development of a 1D lattice model. The 1D model devel
opment confirmed that the chosen approach can lead
to a model capable of predicting intermittent crushing,
frequency lock-in and continuous brittle crushing. This
model is now being further developed into a 2D model.
The research has also pursued an analogy with other
fields of dynamic flow-structure interaction as well as
the velocity-effect of ice-induced vibrations.
Coastal Technology
Coastal erosion is a severe and complex condition
observed in many places in the Arctic. To understand the
processes behind this erosion, SAMCoT participated in
field studies of seven coastal permafrost sites, including
Spitsbergen and northwest Russia. These registrations
are mainly based on yearly DGPS measurements and
aerial photography. Soil properties have been investi
gated by installation of onshore data collectors, includ
ing piezometers and thermistor strings.
At one site, Vestpynten at Spitsbergen, studies of how
snowdrift in the coastal zone affects the temperature
regime in the coastal permafrost is studied and, the effect
this snowdrift may have on erosion rates. Observations
related to the presence of fjord ice clearly indicate
that extremely long periods of ice-free seas cause
substantially increased erosion rates. Geosynthetic
tubes and bags using local soil as filling material have
been developed and are now being tested for shoreline
protection.
In-situ testing and laboratory testing are also required
to understand the behaviour of permafrost from an
engineering perspective. Thus, equipment has been
developed for high quality soil sampling.
Associated Projects
Associated Projects are separate projects initiated by
one or several SAMCoT partners. These projects benefit
from existing know-how acquired through SAMCoT
activities and build on the involvement of SAMCoT staff.
Two Associated Projects were conducted in 2012:
• Oden Arctic Technology Research Cruise 2012
(OATRC2012), headed by NTNU in cooperation with
the Swedish Polar Research Secretariat (SPRS), The
University Centre in Svalbard (UNIS) and Statoil.
• EU HYDRALAB – IV Project “Rubble Ice Transport
on Arctic Structures” (RITAS), a project headed by
Multiconsult and supported by HSVA, Statoil and NTNU.
A Thank You to All Our Contributors
I would like to take this opportunity to thank everyone
who joined us in 2012 for their contributions to SAMCoT’s
progress and successes during the year. We should all
remember that a Centre for Research-based Innovation
(SFI) should include the industry partners and ensure
quality and relevance of the research being done. To
keep this vital interaction intact is demanding and it is
best achieved through the devotion demonstrated by
SAMCoT’s working committees, review processes and
workshops, as well as the co-supervision support the
PhD candidates receive from our partners.
The year 2012 was SAMCoT’s first full year and a number
of new PhD candidates began it with mandatory courses
before continuing with academic work. Already we now
see the first fruits of this seeding phase, manifested in a
number of publications being disseminated in 2013.
Once again, thanks to each of you. I look forward to
continuing another exciting year in 2013.
