Highlights of the Svea expedition
All our guests participating in the 9th Svea Expedition left Svalbard for home and safely reached their destination just before the Covid-19 closing of borders. Now we summarise the experience:
– The weather was extremely tough, even harder than in 2019. We had – 25/10, that means at least -25⁰C temperature and 10 m/s wind. An ice thickness of 90 cm was just on the limit for our beautiful ice cutting machine Ditch Witch.
– Two new rubber tents (which we tested for the first time) were very useful and made experiments “doable”.
– We had a nice visit of a seal, who was very curious about our equipment, “helped” maintain water surface and gave us a lot of fun.
These tests were performed:
–Full-scale tests with fixed-ends beams;
–Full-scale tests on compression strength with short cantilever beams;
–Full-scale indentation tests;
–Full-scale indentation tests and small scale; compression tests on the ice subjected to vibrations;
–Tow floe experiment;
–Investigation of ice action on the Arctic quay.
Tree AOCEC students for spring 2020
This spring semester three students were supported by the AOCEC project. They are PhD student Trygve Løken (UiO, Norway), MSc student Thea Ellevold (UiO, Norway), and MSc student Aleksandra Visich from MIPT (Russia).
The students participated in the Svea expedition and performed their project work.
Svea Expedition – Ice action on an Arctic quay
We investigated ice processes on offshore side of cofferdam of the coal quay in Kapp Amsterdam, Svea. Timelaps camera Reconix, thermistor-string Geoprecision and ice pressure cells Geokon were installed on the research site. We were lucky to have fieldwork in the time of extreme tidal variation. Difference between low and high tide was 2.1 m and we observed water floods on the ice surface in high tide. See time-lapse video here.
We investigated temporal evolution of thermo-mechanical stresses in the ice near the cofferdam. Nataly Marchenko performed Laser scanning and 3D modelling in RiScan and Agisoft program. See 3D model of cofferdam deformation here.
Svea Expedition – Mechanical tests
The following tests were performed:
Full-scale tests with fixed-end beams, short cantilever beams and indentation tests were performed in parallel with small scale tests on uniaxial compression of ice cores to investigate scale effects of sea ice compression strength. Indentation tests and tests with ice cores were performed on natural sea ice and on sea ice preliminary subjected to the action of vibrating plate. Sea ice structure was investigated by in-situ analysis of thin sections.
Svea Expedition – Tow floe experiment
The floe was towed forward and back cyclically along the pool 4×6 m by 2 winches. The water velocities below the ice were recorded below the ice with ADCP and ADV to investigate the generation of under-ice turbulence by the floe motion. Water temperature was recorded with SBE-39 plus mounted together with ADV to investigate the influence of the flow motion on the ocean heat flux. Accelerometers and load cell were used to record the characteristics of flow motion. ROV, underwater camera and bubbling were used to visualize the water motion.
Prof. David Cole
Dartmouth college Prof. David Cole had his third visit to UNIS (the first was in autumn 2016, the second in spring 2018).
Dr. David Cole is a widely recognized scientist in the field of ice mechanics and microstructures of ice, artist of thin section analysis performing.
During the visit he held a lecture series for the students on the AT-211 course, participated in fieldwork in Svea, making experiments and supervising the students.
Establishing Svea Expedition Camp
After testing the ice thickness in the fjord (more than 90 cm) and facilities (warm hangar), Kapp Amsterdam was chosen as a working place. Extremely cold weather, thick ice and the demolishing of Svea Mine created a lot of challenges for fieldwork this year.
We started with unloading and distribution of equipment, building of tents and cutting ice for test.
9th “Svea expedition” departure
After a safety briefing the team is ready to drive snowmobiles 70 km to the former miner settlement Svea and perform investigation of fast ice properties for 2 weeks. Among the participants this year are: 2 from University of Oslo, 3 from Lomonosov Moscow State University, 1 from SMTU, 1 from Krylov State Research Centre, St. Petersburg, 1 from MIPT (Russia), 1 from GOIN (Russia), 1 from Dartmouth College (US), 1 from Prokhorov General Physics Institute, Moscow (Russia)
With strong UNIS leadership and logistical support, the team will expand on the work started in 2013 and continued in the last years: testing of the new rig, in-situ identational tests, beam test, compression-strength test; tide measurements. Investigation of hinge zone and waves under the ice (since 2019) will be also performed. Several inventions (big tent, milling machine, etc.) will be tested.
Experiment in Cold lab
According to «established AOCEC teamwork procedure”, lab work and dealing with small scale testing proceded field work in Svea.
New this year is the experiment on the registration of electro-magnetic radiation caused by the ice failure events. Experiment on thermal expansion of sea ice and lake ice, investigation of creep of the system holding fiber optic sensors were continued. The following tests were performed:
-Tests for the investigation of ice rheology in a wide spectral range
-Tests with vibrating cantilever beams
-Tests with vibrating fixed-ends beams (new rig for the lab tests was designed and constructed)
-Loading-unloading tests with ice cores
-Measurement of sound speed in ice samples
Amy Price – AOCEC MSc student in autumn 2019
Amy is a master student from the Memorial University of Newfoundland (St.John’s, Canada), division of Ocean and Naval Architectural Engineering. Prof. Brian Veitch is her supervisor.
She came to participate in field and lab work and obtain experience. Amy was very inspired by Longyearbyen and full-scale experiments. Together with Andrii and Igor, Amy presented North American part of AOCEC this Autumn at UNIS.
Igor Gribanov – AOCEC PhD student in autumn 2019
Igor is a PhD student from the Memorial University of Newfoundland (St.John’s, Canada), division of Ocean and Naval Architectural Engineering. Prof. Rocky Taylor and Robert Sarracino are his supervisors.
Igor spent many hours to model the L-shape beam, and wrote the article on it for the POAC conference. Now he had a chance to see the beam in reality and work in the field and lab. Igor was very impressed by the AOCEC hardworking team and our enthusiasm to hear his presentation on a Saturday evening. He reflected on his impression on Facebook.
UNIS – Andrii is back to AT for tests
During AOCEC meeting in St.John’s, participants discuss the possibility to run the experiment on 3 points cycling loading of ice beams.
Andrii Murdza (DC) came to perform this experiment in UNIS cold lab. He was happy to visit UNIS for the 5th time (read about his former involvement here) and work in the lab and the field.
Longyearbyen – Laser scanning
Dr Nataly Marchenko and PhD Student Fedor Yurov (MSU) performed the 3rd laser scanning on Svalbard Airport Runway and the roads in Longyearbyen. Now we can see and measure the changes, happening during the past 2 years and talk about the reasons and draw conclusions. The deformations influence operational safety and significantly increase the cost of maintenance. Laser scanning and mapping provide a new opportunity to quantify the visible deformations via 3D modelling, detect changes and determine the most sensitive places. This year we scanned Ground Control Points and also tested Trimble Catalyst Antenna –the advanced devise for fast and accurate (some cm) measurement coordinate.
UNIS – Field work reflection
Scientists and students spent a lot of time on discussing the results of the experiments, trying to find the best procedure, planning the future work and common publications.
UNIS cold lab – Ice testing
According to «established AOCEC team work procedure”, field work was combined with lab work, dealing with small scale tasting.
The next tests were performed:
Uniaxial compression strength of ice cores taken from sea ice and lake ice;
3 points bending tests with beams made from sea ice and lake ice;
Tests on 3 points cycling loading of ice beams and tests on vibrations of cantilever beams. Loads, displacements, accelerations and acoustic emission were recorded during the tests versus the time.

Guest lecturer from MUN at UNIS
Dr. Robert Sinclair Sarracino (Memorial University of Newfoundland, MUN) spent two weeks at UNIS, teaching on AT-332 and performing consulting on computer modeling with Comsol Multiphysics and LS-Dyna software.
During his stay here he got an unforgettable experience of fieldwork with the ice and approaching darkness.
Seminar after lab and fieldwork
Reflection on this year’s (spring and autumn) field and lab activities is an important part of the annual procedure. Late autumn is the time for abstract submission for the next year conferences and preparation of the papers.
The key topics are how to design the new test geometry to diminish the influence of stress concentrations on the experimental results, how to model the mechanical ice processes with known techniques and software, use the results of fieldwork and full-scale experiments.
Professors in the photo (all were teaching on the AT-332 course) are Robert Sarracino (MUN), Alexander Sakharov (MSU), Aleksey Marchenko (UNIS), Evgeny Karulin (SMTU), Dmitry Onishchenko (VNIIGAZ) and Petr Chistyakov (MSU).
Students from the AT-332 course perform fieldwork as the part of their studies. Previously they worked in groups performing tests on ice strength under compression, tension and bending and analyzing thin sections of ice in the lab. Now they work in-situ, doing tests with floating cantilever beams on flexural strength. The tests will be following by computer modeling in Comsol Multiphysics.
Work on the lake near Mine 7 is a valuable experience for students in the term of participation in unique full-scale experiments, and testing of resistance to cold conditions.
The challenge this year was very foggy weather.
The 6th Lake Expedition
Investigation of fresh ice on the lake located between Mine 7 and EISCAT on the elevation 400 m above sea level was performed at the first time in 2013 in the frame of the SMIDA project. Since that the so-called “Lake expedition” has become a regular expedition. In 2015–2017 it was supported by the SITRA project and now by AOCEC.
Each year, the team runs ice mechanical tests and show students of the AT-332/832 course the basis of full-scale experiments.
Ice conditions on the lake this year were good (thickness 40 cm, little snow) and the AOCEC team managed to perform several ice mechanical tests.
Regular participants of the “Lake expedition” are: Professors Alexander Sakharov and Petr Chistyakov (MSU), Aleksey Marchenko (UNIS), Evgeny Karulin (SMTU).
AT-332 course lab work
Students made experiments in the lab under the supervision of prof. Aleksey Marchenko, Dr. Jean Rabault (UiO) and prof. Vladimir Markov (MSU). Using a wave tank with generating waves paddle and wave absorbing grids and four sensors, they investigated the relation between frequency, group and phase velocity in water waves and made a comparison with the theoretical results. Using a setup consisting of a rod with a metal sphere, an accelerometer and several extra massive pieces, they found added masses of a pendulum in water.
These experiments are very important for the understanding of floe-floe interaction in wave conditions and modelling of wave damping in ice covered areas.

The first AOCEC Master project
Msc Student Fedor Yurov (MSU with supervising by Dr Nataly Marchenko) performed laser scanning on Svalbard Airport Runway and the roads in Longyearbyen. Transport infrastructure in the northernmost town suffers from large deformations due to permafrost degradation, which has increased during the past warm years. These deformations influence operational safety and significantly increase the cost of maintenance. Laser scanning and mapping provide a new opportunity to quantify the visible deformations via 3D modelling, detect changes and determine the most sensitive places.
Study cruise in the Barents Sea
Students from the AT-211 course and researchers from UNIS and P.P. Shirshov Institute of Oceanology (Russia) spent an unforgettable 5 days on board the Governor’s ship Polarsyssel. Sea ice observations, ice mechanical tests, oceanographic measurements, laser scanning on the most south sea ice limits were performed. Valuable data about ice-tongue stretching to Bjørnøya (Bear Island) was obtained.
