A Numerical Simulation of Permafrost Thermal Regime under a Heat Pump Chilled Foundation in Longyearbyen, Svalbard
Heller, Sarah Theresa (Master thesis, 2021)Climate change in the Arctic causes a critical warming of the permanently frozen subsoil. The livelihood of over 3 million people is affected by the projected degradation of permafrost until 2050. The sustainable development ... -
An analysis of international, national and local literature and the formulation of criteria, for the development of holistic sustainable Arctic coastal infrastructure.
Sherwin, Peter A. (Master thesis, 2020)Hurtige endringer i det arktiske sosialøkologiske system påvirker eksisterende bygd infrastruktur i en negativ grad, i tillegg til å øke interessen for dens videre utvikling. Grunnet ekspanderende næringer, samt Arktis’ ... -
Borehole thermal energy storage as a seasonal capacitor in the off-grid Arctic energy supply system
Kurttila, Marko Piitu Eemeli (Master thesis, 2021)This master thesis investigated the feasibility of borehole thermal energy storage and solar heating in the high arctic using Longyearbyen in Svalbard as a reference study place. Field work was conducted in Longyearbyen, ... -
Coastal Erosion Modelling in Hiorthhamn, Longyearbyen (Svalbard)
Antonello, Carlo (Master thesis, 2022)Kyst erosjon i Arktis er et pågående fenomen som representerer et relevant ingeniøremne for dets sosiale og miljømessige implikasjoner. Det er resultatet av flere prosesser som er veldig avhengige av de lokale innstillingene ... -
Comparison of Geoacoustic Models for Unfrozen Water Content Estimation
Lyu, Chuangxin; Ghoreishian Amiri, Seyed Ali; Grimstad, Gustav; Høyland, Knut Vilhelm; Ingeman-Nielsen, Thomas (Peer reviewed; Journal article, 2020)This paper reviews eight geoacoustic models applied to frozen soils: crystal growth models (grain cementing, grain coating, matrix supporting, and pore filling), the weighted equation (WE) model, Zimmerman and King's model ... -
Experimental study on creep of frozen marine fine-grained soil in Longyearbyen, Svalbard
Huang, Hao-Chen (Master thesis, 2020)In recent years, new challenges have arisen due to problems related to warming ground temperatures associated with permafrost degradation. The frozen soil creep is one of the main sources of the degradation. Creep has given ... -
Joint Acoustic and Electrical Measurements for Unfrozen Water Saturation Estimate—A Review
Lyu, Chuangxin; Ghoreishian Amiri, Seyed Ali; Gao, Hao; Ingeman-Nielsen, Thomas; Grimstad, Gustav (Chapter, 2019)The previous laboratory study of joint electrical resistivity and acoustic velocity measurements is reviewed for both consolidated and unconsolidated permafrost in this paper. The relation of logarithm of resistivity log(R) ... -
Measurements and Modelling of Arctic Coastal Environments
Monteban, Dennis (Doctoral theses at NTNU;2020:213, Doctoral thesis, 2020)The most pronounced effects of climate change are observed in the polar regions, especially in the Arctic, which is currently warming more rapidly than the rest of the world. The Arctic is losing sea ice, and the oceans ... -
Numerical modeling to estimate the impact of built infrastructure on permafrost degradation - Case study from Ilulissat, Greenland
Näke, Luisa (Master thesis, 2023)Infrastruktur i permafrostlandskap påvirker bakkens termiske regime og kan øke permafrostens nedbrytning. Stabiliteten og brukbarheten til infrastrukturen avhenger likeledes av de termiske forholdene i undergrunnen. ... -
Settlements at several masts of the power line constructed on sedimentary permafrost deposits in Sisimiut, West-Greenland: Field- and lab work, data processing and thermal modelling
De Ville, Tom (Master thesis, 2023)The electricity of Greenland’s second largest town, Sisimiut (West -Greenland), is supplied by a hydropower plant, located some 20 km north from the town. In late 2021, Nukissiorfiit – the Greenland public utilities company ... -
Thermo-Hydro-Mechanical simulations of artificial ground freezing
Cicchetti, Lorenzo (Master thesis, 2018)Hundreds of thousands of people in Alaska, Canada, Russia, and Greenland live on permafrost, which covers nearly 24% of the northern hemisphere (National Snow and IceData Center, 2018). Living conditions can be challenged ... -
Thermo-Hydro-Mechanical simulations of Artificial Ground Freezing
Cicchetti, Lorenzo; Grimstad, Gustav; Ghoreishian Amiri, Seyed Ali; Ingeman-Nielsen, Thomas (Chapter, 2018) -
Towards Circumpolar Mapping of Arctic Settlements and Infrastructure Based on Sentinel-1 and Sentinel-2
Bartsch, Annett; Pointner, Georg; Ingeman-Nielsen, Thomas; Lu, Wenjun (Peer reviewed; Journal article, 2020)Infrastructure expands rapidly in the Arctic due to industrial development. At the same time, climate change impacts are pronounced in the Arctic. Ground temperatures are, for example, increasing as well as coastal erosion. ...
