the Arctic assume sea ice is approximately 2m thicker in winter than in summer. Melting sea ice requires approximately 3 ×10^5J/kg. How much heat in Jm^−2is required to melt 1m of sea ice? If all that heat is provided during the three month period June-August, what is the average summer heating rate of Arctic sea ice (in Wm^−2)? Remember a Watt is a Joule per second and also that the density of sea ice is approximately 1000 kgm^−3.
