Making wastewater less acidic could help the ocean capture more carbon

Altering wastewater released into the ocean could help store carbon stockphoto-graf / Alamy Reducing the acidity of the huge volumes of wastewater discharged into the oceans could be a relatively straightforward way to remove carbon dioxide from the atmosphere and slow climate change. But early tests have spurred controversy over potential environmental consequences. Ming Li … Read more

Bus-sized European satellite crashes to Earth over Pacific Ocean

A dead European satellite fell back to Earth today, bringing an end to its nearly 30-year life in space. The European Space Agency’s (ESA) European Remote Sensing 2 (ERS-2) satellite reentered Earth’s atmosphere at 12:15 EST (1715 GMT) over the Pacific Ocean. The fall ended a nearly 13-year deorbiting campaign that began with 66 engine … Read more

Saturn’s ocean moon Titan may not be able to support life after all

Titan’s underground ocean, and similar oceans inside other icy moons in the outer solar system, may lack the organic chemistry necessary for life, according to new astrobiological research. Titan is Saturn‘s largest moon, and the second largest moon in the entire solar system. It’s famous for being shrouded in a smog of petrochemicals and for … Read more

Greenland Is Literally Rising From The Ocean as It Loses Its Fringe of Glaciers : ScienceAlert

In a mocking fluke of physics, Greenland – one of the main sources of meltwater flooding Earth’s shores – is actually rising faster than the rising oceans. The elevating bedrock is gradually birthing new land in Greenland’s sea including small islands and skerries, like Uunartoq Qeqertaq. Translating as ‘warming island’, this new 13 kilometer (8 … Read more

If the Atlantic Ocean Loses Circulation, What Happens Next?

The following essay is reprinted with permission from The Conversation, an online publication covering the latest research. Superstorms, abrupt climate shifts and New York City frozen in ice. That’s how the blockbuster Hollywood movie “The Day After Tomorrow” depicted an abrupt shutdown of the Atlantic Ocean’s circulation and the catastrophic consequences. While Hollywood’s vision was … Read more

It’s Confirmed. A Major Atlantic Ocean Current Is Verging on Collapse. : ScienceAlert

Last year a concerning study suggested one of Earth’s major ocean currents is racing towards collapse. Unfortunately, new data now backs that up. “The temperature, sea level and precipitation changes will severely affect society, and the climate shifts are unstoppable on human time scales,” the authors of the latest study warn in an article for … Read more

First Look at Asteroid Hints It’s a Fragment of a Lost Ocean World : ScienceAlert

NASA scientists are just getting started in their analysis of fragments brought back from the Bennu asteroid, and the early indications are that the material it contains originated from an ancient ocean world. That assumption is based on the phosphate crust detected on the asteroid. The calcium and magnesium-rich phosphate mineral has never been seen … Read more

The Genetic Secret of Giant Ocean Creatures Is Finally Revealed : ScienceAlert

The large size variation among cetacean species, including dolphins, whales, and porpoises, is largely explained by the activity of specific gene regions, according to a recent study by scientists from Brazil’s University of Campinas Institute of Biology (IB-UNICAMP). Blue whales (Balaenoptera musculus), for example, can grow up to a giant 30 meters (98 feet) long … Read more

The Tectonic Plate Under The Pacific Ocean Is Being Torn Apart, Scientists Reveal : ScienceAlert

While it’s the reigning theory now, the road to acceptance was long and bumpy for plate tectonics, which describes how large portions of Earth’s crust slide, grind, rise and sink ever so slowly across its sludgy mantle. But even now, more than half a century after it was given the scientific tick of approval, the … Read more

NASA’s Asteroid Samples May Come from a Long-Lost Ocean World

Scientists are now inspecting snagged, bagged and tagged bits and pieces from asteroid Bennu, the cosmic mother lode delivered by NASA’s Origins, Spectral Interpretation, Resource Identification and Security — Regolith Explorer mission. Known in acronymic astro-speak as OSIRIS-REx, that seven-year-long voyage brought home the goods via a sample return canister that came to full stop … Read more
