plastic debris are estimated to be in our oceans, though many are impossible to see with the naked eye.

Paleontologists investigating the sea bed off California have discovered a lost ecosystem that for thousands of years had nurtured communities of scallops and shelled marine organisms called brachiopods. They had died off by the early 20th century, replac…

Researchers have returned from the Philippines with new species discoveries and deeper insights into threatened coral reef ecosystems.

Unlike other species that migrate successfully to escape the wrath of climate change, a new study shows that dispersal may help sustain global Emperor penguin populations for a limited time, but, as sea ice conditions continue to deteriorate, the 54 colon…

The Arctic Ocean was once a gigantic freshwater lake. Only after the land bridge between Greenland and Scotland had submerged far enough did vast quantities of salt water pour in from the Atlantic.

It is only six centimeters long, but it plays a major role in the Antarctic ecosystem: the small crustacean Euphausia superba (Antarctic krill). It's one of the world's most abundant species and the central diet of a number of animals in the Southern Ocea…

Highly protected marine reserves can help mitigate against the impacts of climate change, a study by a team of international scientists has concluded.
