Impact Craters Under the Sea The interests of research scientists range widely, as exemplified by today's talk by Dr. Dallas Abbott. Much of her work has investigated the thermal history of the earth, and the manner in which heat transport through the crust and upper mantle influences geological processes, both ancient and present-day. But during the course of such investigations, she noticed evidence that the intensity of mantle plumes (e.g. Hawaii) might be the result of meteorite and other objects crashing into the Earth's oceans. Dr. Abbott will share some of this evidence, describe the techniques she uses to explore these problems, and discuss where future investigations may lead in our knowledge of Earth's past and future.
