Explicitly modelled deep-time tidal dissipation and its implication for Lunar history

摘要: Abstract Dissipation of tidal energy causes the Moon to recede from Earth. The currently measured rate recession implies that age Lunar orbit is 1500 My old, but known be 4500 old. Consequently, it has been proposed dissipation was weaker in Earth's past, explicit numerical calculations are missing for such long time intervals. Here, first time, model simulations linked climate output conducted a range paleogeographic configurations over last 252 My. We find present poor guide past terms dissipation: total rates most were far below levels. This allows us quantify reduced resent fraction lunar history, and lower refinement orbitally-derived models by inserting complete additional precession cycle.
