I could have been a part of this: http://news.com.com/Missing+A+huge+chunk+of+Earths+crust/2100-11395_3-6164853.html

Fascinating!

A team of British scientists has set sail on a voyage to examine why a huge chunk of Earth's crust is missing, deep under the Atlantic Ocean--a phenomenon that challenges conventional ideas about how the planet works.

The 20-strong team aims to survey an area some 1.9 to 2.6 miles deep where the mantle--the deep interior of the planet normally covered by a crust miles thick--is exposed on the seafloor.

Experts describe the hole along the Mid-Atlantic Ridge as an "open wound" on the ocean floor that has puzzled scientists for the five or so years that its existence has been known because it defies existing tectonic plate theories of evolution.

"We know so little about it," said Bramley Murton, a senior research scientist at Southampton's National Oceanography Centre.
