An experiment featuring the largest flotilla of sensors ever deployed in a single area provides new insights into how marine debris, or flotsam, moves on the surface of the ocean. The experiment conducted in the Gulf of Mexico near the site of the Deepwater Horizon oil spill placed hundreds of drifting sensors to observe how

New research, published today in Nature Scientific Reports, not only implies a link between catastrophic volcanic eruptions and landslides, but also suggests that landslides are the trigger. At the heart of Tenerife and standing almost 4 km high, Teide is one of the largest volcanoes on Earth. Over a period of several hundred thousand years, the

Everything on the surface of the Earth rests on massive tectonic plates that resemble a jelly sandwich, with two rigid pieces — the upper crust and the upper mantle — enclosing a gooey middle layer of very hot rocks, which is the lower crust. The plates move ever so slowly around the globe over a

There is an enduring myth that large earthquakes tend to happen during certain phases of the Moon or at certain times during the year. But a new analysis published in Seismological Research Letters confirms that this bit of earthquake lore is incorrect. After matching dates and lunar phases to 204 earthquakes of magnitude 8 or larger, Susan

Increased fluctuations in the path of the North Atlantic jet stream since the 1960s coincide with more extreme weather events in Europe such as heat waves, droughts, wildfires and flooding, reports a University of Arizona-led team. The research is the first reconstruction of historical changes in the North Atlantic jet stream prior to the 20th

Visiting a colleague in Germany in 2012, Boston College Research Professor Paul K. Strother was examining soil samples for pollen, spores, pieces of plants and insect legs – organic debris that might otherwise have been considered “pond scum” when it was trapped in sediment during cataclysmic earth events 200 million years ago. The slides of

Sixty-five million years ago, clouds of ash choked the skies over Earth. Dinosaurs, along with about half of all the species on Earth, staggered and died. But in the seas, a colorful population of marine bivalves–the group including oysters, clams and scallops–soldiered on, tucked into the crevices of ocean floors and shorelines. Though they also

One of the key effects of the end-Permian mass extinction, 252 million years ago, was rapid heating of tropical waters and atmospheres. How this affected life on land has been uncertain until now. In a new study published today, Dr Massimo Bernardi and Professor Mike Benton from the School of Earth Sciences at the University

In a study spanning two decades, a team of researchers led by Colorado State University found declining numbers of soil fauna, nematodes and other animal species in the McMurdo Dry Valleys, one of the world’s driest and coldest deserts. This discovery is attributed to climate change, which has triggered melting and thawing of ice in

For the first time, scientists have shown through direct satellite observations of the ozone hole that levels of ozone-destroying chlorine are declining, resulting in less ozone depletion. Measurements show that the decline in chlorine, resulting from an international ban on chlorine-containing manmade chemicals called chlorofluorocarbons (CFCs), has resulted in about 20 percent less ozone depletion
