Researchers at the University of Southampton have conducted the most detailed spatial analysis to date of storm surges along the coast of the UK and Ireland. The oceanographers found that coastlines in the north of the Irish Sea experience the longest and largest surges, while those occurring around the southwest coast of England have the ...

The movement of carbon between the atmosphere, oceans and continents — the carbon cycle — is a fundamental process that regulates Earth’s climate. Some factors, like volcanic eruptions or human activity, emit carbon dioxide into the atmosphere. Others, such as forests and oceans, absorb that CO2. In a well-regulated system, the right amount of CO2 ...

A new map showing the bed of Lake Wānaka in “incredible detail” will help scientists work out the lake’s potential for earthquakes and tsunami, Niwa says. The work was done after an active fault was found under the lake three years ago. Lake Wānaka is thought to be at risk of a tsunami-like event due ...
