Oldest Ice	Permalink

First phase of project to collect 1.5 million years of climate data in Antarctica A team of European scientists heads to East Antarctica this month to locate the oldest ice on Earth. The team is part of an EU-funded research consortium from ten European countries whose aim is to search for a suitable site to drill an ice core to capture 1.5 million years of Earth's climate history. The project, Beyond EPICA - Oldest Ice (BE-OI), will answer important questions about big shifts in the past record of Earth's climate. Read more __________________

Scientists are planning to ship samples of ice to the Antarctic. Scientists are planning to ship ice to the Antarctic. They're afraid that mountain glaciers around the world are melting as a result of climate change and want to store samples of ice in a new vault in the coldest place on Earth. At 4,350m the Col du Dome sits just below the summit of Mont Blanc. Read more __________________

SPICE	Permalink

New project plans to retrieve South Pole ice core beginning in 2014-15 SPICE is targeting a timeline 40,000 years back into the past as part of an initiative called International Partnerships in Ice Core Sciences (IPICS) , which seeks to create a network of ice cores over similar timescales spread across both Antarctica and Greenland. The target of 40,000 years spans the transition from the peak of the last glacial period when ice sheets were at their maximum extent - referred to as the Last Glacial Maximum - to the present warm period called an interglacial.

WAIS Divide team drills historic replicate ice core in West Antarctica A team of scientists and drilling engineers performed the Antarctic equivalent of pulling a rabbit out of the hat deep under the ice sheet in December. They retrieved a one-meter-long ice core from about 3,000 meters down a borehole drilled through the West Antarctic Ice Sheet (WAIS). That in itself isnt unusual. Thousands of meters of ice have been extracted from Antarctica over the last half-century, and are one of the most reliable sources for reconstructing past climate. Read more __________________

Greenland ice	Permalink

Greenland ice may exaggerate magnitude of 13,000-year-old deep freeze Ice samples pulled from nearly a mile below the surface of Greenland glaciers have long served as a historical thermometer, adding temperature data to studies of the local conditions up to the Northern Hemisphere's climate. But the method - comparing the ratio of oxygen isotopes buried as snow fell over millennia - may not be such a straightforward indicator of air temperature. According to a study published today by the Proceedings of the National Academy of Sciences, the Greenland ice core drifts notably from other records of Northern Hemisphere temperatures during the Younger Dryas, a period beginning nearly 13,000 years ago of cooling so abrupt it's believed to be unmatched since. Such periods of speedy cooling and warming are of special interest to climate scientists, who are teasing out the mechanisms of high-speed change to better understand and predict the changes occurring in our own time.

Ice cores	Permalink

Ice cores drilled from the polar ice sheets represent a rare and valuable window on the past. The ice, together with air bubbles locked within it, provides a detailed record of how the climate has changed. This is particularly important in light of concerns about future climate. Also trapped within the ice are tiny ash particles from volcanic eruptions. These provide a unique chronicle of volcanic events, which can help to pinpoint when the climate changed in the past. A new NERC-funded project involving scientists from Swansea University, the University of St Andrews and Aberystwyth University aims to look for these volcanic traces in a new, deep ice core from Greenland.

120,000-year-old Ice Yields Clues to Climate of a Warmer Earth More than a mile of ice core was pulled from the Greenland ice sheet by scientists this summer, setting a new record for single-season deep ice-core drilling. The researchers, from 14 countries and led by the University of Copenhagen, are on a quest to recover ice formed 120,000 years ago, the last time our planet was in a period of warm climate such as the one many scientists think we are now entering.

International Greenland Ice Coring Effort Sets New Drilling Record in 2009 A new international research effort on the Greenland ice sheet with the University of Colorado at Boulder as the lead U.S. institution set a record for single-season deep ice-core drilling this summer, recovering more than a mile of ice core that is expected to help scientists better assess the risks of abrupt climate change in the future. The project, known as the North Greenland Eemian Ice Drilling, or NEEM, is being undertaken by 14 nations and is led by the University of Copenhagen. The goal is to retrieve ice from the last interglacial episode known as the Eemian Period that ended about 120,000 years ago. The period was warmer than today, with less ice in Greenland that led 5 metre higher sea levels than present--conditions similar to those Earth faces as it warms in the coming century and beyond, said CU-Boulder Professor Jim White, who is leading the U.S. research contingent.
