The last 24 hours was pretty frustrating, because we were trying to get 10-3/4" casing into a hole drilled into basaltic crust. We got the casing about 320 m into the hole, but could not get it in the last 16 m to land it and latch it in. After trying to get the casing in for about 12 hours, we pulled it back out, shortened it, and now we are going back in to the hole.

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. Some of the last core contained lots of drilling mud, which looked like chocolate milk, not a good sign.

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!
But what is casing?
