This isn’t exactly a convergence topic, but the science is just too cool to miss…from the BBC website:

Scientists are to sail to the mid-Atlantic to examine a massive “open wound” on the Earth’s surface.

Dr Chris MacLeod, from Cardiff University, said the Earth’s crust appeared to be missing across an area of several thousand square kilometres.

The expedition is being logged at a site for teachers and students here. (Image linked from this website).
