In bitter cold regions like northwestern Canada, permafrost has preserved relict ground-ice and vast glacial sedimentary stores in a quasi-stable state. These landscapes therefore retain a high potential for climate-driven transformation, say researchers.

Local weather plays an important part in the retreat of the ice shelves in West Antarctica, according to new research.

Seagrass meadows -- bountiful underwater gardens that nestle close to shore and are the most common coastal ecosystem on Earth -- can reduce bacterial exposure for corals, other sea creatures and humans, according to new research.

Scientists and government officials met at the United Nations today to consider possible solutions to a global problem: how to protect whale species in their most important marine habitats that overlap with shipping lanes vital to the economies of many of…

New research findings explain an Ice Age paradox and add to the mounting evidence that climate change could bring higher seas than most models predict.

The ongoing global change causes rising ocean temperatures and changes the ocean circulation. Therefore less oxygen is dissolved in surface waters and less oxygen is transported into the deep sea. This reduction of oceanic oxygen supply has major conseque…

Based on data from the first ocean sensors deployed under Greenland's Petermann Glacier, researchers report that the floating ice shelf is strongly coupled, or tied, to the ocean below and to the adjacent Nares Strait. Warming temperatures recorded at the…

Cracks in the Greenland Ice Sheet let one of its aquifers drain to the ocean, new NASA research finds. The aquifers, discovered only recently, are unusual in that they trap large amounts of liquid water within the ice sheet. Until now, scientists did not …

The possibility of major climate change in the Atlantic region has long been recognized and has even been the subject of a Hollywood movie: The Day After Tomorrow. To evaluate the risk of such climate change, researchers developed a new algorithm to analy…

Ice loss from Canada's Arctic glaciers has transformed them into a major contributor to sea level change, new research has found. From 2005 to 2015, surface melt off ice caps and glaciers of the Queen Elizabeth Islands grew by an astonishing 900 percent.

As the world continually emits carbon dioxide into the atmosphere, the oceans are taking a hit, absorbing some of it and growing more acidic. Among other effects, scientists have found that coral reefs and oyster hatcheries are deteriorating as a result. …

Last winter's El Niño might have felt weak to residents of Southern California, but it was in fact one of the most powerful climate events of the past 145 years. If such severe El Niño events become more common in the future as some studies …

Crustaceans from the deepest ocean trenches found to contain ten times the level of industrial pollution than the average earthworm, scientists have shown.

Scientists have discovered that tiny marine bacteria can synthesize one of Earth's most abundant sulfur molecules, which affects atmospheric chemistry and potentially climate. This molecule, dimethylsulfoniopropionate is an important nutrient for marine m…

Marine researchers have made sure that their research drones aren't disturbing their research subjects, shows a new report. And they're hoping that others will follow their example to help protect wildlife in the future.

A new study on how ocean currents transport floating marine debris is helping to explain how garbage patches form in the world's oceans. Researchers developed a mathematical model that simulates the motion of small spherical objects floating at the ocean …

The Arctic has a serious litter problem: in just 10 years, the concentration of marine litter at a deep-sea station in the Arctic Ocean has risen 20-fold, according to researchers.

The movements of Earth's tectonic plates shape the face of our planet. The sinking of one plate beneath another causes volcanism and earthquakes. Scientists have been able to drill and investigate the origin of a subduction zone for the first time in 2014…

Sea level in Southeast Asia fluctuated wildly -- and naturally -- more than 6,000 years ago, twice rising nearly two feet in a period of about 200 years, report researchers.

Less than a year after the first research flight kicked off NASA's Oceans Melting Greenland campaign, data from the new program are providing a dramatic increase in knowledge of how Greenland's ice sheet is melting from below.
