Ocean Drilling Program Leg 135 Preliminary Report
Leg 135 of the Ocean Drilling Program drilled and cored eight sites across the Lau Basin and adjacent Tonga Ridge to study the geological evolution of a backarc basin and adjacent oceanic arc and forearc. Six sites (Sites 834, 835, 836, 837, 838, and 839) were drilled within the Lau Basin, each within smaller and narrower (<10 km) north-south fault basins and collectively representing a broad e...
متن کاملOcean Drilling Program Leg 184 Preliminary Report South China Sea
The Asian monsoon system is a major component of both regional and global climate. Evolution of monsoonal climates in southern Asia is linked to the growth of the HimalayanTibetan orogen, the opening and closing of marginal seas, and changes in global climate. The location of the South China Sea (SCS) between East Asia and the “maritime continent” is ideal to record the paleoceanographic respon...
متن کاملOcean Drilling Program Leg 204 Scientific Prospectus Drilling Gas Hydrates on Hydrate Ridge, Cascadia
During Ocean Drilling Program (ODP) Leg 204, we will drill a transect of sites through the gas hydrate stability zone on the southern part of Hydrate Ridge on the Cascadia accretionary margin offshore Oregon. Massive hydrates are present at the seafloor there, and high-resolution threedimensional seismic data indicate a complicated subsurface plumbing system. The transect will cover two distinc...
متن کاملAddressing Geohazards Through Ocean Drilling
Natural geohazards, such as earthquakes, volcanic eruptions, landslides, and volcanic collapse, are of immediate societal concern. In an oceanic setting (Fig. 1), all are capable of generating tsunami that threaten coastal zones at distances of many thousands of kilometers. This power and its effects were forcefully shown by the giant earthquake (� w 9.2) and tsunami of 26 December 2004 off t...
متن کاملThirty thousand years of vegetation development and climate change in Angola (Ocean Drilling Program Site 1078)
ODP Site 1078 situated under the coast of Angola provides the first record of the vegetation history for Angola. The upper 11 m of the core covers the past 30 thousand years, which has been analysed palynologically in decadal to centennial resolution. Alkenone sea surface temperature estimates were analysed in centennial resolution. We studied sea surface temperatures and vegetation development...
