High pressure is a defining feature of marine sediments and a major factor influencing biogeochemical processes, the deep biosphere, and gas-hydrate deposits. However, the considerable technical challenges of recovering, handling, and analyzing sediment cores under pressure limit the detailed investigation of the impact of pressure on marine sediment processes. Here we describe recent developments in high-pressure coring, handling, and analysis. In particular, we provide an update on a further development of the European hydrate autoclave coring equipment (HYACE) coring system during the recent Development of the HYACE Tools in New Tests on Hydrates (HYACINTH) project. The two high-pressure coring...

Natural Gas Hydrates—Energy Resource Potential and Associated Geologic Hazards
In September 2004, the American Association of Petroleum Geologists (AAPG) convened a Hedberg Research Conference in Vancouver, British Columbia, Canada titled "Natural Gas Hydrates: Energy Resource Potential and Associated Geologic Hazards." As a continuation of the Hedberg Research Conference in Vancouver, the conveners of the conference and the editors of this Memoir have worked with more than 150 authors and coauthors to prepare this Memoir on gas hydrates. This publication follows the goals of the Hedberg conference; however, the contents of this Memoir were expanded to include all aspects of gas hydrates in nature. This Memoir contains 39 individual contributions, ranging from long topical summaries to shorter focused research papers. This Memoir has been published in two parts, with digital versions of all the complete research papers included on the enclosed CD. The hardcopy portion of the Memoir includes abstracts and several key figures for each of the contributions along with a complete copy of a gas hydrate technical review. The digital portion of this Memoir has been organized into a series of topical sections consisting of review articles, marine gas hydrate papers, and gas hydrate laboratory and modeling studies. Because of the rapidly emerging worldwide interest in gas hydrates, this comprehensive treatise on the geology of gas hydrates will be valuable to both the gas hydrate research community and exploration/development geologists working in arctic and deep marine environments.
