Developing a relationship between static Young’s modulus and seismic parameters
(Journal article, 2022-07-19)Mechanical properties of petroleum reservoirs can be determined via static techniques based on laboratory triaxial tests under reservoir conditions. Dynamic approaches represent an alternative in cases where such static ... -
Development of an enhanced CPT system for Dogger Bank
(Chapter, 2022)An enhanced seafloor CPT system has been developed to support completion of the soil investigation campaign for Dogger Bank. This enhanced system has a demonstrable and significant performance increase over standard seafloor ... -
Diagenetic related flat spots within the Paleogene Sotbakken Group in the vicinity of the Senja Ridge, Barents Sea
(Peer reviewed; Journal article, 2019) -
Different mechanisms of Arctic first-year sea-ice ridge consolidation observed during the MOSAiC expedition
(Peer reviewed; Journal article, 2023) -
Differentiating reefal ridges from relict coastal ridges: Lessons from the seismic geomorphologic study of buried Miocene buildups (North West Shelf, Australia)
(Peer reviewed; Journal article, 2023)Linear buildups formed in tropical carbonate environments are often interpreted as bioconstructed reefs. Nevertheless, coastal processes can also form extensive sedimentary ridges exhibiting buildup morphologies. This study ... -
The differentiation of thaws in connection with slushflow occurrences.
(NGI Publication;203, Chapter, 1998)Classification of meteorological conditions accompanying slushflow occurrences is attempted. Days with mean daily air temperature above O°C have been chosen for the analysis. Each day has been described with a set of ... -
Digital Drill Core Models: Structure-from-Motion as a Tool for the Characterisation, Orientation, and Digital Archiving of Drill Core Samples
(Peer reviewed; Journal article, 2020)Structure-from-motion (SfM) photogrammetry enables the cost-effective digital characterisation of seismic- to sub-decimetre-scale geoscientific samples. The technique is commonly used for the characterisation of outcrops, ... -
Direct Simple Shear Tests on Snow and their Relation to Slab Avalanche Formation
(Journal article, 1977)Many slab avalanches can be attributed to shear failure in a weak, thin basal layer at the slab base. A reasonable starting point for evaluation of the conditions prior to fracture is, therefore, an investigation of shear ... -
Direction Estimates for Short‐Period P‐Waves on Three‐Component Stations and Arrays
(Peer reviewed; Journal article, 2023)P‐arrival backazimuth estimates can be crucial in locating poorly constrained seismic events. Correlating short windows of the vertical waveform with corresponding windows of the radial rotation for different backazimuths ... -
Discovery of Holocene ooid shoals in a siliciclastic delta, De Grey River, North West Shelf, Australia
(Peer reviewed; Journal article, 2023)Onshore and offshore site investigations along the dryland tide-dominated De Grey River delta (northwestern Australia) led to the unexpected discovery of the largest yet-known marine ooid shoals in the Indo-Pacific region. ... -
Discussion: Undrained cylindrical cavity expansion in anisotropic critical state soils
(Journal article; Peer reviewed, 2018) -
Dispersion of tsunamis: does it really matter?
(Journal article, 2013)This article focuses on the effect of dispersion in the field of tsunami modeling. Frequency dispersion in the linear long-wave limit is first briefly discussed from a theoretical point of view. A single parameter, denoted ... -
Distribution of PAHs, PCBs, and PCDD/Fs in products from full-scale relevant pyrolysis of diverse contaminated organic waste
(Peer reviewed; Journal article, 2023)Biomass pyrolysis is the anoxic thermal conversion of biomass into a carbon rich, porous solid, often called biochar. This could be a better waste management alternative for contaminated organic wastes than incineration, ... -
The diversities of large slushflows illustrated by selected cases.
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2010)Rapid mass movement of water-saturated snow, usually known as slushflow or slush avalanche, is a major natural hazard in Norway. The destructive forces are larger than those observed from other snow related mass flows of ... -
Drainage conditions around monopiles in sand
(Journal article; Peer reviewed, 2019)Large diameter monopiles are typical foundation solutions for offshore wind turbines. In design of the monopile foundations in sand, it is necessary to understand the drainage conditions of the foundation soil under the ... -
Drifting snow in complex terrain. Comparison of measured snow distribution and simulated wind field.
(Chapter, 2000)Snowdrift in complex terrain can cause significant problems for maintenance of road and railway systems during winter and is a major factor for snow avalanche releases. The location of accumulation and erosion areas is ... -
Drilling 1100-km-long seafloor ridges reveals how palaeoshorelines control carbonate shelf morphologies (North West Shelf, Australia)
(Peer reviewed; Journal article, 2023)The Rowley Shelf, the southern half of the tropical, carbonate-dominated, North West Shelf of Australia, is covered with linear ridges that can be tracked parallel to the coast over 1100 km between the modern coast and the ... -
DUE avalRS: Remote-Sensing Derived Avalanche Inventory Data for Decision Support and Hind-Cast after Avalanche Events
(Chapter, 2010)Each year, snow avalanches hit populated areas and parts of the transport network in the Norwegian mountain regions, leading to loss of lives and the damaging of buildings and infrastructure. We present the results of a ...
