Climate changes in the northern and southern hemispheres are linked by a phenomenon by which the oceans react to changes on either side of the planet. A research team from the Universitat Autònoma de Barcelona and the Cardiff University has shown for the first time that ocean circulation in the southern hemisphere has, in the past, adapted to sudden changes in the north. The research published today in Science will enable more accurate forecasts to be made on how the oceans will react to climate cha

Harbor Branch Biomedical Expedition to include first submersible exploration of remote Cay Sal Bank

On Monday, the Harbor Branch drug discovery group will begin a 2-week expedition to explore the Straits of Florida in search of organisms that produce chemicals with the potential to cure diseases such as cancer and Alzheimer’s. The work will include the first submersible exploration of the remote Cay Sal Bank, which encompasses a number of small, uninhabited islands 30 mile

Several companies are extracting black gold – petroleum – from the North Sea. But scientists are questioning this activity and asking if this activity has environmental consequences. By law, these companies are obliged to carry out annual analyses.

At the request of the companies, a number of researchers at the Science Faculty of the University of the Basque Country have analysed what type of contaminants are released as a result of extraction of crude oil in the North Sea a

Engineers at the University of Liverpool are conducting research to reduce the threat posed to homes and property by ocean waves.

Approximately 10% of people in England live in areas at risk from flooding or coastal erosion. In the absence of man-made defences such as sea walls, the annual damage to property and roads in these areas would exceed £2 billion.

Terry Hedges, from the University’s Department of Civil Engineering has produced a computer model to assess volum

Tilt is a 100,000-year planetary pacemaker

Scientists have long debated what causes glacial/interglacial cycles, which have occurred most recently at intervals of about 100,000 years. A new study reported in the March 24 issue of Nature finds that these glacial cycles are paced by variations in the tilt of Earth’s axis, and that glaciations end when Earth’s tilt is large.

With more than 30 explanations proposed for these glacial cycles, researchers at the Woods Hole Oc

Predicting when large earthquakes might occur may be a step closer to reality, thanks to a new study of undersea earthquakes in the eastern Pacific Ocean. The study, reported in today’s Nature, is the first to suggest that small seismic shocks or foreshocks preceding a major earthquake can be used in some cases to predict the main tremors.

Scientists from the Woods Hole Oceanographic Institution (WHOI) and the University of Southern California (USC) report that some types of larg
