Call for Nomination: D/V CHIKYU Shimokita Shakedown Cruise Back to list
CDEX/JAMSTEC will conduct a shakedown cruise off Shimokita, NE Japan on D/V CHIKYU from August to October 2006. This will be the first riser shakedown cruise for CHIKYU. CHIKYU successfully recovered HPCS (Hydraulic Piston Coring System) cores from two sites off Shimokita last November-December. The HPCS cores collected during this shakedown cruise were processed in the CHIKYU’s laboratories, and the measured data were uploaded into our data management system, J-CORES.

CDEX will conduct more engineering tests, coring tests (HPCS and RCB) and laboratory evaluations during this year’s expedition. We would like to invite several scientists and/or laboratory technical personnel from IODP member countries to assist CDEX to provide suggestions for our laboratory set-up, facility readiness, manuals, core processing procedure, IT environment, etc. CDEX will accept nominations for our shakedown cruises through the IODP Program Management Offices (J-DESC, USSAC, ESSAC & MOST).

♦ Duration: Seven sessions of 10 days. ( Please note that number of Legs might be changed depending on status of shakedown training. In addition, we will use a helicopter to embark and disembark on CHIKYU, so please note that the duration may change depending on weather conditions. )
