Accoustic snow drift measurements: Experiences from the FlowCapt instrument
(Journal article, 2001)Three acoustic FlowCapt™ (IAV Engineering) drifting snow instruments were deployed during the 1999 and 2000 field season on Spitsbergen, Norway. Three different experiments were carried out to test the instruments for their ... -
Acoustic and petrophysical properties of mechanically compacted overconsolidated sands: part 1 – experimental results
(Journal article; Peer reviewed, 2019)This paper part one is set out to lay primary observations of experimental compaction measurements to form the basis for rock physics modelling in paper part two. P‐ and S‐wave velocities and corresponding petrophysical ... -
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 ... -
Acoustic sensor to measure snowdrift and wind velocity for avalanche forecasting
(NGI Publication;203, Chapter, 1998)A new mathematical model of slushflow dynamics is developed. A slushflow is treated as a two-layer flow. The lower layer consists of pure liquid phase (water) and the upper layer is a floating water saturated snow (slush). ... -
ACT4storage - Acoustic and Chemical Technologies for environmental GCS monitoring. D4 - Recommended guidelines report
(NGI-rapport;20180127-04-R Rev. 1, Report, 2020-11-10)Carbon capture and storage (CCS) is a promising tool for accelerating decarbonization and reaching international climate goals. The process involves capturing CO2 from energy-intensive industries such as waste-to-energy ... -
ACT4storage - Acoustic and Chemical Technologies for environmental monitoring of geological carbon storage. D3 - Nearshore evaluation report 2019
(NGI-rapport;20180127-03-R Rev. 2, Report, 2021-02-01)This report is the second delivery of the CLIMIT demonstration project ACT4storage (Acoustic and Chemical Technologies for environmental monitoring of geological carbon storage). The ACT4storage project is funded by ... -
Activities of the Japanese-Norwegian collaboration of snow avalanche research during the winters 1990/1991 and 1991/1992. Final report
(NGI-rapport;58120-29, Research report, 1993-03-05)The report gives a brief summary of the activities carried out by the Japanese - Norwegian collaboration on snow avalanche reasearch during the winters of 1990/1991 and 1991/1992. The research was mainly carried out in the ... -
Activities of the Japanese-Norwegian collaboration on snow avalanche research, march 1991
(NGI-rapport;58120-23, Research report, 1991-08-01)The report gives a brief summary of the activities carried out by the Japanese - Norwegian collaboration on snow avalanche reasearch during the winter of 1990/19991. The research was mainly carried out in the Ryggfonn ... -
Adaptation for practitioners
(NGI-rapport;20150014-13-R, Research report, 2018-12-18)An important attribute of the recently developed REDWIN foundation models – developed to be used for integrated analyses of offshore wind turbines (OWTs) – is that they are flexible in how their input can be obtained. ... -
Advancing the Use of Passive Sampling in Risk Assessment and Management of Sediments Contaminated with Hydrophobic Organic Chemicals: Results of an International Ex Situ Passive Sampling Interlaboratory Comparison Michiel T. O. Jonker*† , Stephan A. van der He
(Peer reviewed; Journal article, 2018)This work presents the results of an international interlaboratory comparison on ex situ passive sampling in sediments. The main objectives were to map the state of the science in passively sampling sediments, identify ... -
Advantages and limitation of using 2-D FE modelling for assessment of effect of mitigation measures for railway vibrations
(Peer reviewed; Journal article, 2019)This paper addresses mitigation measures against railway vibrations in soft soils by use of FE calculations. In order for calculation models to be used as design tools, it is essential that they are relatively easy to set ... -

Algorithms for intelligent prediction of landslide displacements
(Peer reviewed; Journal article, 2020)Landslides represent major threats to life and property in many areas of the world, such as the landslides in the Three Gorges Dam area in mainland China. To better prepare for landslides in this area, we explored how ... -
All-weather avalanche activity monitoring from space?
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2014)Information on avalanche activity or on non-activity on local and regional scale is of great value for avalanche warning services, traffic authorities and experts responsible for safety in communities or ski resorts. In ... -
An analytical plane-strain solution for surface uplift due to pressurized reservoirs
(Peer reviewed; Journal article, 2018)In this paper, we present an analytical plane strain solution for surface uplift above pressurized reservoirs. The solution is based on a Fourier representation of the reservoir pressure. The plane strain model is developed ... -
