The seismotectonics of western Skagerrak
The seismically active Skagerrak region in the border area between Denmark and Norway has traditionally been associated with uncertain earthquake locations due to the limited station coverage in the region. A new seismic ...
Rock physics interpolation Used for velocity modeling of chalks: Ontong Java plateau example
(Bentham Open, 2010)
Chalks are pelagic carbonate sediments that are deposited in deep-water environments. Their elastic behaviour is controlled by a combination of depositional conditions and subsequent diagenesis. In this paper, we ...
Paleoclimate changes inferred from stable isotopes and magnetic properties of organic-rich lake sediments in Arctic Norway
Stable isotope measures in organic matter are frequently used as indicators of past climate change. Although such analyses can provide valuable information, there is considerable uncertainty associated with studies of ...
Crustal structure of the ultra-slow spreading Knipovich Ridge, North Atlantic, along a presumed ridge segment center
A combined ocean bottom seismometer, multichannel seismic reflection and gravity study has been carried out along the spreading direction of the Knipovich Ridge over a topographic high that defines a segment center. ...
Norwegian margin outer shelf cracking: a consequence of climate-induced gas hydrate dissociation?
A series of en echelon cracks run nearly parallel to the outer shelf edge of the mid-Norwegian margin. The features can be followed in a *60-km-long and *5-km-wide zone in which up to 10-m-deep cracks developed in the ...
Reconnaissance report and preliminary ground motion simulation of the 12 May 2008 Wenchuan earthquake
The Mw = 8.0Wenchuan earthquake of May 12, 2008, caused destruction over a wide area. The earthquake cost more than 69,000 lives and the damage is reported to have left more than 5 million people homeless. It is estimated ...
The chalk depositional system in the Central Graben – concepts of regional geology, sedimentology and stratigraphy
(The University of Bergen, 2011-12-08)
Improved quantitative calibration of rock physics models
(Geological Society, 2011-11)
In reservoir characterization, rock-physics models provide the link between seismic observables (density, compressional and shear wavespeeds) and reservoir parameters such as porosity, lithology and fluid saturation. ...
Seafloor expression and shallow structure of a surfacing fold-and-thrust system: an example from Isfjorden, West Spitsbergen
(Norwegian Polar Institute, 2012)
A detailed map of the structure of the West Spitsbergen Fold-and-Thrust Belt in the shallow part of the Isfjorden area, Spitsbergen, is presented. The map was constructed from a new dense grid of 2D multichannel reflection ...
Estimation of elastic moduli of mixed porous clay composites
We have developed a procedure for estimating the effective elastic properties of various mixtures of smectite and kaolinite over a range of confining pressures, based on the individual effective elastic properties of pure ...
