    Ice types, albedos and impurity content are characterized for the ablation zone of the Greenland ice sheet in Kronprinz Christians Land (808 N, 248 W). Along this ice margin the width of the ablation zone is only about 8 km. The emergence and melting...

    These data give estimates of black carbon (BC) mixing ratios from samples of snow or melting sea ice gathered by ourselves or by volunteers, mostly from 2006 to 2009 but with some data from earlier years. Almost all samples were collected in the spring...

    This is data for helicopter infrared photometry regarding aerial observations. A crucial element of SHEBA is to extend process-oriented observations and models to larger-scales. Local measurements provide data on mass changes, optical properties, and...

    The temporal evolution of the mass balance of different ice categories was monitored at 10 sites that were carefully selected to represent the widest possible range of ice types and conditions. These sites typically consisted of a thermistor string and...

    The presence of particulates in the snow cover and at the ice surface can decrease the spectral albedo of the system at visible wavelengths where absorption by ice and water is small. Because of this, we were concerned that the release and local...

    As part of ice-albedo feedback studies during SHEBA, we measured spectral and wavelength-integrated albedos. Measurements were made at least weekly every 2.5 m along a 200-m survey line from April through October. Initially this line was completely...
