A team of scientists in the United Kingdom and the United States has warned that the native fauna and unique ecology of the Southern Ocean, the vast body of water that surrounds the Antarctic continent, is under threat from human activity. Their study is published this week in the peer-reviewed journal Annals of the New York Academy of Sciences. "Although  Antarctica is still the most pristine environment on Earth, its marine ecosystems are being degraded through the introduction of...

By studying the tolerance of marine invertebrates to a wide range of temperature and pressure, scientists are beginning to understand how shallow-water species could have colonized the ocean depths. Scientists believe that climate changes at various at various times during Earth's history caused extinctions of creatures living at bathyal (1,000"“4,000 meters) and abyssal (>4,000 m) depths. These extinctions were apparently followed by re-colonization of the deep sea by shallow-water...

Scientists are unraveling the environmental changes that took place around the Arctic during an exceptional episode of ancient global warming. Newly published results from a high-resolution study of sediments collected on Spitsbergen represent a significant contribution to this endeavor. The study was led by Dr Ian Harding and Prof John Marshall of the University of Southampton's School of Ocean and Earth Science (SOES), based at the National Oceanography Centre, Southampton. Around 56...

Southampton researchers have estimated that  sea-level rose by an average of about 1 meter per century at the end of the last Ice Age, interrupted by rapid "Ëœjumps' during which it rose by up to 2.5 meters per century. The findings, published in Global and Planetary Change, will help unravel the responses of ocean circulation and climate to large inputs of ice-sheet meltwater to the world ocean. Global sea level rose by a total of more than 120 meters as the vast ice sheets of...

The Earth is constantly manufacturing new crust, spewing molten magma up along undersea ridges at the boundaries of tectonic plates. The process is critical to the planet's metabolism, including the cycle of underwater life and the delicate balance of carbon in the ocean and atmosphere. Now, scientists at the Woods Hole Oceanographic Institution (WHOI) have observed ocean crust forming in an entirely unexpected way"”one that may influence those cycles of life and carbon and, in turn,...

Researchers at the University of Bristol reveal today in the journal Nature that they have developed a seismological "Ëœspeed gun' for the inside of the Earth. Using this technique they will be able to measure the way the Earth's deep interior slowly moves around.  This mantle motion is what controls the location of our continents and oceans, and where the tectonic plates collide to shake the surface we live on. For 2,900 km (1800 miles) beneath our feet, the Earth is made of...

Scientists in Southampton, UK, and Ulm and Karlsruhe in Germany have shown that a variant form of a fluorescent protein (FP) originally isolated from a reef coral has excellent properties as a marker protein for super-resolution microscopy in live cells. Their findings have been published online by Nature Methods and will appear in print in the upcoming August issue of that journal. Fluorescent proteins produced by a range of marine animals glow with a rainbow of colors, adding to the visual...

Earth could be as much as 70 million years younger than scientists originally believed, according to a new study which claims that it could have taken the planet 100 million years to reach its current size instead of the widely believed 30 million years. Dr. John Rudge, a research fellow at the University of Cambridge's Trinity College, along with an international team of experts, compared geochemical information originally found in the Earth's mantle and compared it to the same material from...
