Ice mission and extreme camping to verify ESA's CryoSat satellite
While camping may appeal to some, scientists recently took the pastime to punishing limits. Enduring the bitter Arctic cold out on the sea ice, they were part of a major international effort to ensure ESA's ...
Three-decade decline in reflectivity of Arctic sea ice
The reflectivity of Arctic sea ice, or albedo, regulates the solar radiation balance. A diminishing albedo affects the melt rate of Arctic sea ice.
