Suppose now that the ice is tranparent enough so that some sunlight makes it rhough. Let's see how that would change the ice thickness. a) calculate the globally averageed solar flux incident on Earth's surface during the Neoproterozoic glaciation (0.6 Ga) S=1302.066 W/m^2 b)the solar flux at the equator is about 20% higher than the global average value. suppose that 10% of this incident sunlight makes it through the ice. How thin must the ice layer be in order to conduct this heat back out so that the water temperature remains constant? F=lambda x change in temperature/change in thickness of the ice layer. F is the geothermal heat flux. Current geothermal heat flux is about 0.09 W/m^2 c) is the ice thickness calculated in part b consistent with the assumption that it would transmit 10% of the sunlight through it?
