The winter lasts about 3.5 earth months, or approximately 10's. Estimate the depth to which these seasonal temperature variations penetrate. To do this, calculate thermal diffusivity, then use the characteristic length for conduction to estimate the depth that seasonal variations penetrate into the ice. If the probe can only drill 2 meters down into the ice, will it drill deep enough to get below seasonal temperature variations?

N The winter lasts about 3.5 earth months, or approximately 10's. Estimate the depth to which these seasonal temperature variations penetrate. To do this, calculate thermal diffusivity, then use the characteristic length for conduction to estimate the depth that seasonal variations penetrate into the ice. If the probe can only drill 2 meters down into the ice, will it drill deep enough to get below seasonal temperature variations? K * = 1/² [ + ] => K= 0.3 w/heil Pc 1000 K2000/²c Length = Krime = 10² Length =√K Time K= Length ² time Length Vlog -10's Length = V1 m² = 1m
