Just a quick note to keep everyone updated on activities onboard the JR. The last several cores have come up less than perfect, showing signs of problems with the bit or the material we're drilling into.

Exp 350: JR Casing Record!

On May 9th, 2014 the JOIDES Resolution set a new record for it’s deepest set casing, beating the old record by 19 meters (leg 186 hole 1151B)!!! The Siem offshore crew set casing down to 1,087 meters below sea floor (mbsf), that’s about 0.7 miles of casing!

This was our one chance to see the moonpool open, and the camera in action.
