      Well, I have never been to the Mariana Trench (although some colleagues of mine recently have been there). The areas of the ocean I have been studying so far are mostly along the so-called continental margins, so the area of sea floor adjacent to the land masses, in about 1000 to 4000 m water depth. Right now, we are drilling a hole in 4200 m water depth, which is the deepest I have done so far. And, in 2008 I joined a cruise to the Arctic Ocean, and we took rock samples from Gakkel Ridge, which is a so-called mid-oceanic ridge where new sea floor is produced by magmatic activity. That was pretty cool, volcanoes under the sea!
