Field studies and modelling of sea state, drift ice, ice actions and methods of icebergs management on the Arctic shelf, 2015–2017 (FIMA)
Part of NORRUS PROGRAMME RUSSIA and the High North/Arctic 2014. Funded by the Research Council of Norway (RCN)
Project number: 243930/H30 Project period: 2015–2017
Funding: 5000 kNOK
Host institution: The University Centre in Svalbard
Project leader: UNIS Professor Aleksey Marchenko

State Oceanographic Institute (SOI, Moscow, Russia)
- Investigation and quantifying of physical environment in the regions of offshore development and navigational activity on the Arctic shelf;
- contribution to estimates of physical environmental actions on offshore structures and a reduced risk level related to operating offshore in the High North;
- strengthening of long-term research cooperation with leading research institutions in Russia involved in the industrial development in the High North.
We work in close cooperation with the Centre for Sustainable Arctic Marine and Coastal Technology (SAMCoT) at NTNU, UNIS and SINTEF, Norway.
Joint seminar and lab tests of ice
The FIMA team took park in the IAHR International symposium on ice (Ann Arbor, Michigan – US).
Prof. Aleksey Marchenko made a key note lecture: “Thermo-mechanical properties of saline ice and loads on structure “. The FIMA team presented the results of investigations of sea ice drift in the Barents Sea and mechanical properties of ice, ice action modeling. The papers have been published in the Symposium Proceeding, see publication list.
Full-scale ice mechanical tests in the Barents Sea
The team of RV LANCE came back to Longyearbyen after 8 days of survey in the Barents Sea.
This year’s cruise was held in usually warm weather conditions and mostly free of ice sea. We managed to find thick enough ice floe only to the north-east of Edge Island, but investigation of sea ice were performed successfully on two stations with good results. Some of them will be presented on IAHR Ice symposium in June.
Investigation of ice rubble in the West Barents Sea
During survey on RV LANCE, the Arctic Technology Ice Group of UNIS discovered a huge ice rubble near the east-north point of Edge Island. It was the first such observation, because usually this region is surrounded by sea ice and basically unreachable.
We made laser scanning with RIEGL VZ 1000, CTD and ADV measurement and will investigate this interesting phenomena further.
Field study of sea ice mechanical properties in Svea
The FIMA team performs full-scale testing of the new rig, in-situ identation tests, beam test, compression-strength test; CTD, ADCP profiling, tide measurements on the lake Vallunden, connecting with Van Mijenfjorden on the west of Spitsbergen.
|Full scale investigation of fresh ice on the lake and experiments at UNIS cold lab and project discussion.
