Shipboard Scientist, Maria-Jose Jurado Rodriguez (Spain) is in (real-time) discussion with other scientists by pointing out at the real-time log data from the first NanTroSEIZE LWD hole. >>Expedition 314 Photo Gallery

IODP NanTroSEIZE Stage 1:
Expedition 314: NanTroSEIZE LWD Transect
Weekly Report #2
Date 05/Oct/2007

Preparation for geotechnical coring began on 29 September at Hole C0001B and 30m cores were taken from the seafloor at 2189m water depth on 30 September. Running into the hole with LWD assembly commenced on October 1st. Hole C0001C was spudded in at 19:15. The hole inclination was found to be 6 degrees caused by strong Kuroshio current. Hence the string was pulled out of the hole and moved to new site nearby. Hole C0001D was spudded on 2nd October. To prevent a hole deviation, the drill pipe and bit were jetted 70 m in and rotary drilling began at 30 m/hr rate of penetration. Progress was slowed by tight hole and high torque conditions. Utilized the drilling data of Pilot Hole A, drilling conditions improved and reached 627 meter below seafloor on 4th October.

Final confirmation and practice for the LWD data processing was carried out among four sub-groups scientists with support from the Core-Log-Seismic-Integration staff. The whole science party finished Safety Management System (SMS) lectures, and participated in biweekly Safety Management Meeting. On Hole C0001B pilot cores, X-ray CT, MSCL-W, and Moisture and Density measurements were conducted. Science seminars were held continuously, covering 20 topics. LWD real-time data was monitored while the data processing specialist was working and log data quick check, data distribution and processing procedure were confirmed by scientist's working groups. In Lab area, continued the preparation for the coming coring expeditions, maintenance, instrument setup and rearrangements. Measurements of geo-technical cores were conducted in support of wellsite geologist.
