Lost and Found: Geologists 'Resurrect' Missing Tectonic Plate

A team of geologists believes they have found the lost plate known as Resurrection in northern Canada by using existing mantle tomography ...

Microbial Diversity Below Seafloor Is as Rich as on Earth's Surface

For the first time, researchers have mapped the biological diversity of marine sediment, one of Earth's largest global biomes. The research team discovered that microbial diversity in the dark, ...

Depths of the Weddell Sea Are Warming Five Times Faster Than Elsewhere

Port Engineers Need Guidance Incorporating Sea Level Rise Into Construction Designs

A survey of maritime infrastructure engineers found that the rising sea level is often not factored into designs of ports, breakwaters, fishing piers and other coastal ...

The Deep Sea Is Slowly Warming

New research reveals temperatures in the deep sea fluctuate more than scientists previously thought and a warming trend is now detectable at the bottom of the ...

Study First to Tally Biomass from Oceanic Plastic Debris Using Visualization Method

Scientists examined cell abundances, size, cellular carbon mass, and how photosynthetic cells differ on polymeric and glass substrates over time, exploring nanoparticle generation from plastic like ...

The findings of new research go against previous thinking around the damage caused by pot fishing to the ...

Sea Star's Ability to Clone Itself May Empower This Mystery Globetrotter

The identity of wild cloning sea star larvae has been a mystery since they were first documented in the Caribbean. The most commonly collected cloning species was thought to belong to the ...

Darwin's Theory About Coral Reef Atolls Is Fatally Flawed

Charles Darwin's 1842 theory about the formation of ring-shaped reefs, called atolls, is incorrect, but 'it's so beautiful, so simple and pleasing' that it still appears in ...

Australian Valley a 'Natural Laboratory' to Test Carbon Sequestration Theory

An idea to enhance natural carbon capture from olivine weathering has never been tested at scale. Geoscientists have proposed the Tweed Valley as a laboratory and gained some interesting initial ...

Ice Melt Projections May Underestimate Antarctic Contribution to Sea Level Rise

Fluctuations in the weather can have a significant impact on melting Antarctic ice, and models that do not include this factor can underestimate the global impact of sea level rise, according to ...

Future Ocean Conditions Could Cause Significant Physical Changes in Marine Mussels

Scientists showed increased temperature and acidification of our oceans over the next century could have a range of effects on an economically important marine ...

The Colorado River's Water Supply Is Predictable Owing to Long-Term Ocean Memory

A team of scientists at Utah State University has developed a new tool to forecast drought and water flow in the Colorado River several years in advance. Although the river's headwaters are in ...

Deep-Seabed Mining Lastingly Disrupts the Seafloor Food Web

Deep-seabed mining is considered a way to address the increasing need of rare metals. However, the environmental impacts are considered to be substantial but remain largely unknown and clear ...

Polar Ice, Atmospheric Water Vapor Biggest Drivers of Variation Among Climate Models

Researchers have found varying projections on global warming trends put forth by climate change scientists can be explained by differing models' predictions regarding ice loss and atmospheric ...

Broken Promises: Almost 80 Percent of Threatened Species Lack Sufficient Protection

A failure by governments to deliver on commitments under a global nature conservation treaty, the Convention on Biological Diversity, could have devastating effects. The warning comes after a ...

Sea-Level Rise Projections Can Improve With State-of-the-Art Model

Projections of potentially dramatic sea-level rise from ice-sheet melting in Antarctica have been wide-ranging, but a Rutgers-led team has created a model that enables improved projections and could ...

Climate Change Responsible for Record Sea Temperature Levels

Global warming is driving an unprecedented rise in sea temperatures including in the Mediterranean, according to a major new ...

Ice Discharge in the North Pacific Set Off Series of Climate Events During Last Ice Age

Repeated catastrophic ice discharges from western North America into the North Pacific contributed to, and perhaps triggered, hemispheric-scale changes in the Earth's climate during the last ice ...

Marine Heatwaves Can Strengthen Hurricanes

Oceanographers have found that a hurricane can be considerably strengthened in the Gulf of Mexico through the compounding effects of two extreme weather events. This process could continue in the ...

How the Humboldt Squid's Genetic Past and Present Can Secure Its Future

Marine biologists studying the genetic structure of the Humboldt squid population found it is vulnerable to overfishing by fleets on its migration ...

Vessel Noise Present Year-Round at Cordell Bank National Marine Sanctuary

The environment in the Cordell Bank National Marine Sanctuary off the coast of San Francisco is not a refuge from the noise generated by ship traffic, the first underwater marine acoustic study of ...
