A tsunami wave recorded near a glacier front
Marchenko, Aleksey; Morozov, E.G.; Muzylev, S.V. (Journal article; Peer reviewed, 2012)We observed a tsunami wave near the glacier front in the Temple Fjord (Spitsbergen). Two temperature and pressure recorders were deployed on a wire from the ice approximately 300 m from the glacier front. A pressure recorder ... -
An experimental comparison of thermal-mechanical properties of freshwater and saline ice in Arctic environments
McMaster, Elizabeth Jean (Master thesis, 2021)Termisk istrykk er en av de åtte islastene som må vurderes for støttestrukturdesign av bunnfestede havvindmøller definert av internasjonal standard IEC 61400031. Temperaturendringer i is driver dens deformasjon og forårsaker ... -
Asymmetric tide in Lake Vallunden (Spitsbergen)
Marchenko, Aleksey; Morozov, E.G. (Journal article; Peer reviewed, 2013)We observed strongly asymmetric tide in a channel connecting the Van Mijen Fjord and Lake Vallunden in Spitsbergen. The channel is approximately 100 m long, 10 m wide, and 1–2 m deep. Asymmetric tide was also observed in ... -
Experimental and numerical studies related to failure of first-year ice ridges against fixed vertically sided structures
Ervik, Åse (Doctoral theses at NTNU;2019:192, Doctoral thesis, 2019) -
Measurements of sea-ice flexural stiffness by pressure characteristics of flexural-gravity waves
Marchenko, Aleksey; Morozov, Eugene G.; Muzylev, S (Journal article; Peer reviewed, 2013)A method to estimate the flexural stiffness and effective elastic modulus of floating ice is described and analysed. The method is based on the analysis of water pressure records at two or three locations below the bottom ... -
Observations and Numerical Simulation of Icebergs in Broken Ice
Yulmetov, Renat (Doctoral theses at NTNU;2017:24, Doctoral thesis, 2017)Sea ice and icebergs are the major challenges for offshore activities in the Arctic. Design loads for Arctic offshore structures may be significantly reduced if the drift of sea ice and icebergs is possible to forecast ... -
Stress measurements in landfast sea ice in Van Mijenfjorden,Svalbard.: A survey of internal stress in landfast sea ice winter 2014.
Vindegg, Carl Magnus (Master thesis, 2014)During the winter 2014 a fieldwork was conducted in Van Mijenfjorden, Svalbard. The main objective of the fieldwork was to investigate stress development in confined landfast ice. Investigation were performed at two sites: ... -
Svalbard fjord environments with land-fast sea ice as arenas for climate research, monitoring, remote sensing validation, and dedicated process studies
Gerland, Sebastian; Divine, Dmitry V; Fransson, Agneta; Granskog, Mats; Pavlova, Olga; Chierici, Melissa; Høyland, Knut Vilhelm; Johansson, Malin; Marchenko, Aleksey (Peer reviewed; Journal article, 2020)During winter and spring, parts of Svalbard fjords are covered with land-fast sea ice. The extent of fast ice areas has decreased during the last two decades, and seasons with fjord ice cover have on average become shorter. ... -
The Role of the Thermodynamic Consolidation of Ice Ridge Keels in the Seabed Gouging Process
Shestov, Aleksey (Doctoral Theses at NTNU, 1503-8181; 2013:253, Doctoral thesis, 2013)Many engineering challenges are currently posed by the Arctic and the sea ice found there. Ice ridge keels have attracted significant attention because of the potential damage they can inflict on subsea installations. The ...
