WASHINGTON, June 21, 2011 /PRNewswire-USNewswire/ -- Scientists embark this week from Alaska on the second and final campaign of a NASA field campaign to study how changing conditions in the Arctic affect the ocean's chemistry and ecosystems. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) On June 25, the ICESCAPE mission, or "Impacts of Climate on Ecosystems and Chemistry of the Arctic Pacific Environment," resumes its shipborne investigation of the impacts of climate...

Global temperatures in May were the 10th warmest for any May since 1880, when records began being kept, while the extent of Arctic sea ice was the third smallest for any May on record, the National Oceanic and Atmospheric Administration (NOAA) reported on Thursday. The monthly analysis from NOAA's National Climatic Data Center showed that last month's combined global land and ocean average surface temperature was 59.5F (15.30 Celsius), which is 0.9 F (0.5 C) above the 20th century average of...

Scientists from the U.S., U.K. and Australia have used ice-penetrating radar to create the first high- resolution topographic map of one of the last uncharted regions of Earth, the Aurora Subglacial Basin, an immense ice-buried lowland in East Antarctica larger than Texas. The map reveals some of the largest fjords or ice cut channels on Earth, providing important insights into the history of ice in Antarctica. The data will also help computer modelers improve their simulations of the past...

Research led by Rensselaer Polytechnic Institute scientist finds evidence that early antarctic circumpolar current development impacted global climate Thirty-eight million years ago, tropical jungles thrived in what are now the cornfields of the American Midwest and furry marsupials wandered temperate forests in what is now the frozen Antarctic. The temperature differences of that era, known as the late Eocene, between the equator and Antarctica were only half of what they are today. A debate...

A team of scientists from the University of Sheffield and Bangor University have used a computer climate model to study how freshwater entering the oceans at the end of the penultimate Ice Age 140,000 years ago affected the parts of the ocean currents that control climate. A paper based on the research, co-authored by Professor Grant Bigg, Head of the University of Sheffield's Department of Geography, his PhD student Clare Green, and Dr Mattias Green, a Senior Research fellow at Bangor...

The Earth experienced the seventh warmest April since record keeping began in 1880, as the climate phenomenon La Niña continued to be a significant factor. April's annual Arctic sea ice extent was the fifth smallest since record keeping began in 1979, while the Antarctic sea ice extent was the fourth smallest. The monthly analysis from NOAA's National Climatic Data Center in Asheville, N.C., is part of the suite of climate services NOAA provides government, business and...

The research aircraft Polar 5 of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association returned to Bremerhaven from a six-week expedition in the high Arctic on May 6. Joint flights with aircraft of the European and American space agencies (ESA and NASA) were a novelty in sea ice research. Simultaneous measurements with a large number of sensors on three planes underneath the CryoSat-2 satellite led to unique data records. Furthermore, the international team...

A carefully executed operation to validate data from CryoSat has shown what can be accomplished when ESA, NASA and others join forces to further our understanding of how the fragile polar environment is responding to climate change. In support of ESA's CryoSat ice mission, which was launched a year ago to monitor changes in ice thickness, a grueling validation campaign is being carried out in one of the most inhospitable environments on Earth. The one-month Arctic expedition is a major...

To guarantee ESA's CryoSat mission is delivering the best data possible, scientists have set out on a major expedition to the Arctic "“ part of a collaborative effort between ESA and NASA to gather ice measurements as the satellite orbits above. CryoSat was launched a year ago today to monitor the changes in the thickness of marine ice in the polar oceans and in the vast ice sheets that blanket Greenland and Antarctica. Orbiting closer to the poles than any other satellite and carrying...

The 2011 Arctic sea ice extent maximum that marks the beginning of the melt season appears to be tied for the lowest ever measured by satellites, say scientists at the University of Colorado Boulder's National Snow and Ice Data Center. The CU-Boulder research team believes the lowest annual maximum ice extent of 5,650,000 square miles occurred on March 7. The maximum ice extent was 463,000 square miles below the 1979-2000 average, an area slightly larger than the states of Texas and...

Arctic Ocean

The Arctic Ocean which is located in the Northern Hemisphere and mostly in the Arctic north polar region, is the shallowest and smallest of the world’s five major oceanic divisions. The International Hydrographic Organization recognizes it as an ocean, although, some oceanographers consider it as the Arctic Mediterranean Sea or simply, the Arctic Sea, classifying it a Mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be considered as the northernmost...
