We've Hit Rock Bottom Now!

At approximately 9am this morning, for the first time during this expedition, our drillers reached 1507.1 meters below the seafloor (mbsf) in Hole 1256D.
In December of 2005, Expedition 312 successfully deepened this hard rock hole to 1507.1 mbsf, and ours is the first expedition to return to this site since that time. Now that we have successfully returned to the maximum depth achieved during 312, we can begin preparing to deepen Hole 1256D further -- and to take new core!
