34 million years ago the warm 'greenhouse climate' of the dinosaur age ended and the colder 'icehouse climate' of today commenced. Antarctica glaciated first and geological data imply that the Atlantic meridional overturning circulation, the global ocean conveyor belt of heat and nutrients that today helps keep Europe warm, also started at this time. Why exactly, has remained a mystery.
He solved a 127-year-old physics problem on paper and proved that off-centred boat wakes could exist. Five years later, laboratory experiments proved him right.
Scientists may have uncovered how sea-surface temperature patterns influence the number, strength and distributions of April tornado formation in the south-central region of the United States known as 'Tornado Alley.' Their results underscore how shifting climate patterns potentially affect tornado formation within seasons, which could help reduce fatalities and
Injecting carbon dioxide (CO2) deep below the seabed could be an important strategy for mitigating climate change, according to some experts. However, scientists need a reliable way to monitor such sites for leakage of the greenhouse gas. Now, researchers reporting in ACS' journal Environmental Science & Technology have studied natural sources of CO2 release off the coast of Italy, using what they learned to develop models that could be applied to future storage sites.
A team of researchers led by Griffith University has mapped out how much waves are likely to change around the globe under climate change and found that if we can limit warming to 2 degrees, signals of wave climate change are likely to stay within the range of natural climate variability.
New research provides evidence of the formation and abundance of abiotic methane -- methane formed by chemical reactions that don't involve organic matter -- on Earth and shows how the gases could have a similar origin on other planets and moons, even those no longer home to liquid water.
A globally important ocean algae is mysteriously scarce in one of the most productive regions of the Atlantic Ocean, according to a new paper. A massive dataset has revealed patterns in the regions where Atlantic coccolithophores live, illuminating the inner workings of the ocean carbon cycle and raising new questions.
The Maritime Archaeological Trust has discovered a new 8,000 year old structure 11 metres below sea level on the Isle of Wight. It is the most intact, wooden Middle Stone Age structure ever found in the UK.
MIT researchers have developed a battery-free underwater communication system that uses near-zero power to transmit sensor data. The system could be used to monitor sea temperatures to study climate change and track marine life over long periods -- and even sample waters on distant planets. They are presenting the system at the SIGCOMM conference this week, in a paper that has won the conference's 'best paper' award.
When will we see significant changes in the ocean due to climate change? A new study finds that some changes are noticeable already, while others will take up to a century.
