Rare metals crucial to green industries turn out to have a surprising origin. Ancient global climate change and certain kinds of undersea geology drove fish populations to specific locations. As remains of the fish fossilized, they accumulated valuable el…

The Arctic Ocean will take up more carbon dioxide over the 21st century than predicted by most climate models, according to researchers. This additional carbon dioxide causes a distinctly stronger ocean acidification.

Scientists have discovered that the summer sea ice in the Weddell Sea sector of Antarctica has decreased by one million square kilometers -- an area twice the size of Spain -- in the last five years, with implications for the marine ecosystem.

With more accurate modeling data, response teams can better predict the search area grid from the air, and reduce emergency response time when lives are on the line.

New research tapped into a collection of dried, pressed seaweed to understand what the bay was like before the impacts of modern human activity. Researchers used the older algae specimens to extend the Bakun upwelling index back to 1878, 70 years before i…

A study has examined fossil reefs near to the now-submerged Red Sea shorelines that marked prehistoric migratory routes from Africa to Arabia. The findings suggest this coast offered the resources necessary to act as a gateway out of Africa during periods…

Biologists are on a quest to discover more of the still nameless tanaids, specifically in the relatively species-rich but poorly studied tropical Indo-Pacific.

Ice melts in the Arctic Ocean were thought to be drawing large amounts of carbon dioxide out of the atmosphere, acting as a carbon sink and helping to mitigate greenhouse gases. But new research shows that may not be the case in all areas, particularly in…

As oceans absorb more human-made carbon dioxide from the air, a process of ocean acidification occurs that can have a negative impact on marine life. But coastal waterways, such as Chesapeake Bay, can also suffer from low oxygen and acidification. New res…

Even in the most remote regions of the oceans plastic debris can be found. Usually it is impossible to determine how long they have been lying on the seabed. Up to now, this has also hampered attempts to estimate how long plastic degradation might take. S…

The collapse of terrestrial ecosystems during Earth's most deadly mass extinction event was directly responsible for disrupting ocean chemistry, according to new research.

How we account for sand is important for understanding how reefs, atolls and coastal regions will cope with the effects of climate change. Scientists have discovered models for measuring sand were giving incorrect information and have developed more accur…

An international study suggests islands composed of gravel material can evolve in the face of overtopping waves, with sediment from the beach face being transferred to the island's surface.

All the new coupled climate models project that the area of sea ice around Antarctica will decline by 2100, but the amount of loss varies considerably between the emissions scenarios.
June 7th
New research has shown that a shortage of summer nutrients -- a result of our changing climate -- has contributed to a 50% decline in important North East Atlantic plankton over the past 60 years.

Researchers have projected significant changes in the habitat of commercially important American lobster and sea scallops on the Northeast U.S. continental shelf. They used a suite of models to estimate how species will react as waters warm. The researche…

Researchers have used an unmanned aerial system (or drone) to gather data on schooling juvenile Atlantic bluefin tuna in the Gulf of Maine. This pilot study tested whether a drone could keep up with the tuna while also taking photographs that captured phy…

Mangrove trees -- valuable coastal ecosystems found in Florida and other warm climates - won't survive sea-level rise by 2050 if greenhouse gas emissions aren't reduced, according to a new study. Using sediment data from the last 10,000 years, an internat…

250-million-year-old cracks in the seafloor feed greenhouse gas methane into giant craters in the Barents Sea. More than 100 craters, presently expelling enormous amounts of the greenhouse gas into the ocean, are found in the area.

Warming ocean temperatures and acidification drastically reduce the skeletal strength and filter-feeding capacity of glass sponges, according to new research. The findings indicate that ongoing climate change could have serious, irreversible impacts on th…
