At midnight, the SE-02B hole reached a final depth of 191.64. Full recovery of consolidated tuff core occurred to ~182 m depth. From 182-185 m there was 0.98 m recovered and from 185-188 there was only 0.38 m recovered. This last run had a small section of loosely consolidated, coarse grained dark gravel, and then a nice chunk of fine grained, smooth rock perhaps the seafloor beneath the volcano. Downhole logging with the ICDP team has begun.
