CU Boulder ice experts report: Arctic sea ice at lowest maximum for second consecutive year

Arctic sea ice was at a record low maximum extent for the second straight year, according to scientists at the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder and NASA. "I've never see such a warm, crazy winter in the Arctic,” said NSIDC director Mark Serreze. “The heat was relentless." Air temperatures over the Arctic Ocean for the months of December, January, and February were 2 to 6 degrees Celsius (4 to 11 degrees Fahrenheit) above average in nearly every region. Sea ice extent over the Arctic Ocean averaged 14.52 million square kilometers (5.607 million … [Read more...]

NSIDC recovers rescued data and reveals sea ice secrets (video)

50 years ago, NASA launched Nimbus to study Earth from space. Now, experts at the National Snow and Ice Data Center (part of CIRES), are recovering valuable data and images from old, long-lost film, and expanding their understanding of sea ice in the Arctic and Antarctic. When NASA launched Nimbus-1 50 years ago, the agency’s key goals were to test instruments that could capture images of clouds and other meteorological features. The Nimbus satellites made such excellent observations, NASA eventually handed over key technologies to the National Oceanic and Atmospheric Administration … [Read more...]

Seasonal Arctic summer ice extent still hard to forecast, NSIDC study says

The following is an excerpt from the National Snow & Ice Data Center. Read the entire press release at http://nsidc.org/news/press/2014_seasonalseaice_PR.html. Will next year’s summer Arctic ice extent be high or low? Can ship captains plan on navigating the famed Northwest Passage—a direct shipping route from Europe to Asia across the Arctic Ocean—to save on time and fuel? A new study says year-to-year forecasts of the Arctic’s summer ice extent are not yet reliable. Scientists at the National Snow and Ice Data Center (NSIDC), University College London, University of New Hampshire and … [Read more...]
