I had a great day: I estimated the temperature of the North Atlantic upper mantle, I had an great meeting on the temperature of Anatolia, I sent our SKS splits to a co-author for publication, and spent 2 hours on a proposal. Tomorrow's a teaching day and I hope it goes as well.
@derek So what was your estimate of the temperature of the North Atlantic upper mantle?
@GeorgeMari It varies by location and depth :). Roughly 700-1200C.
@GeorgeMari parts of it seem to be underlain by a mantle plume, which is a hot upwelling from deeper in the earth.
