Wouldn't surprise me if lots jumped ship from archaeology to geo, its a sinking ship (even more thn the titanic). I was always based at Drumond st, close to cafe lucano (good for vegan cake)! if you see a newish lecturer, greek, who has likes insects, she was fomerly archaeology!
I am basically doing climate change in Roman times (that is as simple as I can make it sound without boring folks with excess details)!
