Document Summary

Objects appear to shift to the south west when looking down at north pole. Ekman spiras produce eddies (circular ows of water and bigger eddies (gryes) that move as a mass of water across the ocean. Ekman spirals move water offshore when deep colder water moves onshore to replace the surface water. called upwelling. Ekman spirals move warm surface water onshore when surface water sinks! called downwelling. Input - solar energy - sun is only energy source. Rule : lower seasonal contrast -> warmer winters (more snow) and cooler summers (less melt) Lighter oxygen evaporates more easily from oceans -> oceans become heavy oxygen enriched. Heavy oxygen precipitous more easily -> rain returns to heavy oxygen to surface and cloud is further enriched in heavy oxygen. During glaciation light oxygen is trapped in ice -> oceans are enriched in heavy oxygen. Measuring clime change (did not go over assumptions: sea oor sediment.
