SEISMIC REFLECTION BLANK ZONES IN THE ULLEUNG BASIN, OFFSHORE KOREA, ASSOCIATED WITH HIGH CONCENTRATIONS OF GAS HYDRATE

Autor: Stoian, Iulia, Park, Keun-Pil, Yoo, Dong-Geun, Haacke, R. Ross, Hyndman, Roy D., Riedel, Michael, Spence, George D.

It has recently been recognized that abundant gas hydrates occur in localized zones of upwelling fluids, with concentrations much higher than in regional distributions associated with bottomsimulating reflectors (BSRs). We report a study of multi-cha

SEISMIC STRUCTURE, GAS-HYDRATE CONCENTRATIONS, AND SLUMPING ALONG THE IODP X311 TRANSECT ON THE N. CASCADIA MARGIN

Autor: Lopez, Caroll, He, Tao, Dash, Ranjan, Hyndman, Roy D., Spence, George D.

On the lower continental slope off Vancouver Island near scientific ocean drilling IODP Site U1326, traveltime modeling along several ocean bottom seismograph (OBS) profiles shows anomalous high velocities of about 2.0 km/s at 70 - 100 m depth (compa

HYDRATE STUDIES OF NORTHERN CASCADIA MARGIN OFF VANCOUVER ISLAND: A REFERENCE SOURCE

Autor: Riedel, Michael, Hyndman, Roy D., Spence, George D.

This article provides a comprehensive reference list to the extensive studies of marine natural gas hydrate surveys and studies on the northern Cascadian margin of Western Canada. The references are divided into each of the major study methods, surve

Seismic structure across the active subduction zone of western Canada

Autor: Spence, George Daniel

The Vancouver Island Seismic Project (VISP) was conducted in 1980 to study the structure of the subducting oceanic Juan de Fuca plate and the overriding continental America plate. The principal seismic refraction line (line I) was a 350 km onshore-of

Gravity and seismic studies in the southern Rocky Mountain trench

Autor: Spence, George D.

as one of three explanations of a prominenttine delay in the 6.5 km/s branch of their seismic refraction survey in the Rocky Mountain Trench, Eennett et al (1975) suggested a high-angle crustal fault crossing the trench near Radium. If the density co
