Abstract: The temporal variability of the six terms of the energy balance equation for a slab of ice 3 m thick is calculated based on 45 yr of surface meteorological observations from the drifting ice stations of the former Soviet ...

Abstract: Recent observations of summer Arctic sea ice over the satellite era show that record or near-record lows for the ice extent occurred in the years 2002?05. To determine the physical processes contributing to these changes ...

Abstract: Ice concentration is a critical parameter of the polar marine environment because of the large effect sea ice has on the surface albedo and heat exchange between the atmosphere and the ocean. Simulations of the energy ...

Abstract: Model simulations of Arctic sea ice and ocean systems are used to determine the major spatial and temporal modes of variability in the ice thickness. A coupled ice?ocean model is forced with daily NCEP?NCAR reanalysis ...

Abstract: A new Lagrangian sea ice model for the Arctic Ocean has been developed to accommodate the assimilation of integral measures of ice displacement over periods of days or weeks. The model is a two-layer (thick ice and open ...

Abstract: NASA's RADARSAT Geophysical Processor System (RGPS) uses sequential synthetic aperture radar (SAR) images to track the trajectories of some 30 000 points on the Arctic sea ice for periods of up to 6 months. Much of the ...

Abstract: The surface temperature of arctic sea ice is estimated using the infrared channels of the Advanced Very High Revolution Radiometer (AVHRR) on satellites NOAA-10 and NOAA-11. Temperature statistics are analyzed for 478 cells ...

Abstract: The seasonal cycle of surface albedo of sea ice in the Arctic is estimated from measurements made with the Advanced Very High Resolution Radiometer (AVHRR) on the polar-orbiting satellites NOAA-10 and NOAA-11. The albedos ...

Abstract: The minimum of Arctic sea ice extent in the summer of 2007 was unprecedented in the historical record. A coupled ice?ocean model is used to determine the state of the ice and ocean over the past 29 yr to investigate the ...
