Landslide displacement prediction based on wavelet transform and long short-term memory neural network
(Chapter, 2019)The prediction of landslide displacement is a key component of an early warning system to mitigate landslide risk. Most of the models for landslide displacement prediction are static models. Yet, landslides move dynamically. ... -
Offshore Wind Turbine Foundations State of the Art
(Chapter, 2019)The huge growth and intense development in the European offshore wind power sector over the last decade have created significant achievements within the wind turbine foundation technology. The state of the art focusing on ... -
Acoustic characterization of an artificial CO2 seep using split-beam echo sounders
(Peer reviewed; Journal article, 2019)Geological carbon storage (GCS) has emerged as a promising method for reducing greenhouse gas emissions and achieving international climate goals. Currently, sub-seafloor GCS sites sequester about 1.8 MtCO2/yr. Additional ... -
Geomechanical and Seismic Behaviors of Draupne Shale: A Case Study from the Central North Sea
(Chapter, 2019)Organic-rich shales exhibit a variation in shear strength and anisotropic behavior of seismic wave propagation when the direction of the plane of weakness is varied with respect to the direction of the principal stresses. ... -
Comparison of Sealing Properties of Amundsen and Drake Formations for Potential CO2 Storage in North Sea
(Chapter, 2019)Seal evaluation for CO2 storage is different from that of a hydrocarbon trap since the oil or gas accumulation itself validates the cap-rock integrity. However, in case of subsurface CO2 storage a careful investigation is ... -
The effect of biochar, lime and ash on maize yield in a long-term field trial in a Ultisol in the humid tropics
(Peer reviewed; Journal article, 2020)A multi-season field trial was carried out to investigate the effect of the amendment of biochar, lime, ash and washed biochar on the growth of maize. A degraded, strongly acidic Ultisol (pHKCl 3.60), with a relatively ... -
Undersøkelser av kjemisk utlekking og biota på testfelt på sjøbunnen i Grenlandsfjordene 2018-2019
(NIVA-rapport, Research report, 2019)Denne rapporten beskriver overvåking av spredning og biotilgjengelighet av dioksiner (PCDD/F), heksaklorbenzen (HCB) og oktaklorstyren (OCS) i de ni årene fra etablering av testfelt for tynnsjikt-tildekking i Grenlandsfjordene ... -
Granular viscosity from plastic yield surfaces: The role of the deformation type in granular flows
(Peer reviewed; Journal article, 2020)Numerical simulations of granular flows with Navier–Stokes type models emerged in the last decade, challenging the well established depth-averaged models. The structure of these equations allows for extension to general ... -
Bioaccumulation of Fluorotelomer Sulfonates and Perfluoroalkyl Acids in Marine Organisms Living in Aqueous Film-Forming Foam Impacted Waters
(Peer reviewed; Journal article, 2019)The use of aqueous film-forming foams (AFFFs) has resulted in hot spots polluted with poly- and perfluorinated alkyl substances (PFASs). The phase out of long-chained perfluoroalkyl acids (PFAAs) from AFFFs resulted in the ... -

Verification of a framework for cyclic p-y curves in clay by hindcast of Sabine River, SOLCYP and centrifuge laterally loaded pile tests
(Peer reviewed; Journal article, 2020)Pile foundations supporting offshore structures, such as jacket platforms, are subjected to cyclic lateral loading. The capacity and deformation of these pile foundations under cyclic lateral loading are important and ... -
Organic Content and Maturation Effects on Elastic Properties of Source Rock Shales in the Central North Sea
(Peer reviewed; Journal article, 2019)We investigate the effects of organic content and maturation on the elastic properties of source rock shales, mainly through integration of a well log database from the Central North Sea and associated geochemical data. ... -
Effect of conservation farming and biochar addition on soil organic carbon quality, nitrogen mineralization, and crop productivity in a light textured Acrisol in the sub-humid tropics
(Peer reviewed; Journal article, 2020)Conservation farming (CF), involving basin tillage, residue retention and crop rotation, combined with biochar may help to mitigate negative impacts of conventional agriculture. In this study, the effects of CF on the ... -
Los suelos marinos de la Sonda de Campeche y Litoral Tabasco, Golfo de México
(Chapter, 2019)En la Sonda de Campeche y Litoral Tabasco, Golfo de México, se han realizado más de mil sondeos geotécnicos y dos mil estudios geofísicos. Los sondeos tienen diversos objetivos, tales como: diseño de cimentaciones para ... -
The presence, emission and partitioning behavior of polychlorinated biphenyls in waste, leachate and aerosols from Norwegian waste-handling facilities
(Peer reviewed; Journal article, 2020)Even though production and open use of polychlorinated biphenyls (PCBs) have been phased out in Western industrialised countries since the 1980s, PCBs were still present in waste collected from different waste handling ... -
Nature-based solutions for hydro-meteorological risk reduction: a state-of-the-art review of the research area
(Journal article; Peer reviewed, 2020)Hydro-meteorological risks due to natural hazards such as severe floods, storm surges, landslides and droughts are causing impacts on different sectors of society. Such risks are expected to become worse given projected ... -
Inferences on Mixed Snow Avalanches from Field Observations
(Peer reviewed; Journal article, 2019)Observations of the deposits, flow marks, and damages of three mixed-snow avalanches of widely different size were analyzed with regard to flow regimes, velocities, pressures, densities, flow depths, erosion modes, and ... -
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, ...
