Lab experiments question popular measure of ancient ocean temperatures

Understanding the planet's history is crucial if we are to predict its future. While some records are preserved in ice cores or tree rings,...

Big data maps world’s ocean floor

Scientists from the University of Sydney's School of Geosciences have led the creation of the world's first digital map of the seafloor's geology. It is...

Seafloor hot springs a significant source of iron in the oceans

At the bottom of the sea, volcanic and magmatic forces create hot springs that spew super-heated water into the deep sea. The hot, acidic...

Exceptional view of deep Arctic Ocean methane seeps

Close to 30,000 high definition images of the deep Arctic Ocean floor were captured on a recent research cruise. This gives researchers insight into...

Accelerated warming of continental shelf off northeast coast of U.S.

A couple of unexplained large scale changes in the waters off the northeast coast of the U.S. have oceanographers perplexed: an accelerated rate of...

UW’s Deborah Kelley publishes atlas of seafloor volcanoes and deep-ocean life

A University of Washington oceanographer has helped create the first full-color photographic atlas of the ocean floor. "Discovering the Deep: A Photographic Atlas of...

Surprise from the deep ocean

New complex microorganisms discovered as closest relatives of complex organisms Archaea belong together with Bacteria to the first organisms that emerged on Earth. These microorganisms...

Ocean currents disturb methane-eating bacteria

Offshore the Svalbard archipelago, methane gas is seeping out of the seabed at the depths of several hundred meters. These cold seeps are a...

Natural oil dispersion mechanism found for deep-ocean blowout

A first-of-its-kind study observed how oil droplets are formed and measured their size under high pressure. They further simulated how the atomized oil spewing...

New evidence shows carbon’s importance to ocean life’s survival 252 million...

A new study led by scientists with The University of Texas at Arlington demonstrates for the first time how elemental carbon became an important...

Massive study is first to explore historical ocean response to abrupt...

A 30-foot-long core sample of Pacific Ocean seafloor is changing what we know about ocean resiliency in the face of rapidly changing climate. A...

No limit to life in sediment of ocean’s deadest region

An international team of scientists led by a University of Rhode Island oceanographer has found oxygen and oxygen-breathing microbes all the way through the...

Solving carbon mysteries of the deep ocean

Understanding how oceans absorb and cycle carbon is crucial to understanding its role in climate change. For approximately 50 years, scientists have known there...

Mapping seascapes in the deep ocean

Researchers at the National Oceanography Centre (NOC) have developed a new, automated method for classifying hundreds of kilometres of the deep sea floor, in...

Carbon release from ocean helped end the Ice Ageoc

A release of carbon dioxide (CO2) from the deep ocean helped bring an end to the last Ice Age, according to new collaborative research...

Waves in the deep

Acoustic-gravity waves—a special type of sound wave that can cut through the deep ocean at the speed of sound—can be generated by underwater earthquakes,...

Deep ocean a source of dissolved iron in Central Pacific

A new study led by scientists at the Woods Hole Oceanographic Institution (WHOI) points to the deep ocean as a major source of dissolved...

Scientists use ocean waves to monitor offshore oil and gas fields

A technology developed by Stanford scientists for passively probing the seafloor using weak seismic waves generated by the ocean could revolutionize offshore oil and...

Smothered oceans: Extreme oxygen loss in oceans accompanied past global climate...

Seafloor sediment cores reveal abrupt, extensive loss of oxygen in the ocean when ice sheets melted roughly 10,000-17,000 years ago, according to a study...
