Chief Scientists: Bill Winters, Charlie Paull, MBARI. Data (vaneshear, penetrometer, torvane, pistoncore, gravitycore) of field activity 04020 (K-1-04-NA) in Norwegian Sea, North Atlantic from 08/29/2004 to 09/11/2004, http://walrus.wr.usgs.gov/infobank/k/k104na/html/k-1-04-na.meta.html. These data and information are intended for science researchers, students from elementary through college, policy makers, and general public. Equipment Used - vaneshear penetrometer torvane pistoncore gravitycore Notes - Geotechnical-related devices and supplies provided by USGS WH Geotech lab (vane shear machine, pocket penetrometer, Torvane). Some supplies provided by USGS WH Chem Lab. Jumbo piston corer, Giant gravity corer, Multi-sensor Track. Scientists from the U.S. Geological Survey s Coastal and Marine Geology program participated in a joint cruise with the Monterey Bay Aquarium Research Institute (MBARI) and the Woods Hole Oceanographic Institute (WHOI) aboard the RV Knorr. The National Science Foundation funded the 14-day cruise to investigate the characteristics of sediment surrounding and within the massive Storegga submarine slide as a precursor to potential drill sites of the Integrated Ocean Drilling Program (IODP). The slide, located on the Mid-Norwegian margin, is one of the largest known mass-wasting events encompassing a movement of approximately 5,600 km3 of material, with a headwall scarp 300 km in length with a down slope movement of over 800 km. It is thought the current extent of the slide may actually be the result of at least three different events beginning 50,000 years ago to as recent as 6,000 years ago. Evidence suggests that one part of the slide caused a tsunami that impacted parts of Norway and Scotland. Bottom Simulating Reflectors (BSR), indicative of gas-hydrate containing sediment overlying gas-charged sediment, have been found in seismic-reflection records from the slide area. This leads to speculation that hydrate dissociation, which releases gas molecules from trapped hydrogen-bonded cages and increases pore pressure, may have contributed to the slide. The objective of the cruise was to estimate the amount of gas still left within sediment under the slide and compare it to the amount of gas in the surrounding regions. This information is to be used in determining the mechanism that induced the slide as well as proved insight into the present conditions of surrounding sediment. Representatives from a number of organizations participated in the cruise.
