We have fully processed all HPCS and ESCS cores, and are progressing rapidly through cores 1R-12R. RCB coring has recommenced, and processing, description, and sampling of cores continues.

Received cores 1R-12R, recovery is limited in accretionary prism material. Recovery between 0 and 61 percent. Attempting to use 5 m advance during drilling to minimize loss of recovery. Time permitting, this tactic will be used in the softer materials in the accretionary prism material. XCT measurements, IW and MBIO whole round cores collected, MSCL and ThermCon measurements underway. Cores 1H-16H have been split, described, sampled, and stored. Cores 17H – 12R are in progress.
