UK's deep sea mountain life filmed. 3 August 2014Last updated at 21:36 ET By Victoria Gill Science reporter, BBC News Marine biologist Professor J Murray Roberts describes the life found on the slopes of a mountain a kilometre beneath the sea surface Scientists have sent a remotely operated vehicle to film one of the UK's three undersea mountains, known as seamounts.
The Hebrides Terrace Seamount, off the west coast of Scotland, is higher than Ben Nevis, but its peak is 1,000m beneath the surface. Prof J Murray Roberts, from Heriot-Watt University, and his colleagues filmed more than 100 species on its slopes. They published their findings in the open access journal Scientific Reports.

Icy cold, pitch black and with crushing pressures - the deepest part of the ocean is one of the most hostile places on the planet.
Only three explorers have made the epic journey there: 11km (seven miles) down to the bottom of the Pacific Ocean's Mariana Trench. As a new wave of deep-sea exploration begins, take a look at the mysterious world that they will be plunging into. Pressure Test: Diving 100m down. A 13-year-old eagle huntress in Mongolia. A photographer who snapped what could be the world's only girl hunting with a golden eagle says watching her work was an amazing sight.
Most children, Asher Svidensky says, are a little intimidated by golden eagles. Kazakh boys in western Mongolia start learning how to use the huge birds to hunt for foxes and hares at the age of 13, when the eagles sit heavily on their undeveloped arms. Svidensky, a photographer and travel writer, shot five boys learning the skill as well as the girl, Ashol-Pan. "To see her with the eagle was amazing," he recalls.

A dirty, $10 diamond with a prize inside has helped reveal that there are vast quantities of water stored deep inside the Earth.
The diamond formed in the "transition zone" around 410 to 660 kilometres below our planet's surface. Analysis of a mineral grain trapped inside it suggests that it came from surroundings that were about one per cent water, report researchers led by University of Alberta geochemist Graham Pearson. They published their findings online in the journal Nature today. If the sample is representative of that part of the deep Earth, the amount of water there could be "about the same as the mass of all the world’s oceans combined," wrote Hans Keppler, a geophysicist at the University of Bayreuth in Germany, in an analysis article. That, in turn, changes our understanding of the way water cycles through our planet, and has implications for the way tectonic plates and volcanoes behave, Pearson notes.

But the population was eradicated in the 1920s, leaving the wilderness wolf-free for seven decades. In 1995, however, wolves were reintroduced to Yellowstone; this gave biologists a unique opportunity to study what happens when a top predator returns to an ecosystem. They were brought in to manage the rising elk population, which had been overgrazing much of the park, but their effect went far beyond that. Pinaleno Mountains. The Pinaleño Mountains, or the Pinal Mountains, are a remote mountain range in southeastern Arizona.
They have over 7,000 feet (2,100 m) of vertical relief, more than any other range in the state. Pakistan earthquake: How did it create a 'sudden island'? - CBC News - Latest Canada, World, Entertainment and Business News. Cartographers might have to put another island on the map after Tuesday's massive earthquake created a new island five kilometres off the southern coast of Pakistan, in the Arabian Sea near Gwadar area.
"It's not a common way for islands to be created," says Andrew Miall, a geology professor at the University of Toronto. "But vertical movement of the crust is really common, and it just so happens that, in this case, the crust was very near the surface of the water. " Residents of Gwadar, Pakistan, scramble over a new 30 metre long "instant island" created in the wake of Tuesday's 7.7 magnitude earthquake. Authorities are warning them to keep off the structure as it is leaking methane gas. (Associated Press) Ancient oxygen discovery shakes up history of life on Earth - Technology & Science. Oxygen appeared in the Earth’s atmosphere up to 700 million years earlier than thought, according to a study led by a B.C. scientist, suggesting that revisions need to be made to current theories about how life evolved on Earth.
Up until now, scientists thought photosynthesis — the ability of living things such as algae and plants to harvest energy from the sun — first evolved in single-celled organisms about 2.7 billion years ago. Because oxygen is produced during photosynthesis, early photosynthetic organisms are thought to have given rise to the Great Oxygenation Event, also known as the Great Oxidation, about 2.3 billion years ago.
The incident was thought to be the first time the atmosphere began accumulating significant amounts of oxygen. That is significant because complex multicellular organisms such as humans require an oxygen-rich atmosphere to survive. Animated guide: Hurricanes.

East Antarctic ice sheet 'vulnerable' to temperature changes. 29 August 2013Last updated at 06:04 ET By Matt McGrath Environment correspondent, BBC News The researchers looked at the ebb and flow of huge glaciers like this one in the Transantarctic Mountains as it enters the Ross Ice Shelf The world's thickest ice sheet may be at greater risk from variations in the climate than previously believed.
Scientists found that glaciers on the East Antarctic Ice Sheet (EAIS) advance and retreat in synch with changes in temperature. Since it contains enough water to raise global sea levels by over 50m, there is an urgent need to study the threat the researchers said. The research has been published in the journal Nature.
