Maximum frontal speeds, alpha angles and deposit volumes of flowing snow avalanches
(Peer reviewed; Journal article, 2018)Approximate maximum frontal speeds from 89 snow avalanches were analyzed to yield probabilistic estimates of maximum speed scaled with path length parameters. In addition to speeds, 88 companion values of runout for the ... -
Metagenomics in CO2 Monitoring
(Journal article, 2013)Leakage from CO2 storage areas is likely to affect the microbial communities in the overlaying sediments. We have conducted a baseline characterization of the microbial communities present in the surface sediments overlaying ... -
Microplastic accumulation by tube-dwelling, suspension feeding polychaetes from the sediment surface: A case study from the Norwegian Continental Shelf
(Peer reviewed; Journal article, 2020)Sediment samples (0–1 cm) and tube-dwelling polychaetes from the Norwegian Continental Shelf and the Barents Sea were collected, including areas close to oil and gas installations and remote locations. Microplastics (≥45 μm) ... -
Microseismic monitoring and interpretation of injection data from the In Salah CO2 storage site (Krechba), Algeria
(Journal article, 2013)Microseismic data analysis together with interpretation of injection data at the In Salah CO2 storage site provides a valuable tool for improved understanding of the subsurface injection and storage processes. More than ... -
Mind the Gap: Towards a Typology of Climate Service Usability Gaps
(Peer reviewed; Journal article, 2020)Literature on climate services presents a large diversity of different services and uses. Many climate services have ‘usability gaps’: the information provided, or the way it is visualized, may be unsuitable for end users ... -
Modeling propagation and inundation of the 11 March 2011 Tohoku tsunami
(Journal article, 2012)On 11 March 2011 the Tohoku tsunami devastated the east coast of Japan, claiming thousands of casualties and destroying coastal settlements and infrastructure. In this paper tsunami generation, propagation, and inundation ... -
Modelling creep behaviour of anisotropic soft soils
(Journal article, 2015)This paper presents a three dimensional constitutive model that describes the creep behaviour of natural clays with anisotropic stress–strain response, focussing on robust model implementation. Creep is formulated using ... -
Modelling of soil-structure-interaction for flexible caissons for offshore wind turbines
(Peer reviewed; Journal article, 2018)Published foundation models and procedures for calculation of caisson foundation response typically assume a rigid caisson in deformable soil. However, recent published measurement data from a prototype suction bucket ... -
Modelling the 1929 Grand Banks slump and landslide tsunami
(Chapter, 2018)On 18 November 1929, an Mw 7.2 earthquake occurred south of Newfoundland, displacing >100 km3 of sediment volume that evolved into a turbidity current. The resulting tsunami was recorded across the Atlantic and caused ... -
Monitoring alkylphenols in water using the polar organic chemical integrative sampler (POCIS): Determining sampling rates via the extraction of PES membranes and Oasis beads
(Peer reviewed; Journal article, 2017)Polar organic chemical integrative samplers (POCIS) have previously been used to monitor alkylphenol (AP) contamination in water and produced water. However, only the sorbent receiving phase of the POCIS (Oasis beads) is ... -
Monitoring strategies for local landslide early warning systems
(Journal article; Peer reviewed, 2018)The main aim of this study is the description and the analysis of the monitoring strategies implemented within local landslide early warning systems (Lo-LEWS) operational all around the world. Relevant information on 29 ... -
Monotonic and dilatory excess pore water dissipations in silt following CPTU at variable penetration rate
(Chapter, 2016)The relationship between cone penetration rate and pore pressure decay is investigated through dissipation tests following penetration at different rates. Field tests and model scale tests in the laboratory are performed. ... -
Multi-year double cropping biochar field trials in Nepal: Finding the optimal biochar dose through agronomic trials and cost-benefit analysis
(Peer reviewed; Journal article, 2018)Poor water and nutrient retention are the major soil fertility limitations in the low productivity agricultural soils of Nepal. The addition of biochar to these soils is one way these hindrances can be overcome. In the ... -
National database for mitigative measures against rapid gravity mass flows and rock falls
(Lecture, 2012)Mitigation measures against natural catastrophes, such as rapid gravity mass flows and rock falls, have been built in Norway for centuries. Over the last few decades the number of new constructions has been increasing due ... -
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 ... -
NE Atlantic continental slope stability from a numerical modeling perspective
(Peer reviewed; Journal article, 2018)Trough mouth fans are environments characterized by high sediment supply during glacial stages and the occurrence of large-scale instabilities. The geological record indicates that several of these environments have failed ... -
Nonlinear soil-pile interaction for offshore wind turbines
(Journal article; Peer reviewed, 2018)The current work presents a parametric study, which involves different generalized nonlinear mechanical formulations with different damping characteristics to account for the interaction between a monopile‐supported offshore ... -

Not extinct yet: innovations in frequency domain HEM triggered by sea ice studies
(Journal article, 2015)The last 15 years have brought major innovations in helicopter towed time domain electromagnetics (EM), while few further developments have been made within the classic frequency domain segment. Operational use of frequency ...
