Abstract : HYACE, an EU MAST III Project (EU MAS3 CT97 0102) HYACE is the acronym for gas hydrate autoclave coring equipment system. The project started in December of 1997 and it shall last until December 2000. Eight partners from six European countries constitute the HYACE Consortium. It is coordinated by Technische Universität Berlin, Fachgebiet Maritime Technik. Development and prototype testing of innovative, downhole actuated and downhole controlled autoclave coring systems constitute the central activities of the project. They were developed, designed and tested to sample a wide range of marine sediments at downhole conditions and bring the cores onboard while maintaining as many downhole parameters as possible. Particular targets are sediments on the deepwater covered continental slopes containing gas hydrates. Sampling tools include push, percussion and rotary corers. The corers are downhole driven by the drilling fluid and downhole motors instead of top drives onboard the scientific drillship. The main scientific goal of the project is to contribute to systematic ground truthing of a necessarily ephemeral phenomenon of growing global significance: assessing quantitatively volatile gas hydrates in their natural deepsea environment. This must be achieved by obtaining validated parameters of the in-situ and downhole conditions to the largest possible extent. Complementary measurements while coring are furthermore important. Temperature and pressure monitoring had been selected upon request by the geoscientific community as the
