... and field tests were carried out to investigate the feasibility of the proposed test method. The test results demonstrated that the percussion method was effective for driving a CPT probe equipped with a tubular sampler. Furthermore, clogging should be prevented at the tip of the sampler for still higher...

.... The sea trials have been carried out in January, August and December 2007. We challenged 9,760-meter depth that was the deepest part of Izu- Ogasawara Trench. And ABISMO recorded 9,707-meter dive. Furthermore, we succeeded in sediment sampling of the sea-bed at water depth 9,760 m by a core sampler...
