Mobile protected areas needed to protect biodiversity in the high seas
As the United Nations rewrites the laws of the high seas, the new document should anticipate emerging technologies that allow protected areas to move as animals migrate or adapt to climate change.

In death of dinosaurs, it was all about the asteroid -- not volcanoes
Volcanic activity did not play a direct role in the mass extinction event that killed the dinosaurs, according to an international team of researchers. It was all about the asteroid.

Slow-motion interplate slip detected in the Nankai Trough near Japan
Researchers used a Global Navigation Satellite System-Acoustic ranging combination technique to detect signals due to slow slip events in the Nankai Trough with seafloor deformations of 5 cm or more and durations on the order of one year. These events generally occurred on the shallow sides of regions with strong interplate coupling and represent variations in interplate friction conditions, which may help simulate the occurrence of megathrust earthquakes originating from this subduction zone and contribute earthquake disaster prevention.

'The blob,' food supply squeeze to blame for largest seabird die-off
When nearly one million common murres died at sea and washed ashore from California to Alaska in 2015 and 2016, it was unprecedented -- both for murres, and across all bird species worldwide. Scientists blame an unexpected squeeze on the ecosystem's food supply, brought on by a severe and long-lasting marine heat wave known as 'the blob.'

New assessment of gas locked in ice in European waters
A study has mapped several sites in Europe containing gas hydrate - a relatively clean fuel which could help bridge the gap between fossil fuels and renewables.

Deep-sea mining's impact on microbes
The essential roles that microbes play in deep-sea ecosystems are at risk from the potential environmental impacts of mining, a new article reports. The study reviews what is known about microbes in these environments and assesses how mining could impact their important environmental roles.

How nodules stay on top at the bottom of the sea
Rare metallic elements found in clumps on the deep-ocean floor mysteriously remain uncovered despite the shifting sands and sediment many leagues under the sea. Scientists now think they know why, and it could have important implications for mining these metals while preserving the strange fauna at the bottom of the ocean.

Climate gas budgets highly overestimate methane discharge from Arctic Ocean
There is a huge seasonal variability in methane seeps in the Arctic Ocean, according to a new article.

Cracks in Arctic sea ice turn low clouds on and off
The prevailing view has been that more leads are associated with more low-level clouds during winter. But an atmospheric scientists noticed something strange in their study of these leads: when lead occurrence was greater, there were fewer, not more clouds.

Scientists use ancient marine fossils to unravel long-standing climate puzzle
Scientists have shed new light on the Earth's climate behavior during the last known period of global warming over 14 million years ago.

Sea-ice-free Arctic makes permafrost vulnerable to thawing
New research provides evidence from Siberian caves suggesting that summer sea ice in the Arctic Ocean plays an essential role in stabilizing permafrost and its large store of carbon.

Gelatinous zooplankton makes an important contribution to marine carbon transport
Barely visible to the naked eye, gelatinous zooplankton is an important part of the marine ecosystem. In addition, the small organisms also transport large quantities of carbon into deeper layers of the ocean, thus making an important contribution to marine carbon transport.

Antarctic waters: Warmer with more acidity and less oxygen
The increased freshwater from melting Antarctic ice sheets plus increased wind has reduced the amount of oxygen in the Southern Ocean and made it more acidic and warmer, according to new research.

North Atlantic Current may cease temporarily in the next century
The North Atlantic Current transports warm water from the Gulf of Mexico towards Europe, providing much of north-western Europe with a relatively mild climate. However, scientists suspect that meltwater from Greenland and excessive rainfall could interfere with this ocean current. Simulations showed that there is a 15 percent likelihood that there will be a temporary change in the current in the next 100 years.

Where do baby sea turtles go? New research technique may provide answers
A team of researchers created a first-of-its-kind computer model that tracks where sea turtle hatchlings go after they leave Florida's shores, giving scientists a new tool to figure out where young turtles spend their 'lost years.'

Ancient Mediterranean seawall first known defense against sea level rise and it failed
Ancient Neolithic villagers on the Carmel Coast in Israel built a seawall to protect their settlement against rising sea levels in the Mediterranean, revealing humanity's struggle against rising oceans and flooding stretches back thousands of years.
