Energy and Mass Balance Observations of the land-ice-
We present results from a comprehensive field study carried out near Barrow, Alaska designed to characterize local- to intermediate-scale sea-ice processes in the arctic coastal zone of central importance to the annual cycle and evolution of the coastal sea ice. Included in this are the behavior of...
