Longyearbyen, Svalbard - Vulnerability and risk management of an arctic settlement under changing climate - a challenge to authorities and experts
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2016)Longyearbyen, the administrative centre of the Svalbard archipelago, is facing most types of natural hazards under a changing Arctic climate. The catastrophic avalanche in December 2015 led NGI to review our professional ... -
Looking Beyond the Powder/Dense FlowAvalanche Dichotomy
(Journal article, 2018-03-04)Köhler et al. (2018, https://doi.org/10.1002/2017JF004375) deploy a high spatial and temporal resolution GEODAR radar system to reveal the inside of snow avalanches over the entire slope. They detect a rich variety of ... -
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 ... -
Main aspects of deformation and rock support in Norwegian road tunnels
(Journal article; Peer reviewed, 2019)The general geology of Norway makes most of its tunnels to be constructed mainly in strong rock intersected by weakness zones of different sizes and characteristics. The Norwegian support tradition is, to the largest degree ... -
Mapping tsunami impacts on land cover and related ecosystem service supply in Phang Nga, Thailand
(Journal article, 2013)The 2004 Indian Ocean tsunami caused damages to coastal ecosystems and thus affected the livelihoods of the coastal communities who depend on services provided by these ecosystems. The paper presents a case study on ... -

Mathematical modeling of dense avalanches
(NGI Publication;203, Chapter, 1998)The paper presents a brief overview of mathematical models for dense avalanches that were developed by researchers of Moscow State University. Examples of calculations for real avalanches in Caucasus and Khibiny Mountains ... -
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 ... -
Måleresultater etter fullskala sprengningsforsøk – hvor kraftige vibrasjoner tåler en bygning før det oppstår skader
(Conference object, 2019)Grenseverdier for sprengningsvibrasjoner fastsettes på grunnlag av NS 8141 Vibrasjoner og støt. Bergsprengning kan gi så kraftige vibrasjoner at det forårsaker skader på tilstøtende byggverk. Det er imidlertid sjelden at ... -
Measurement of avalanche speeds and forces: instrumentation and preliminary results of the Ryggfonn project.
(Journal article, 1985)The Ryggfonn project is a Full scale experiment carried out to investigate the impact of avalanches on structures and the effects of a retaining dam in the avalanche path. The vertical drop of the avalanche path is 910 m ... -
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 ... -
The meteorological condition for larger avalanches at Senjojiki Bowl in Japanese Central Alps
(NGI Publication;203, Chapter, 1998)The Senjojiki Bowl has a typical avalanche terrain consisting of8 avalanche tracks. During the last 25 years 16 alpinists and ropeway workers in total have been killed by avalanches. Since no reliable avalanche warning is ... -
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 ... -

A model for frictional melt production beneath large rock avalanches
(Journal article, 2008)Two puzzling traits of giant rock avalanches (sturzstroms) are the decrease of the effective friction coefficient as a function of the volume (volume effect) and the remarkable preservation of large geological structures ...
