Dr. Sinitsyn’s research group pursued three primary
goals in their work:
• to continue topographical measurements of erosion
rates in this area based on survey profiles established
and maintained since 1980;
• to make existing systems of profiles denser and to
establish one profile with boreholes for temperature
measurements and soil analysis, and to designate an
area in proximity of one of the profiles (within 0.5 km)
to be topographically surveyed as well;
• to investigate local logistic possibilities and conditions
to determine accessibility for further field work.
“Field work during the research project covered the
entire 72 kilometer coastline in the Varandey area,
which gives researchers the ability to study erosion
processes systematically in full-scale within a large
nature subject. We included in our survey at Varandey
Island, Pesyakov Island and the Medynsky Zavorot
Peninsula,” said Dr. Sinitsyn.
The Baydaratskaya Bay field site was established by
SAMCoT scientific partner Moscow State University
(MSU) as joint activity with SINTEF. SAMCoT participated
in important discussions that determined the impor
tance of this specific field work and Prof. Brouchkov
recognizes that the exchange of experience provided by
SAMCoT’s researchers was particularly helpful.
The 20-day Varandey Expedition 2012 was organized
in cooperation with the State Oceanographic Institute
(SOI), UNIS and SINTEF. SOI provided scientific basis
for research, communication with official authorities,
transportation to the site, equipment, human resources
and HSE documentation.
UNIS provided scientific basis, HSE documentation,
equipment and human resources. SINTEF provided
equipment and consulting support for technical
solutions.
The extensive technology and methods used in the
Varandey Expedition include:
• Drilling work: drilling and penetration tests
• Soil sampling for physical analysis and radiocarbon
analysis (isotope 14C)
• Arrangement of wells for temperaturemeasurements
• Topographical measurements at polygon with drilling
works
• Topographical measurements for erosion rates
estimation
• Measurements of erosion rates with use of ruler
• Observations of geocryological structures on thermo-
abraded slopes
• Survey on distribution of the thickness of active layer
across Pesyakov Island
