Give a marine snail an easy life, and it will take its time drilling into a clam. Put it under competitive stress, and it will look for a faster route. Those changes, scarred into fossils, show that an unknown catastrophe nearly two million years ago changed the competitive balance in the Western Atlantic and the ecosystem has yet to fully recover, according to research published this week in the journal Science.

A team led by University of Maine scientists has reported finding a potential link between changes in solar activity and the Earth’s climate. In a paper due to be published in an upcoming volume of the Annals of Glaciology, Paul Mayewski, director of UMaine’s Climate Change Institute, and 11 colleagues from China, Australia and UMaine describe evidence from ice cores pointing to an association between the waxing and waning of zonal wind strength around Antarctica and a chemical signal

Hurricanes bring temporary relief to Florida reefs smothered by invasive seaweed

In August, Harbor Branch scientists began a new survey of Florida coral reefs expecting to document the devastating spread of harmful seaweed that has been progressing now for several years, but hurricane havoc has instead led the team to a surprising find. With their first survey nearly completed, it appears all reefs in the path of hurricanes Frances and Jeanne have been largely scoured free of

Europe’s coastlines are exposed to risk of pollution. I-MARQ’s prototype Geographical Information System (GIS) delivers detailed information on coastal water quality, helping decision makers shore up defences by taking appropriate action against contamination.

A recent Communication from the European Commission highlights some of the issues the IST-funded i-MARQ project aims to solve: “Our coastal zones are facing serious problems of habitat destruction, water contamination, coast

People in earthquake-prone California often talk about the “Big One,” a devastating quake that many experts say will surely strike the region sometime in the future.

A research team is now working to predict when the big one – and even little ones – might occur. Termed SAFOD (San Andreas Fault Observatory at Depth), the project involves more than 20 researchers from several major universities, labs and government agencies, including the husband-wife team of Fred and Judi Chester

Imagine a lake three times the size of the present-day Lake Ontario breaking through a dam and flooding down the Hudson River Valley past New York City and into the North Atlantic. The results would be catastrophic if it happened today, but it did happen some 13,400 years ago during the retreat of glaciers over North America and may have triggered a brief cooling known as the Intra-Allerod Cold Period.
