THEORETICAL AND EXPERIMENTAL RESEARCH IN PHYSICS AND MECHANICS OF FROZEN GROUND.
GEOPHYSICAL METHODS OF PERMAFROST RESEARCH
Phenomenon might be explained through energy diagrams of the orientation and ion defects in ice and
water. Potential energy of defects (as well as formation energy of a pair of defects with opposite charges) is higher
in ice than in water. In accordance with that, equilibrium concentration of similar defects is greater in water. During
crystallization, defects are captured by ice in non-equilibrium amount. Their energy increases due to phase transition
heat. During structured transformations of ice, non-equilibrium defects recombine intensively, which is
accompanied by liberation of energy equal to the energy of pair formation. This energy can be spent on excitation of
chemically active particles and, thereby, reduction of activation barrier of chemical reactions. Consequently, the
intensity of chemical process will increase. Thereby, reaction acceleration in ice compared to that in water at the
same temperature is related to greater energy, liberated at during recombinations of defects and, as consequence, to
smaller resulting height of potential barrier of reactions.
MONITORING OF STRESS-STRAIN CONDITIONS OF COASTAL SLOPE ON "BOLVANSKY"
STATION BY USE OF SEISMORECONNAISSANCE

In 2002-2003 on the northern slope of cape Bolvansky (the estuary of Pechora river) seismic research have
been carried out to study the stress-strain conditions of the coastal ledge. Space-time forecasting of coastal slope
stability was the purpose of this research.
The methodical approaches used in this study were developed .earlier for seismic monitoring of landslide
process outside of the cryolitozone. We developed the principles of multiwave multiazimuth seismoreconnaissance
(MMS) technique based on simultaneous use of longitudinal and shear waves. It provides essential trustworthiness
and reliability increase of the space-time forecast of coastal slope stability at the stage before any displacement.
In 2002, seismic research has been carried out on four cross-sections 50-60 meters long located 20-30
meters from each other. We found weakened zones predicted to have massif discontinuity. The most dangerous zone
were located 7-10 meters from the coastal ledge. Superficial crack revealed at landscape mapping served as an
indicator of the forthcoming displacement in this zone. The crack was found 10-15 m west of the cross-section field .
In 2003, the repeated cycle of the seismic research was carried out using the same technique. The area of
the seismic research was expanded because of two new additional seismic cross-sections.
Two cycles of the seismic research, execut5d with one-year interval, have provided an opportunity of
monitoring landslide process. Comparison of the data showed that general regularity of the seismic characteristics
distribution was preserved, the reduction tendency of the coastal slope stability was observed.
Area regularity of seismic characteristics variability was most demonstrably shown on the differential maps
designed one the results of two seismic research cycles. Thus, the maximal changes of seismic characteristics
occurred within the weakened zones revealed in the first re.search year.
The results confirm that suggested multiwave mult?azimuth seismoreconnaissance technique has been the
effective tool of sp,~ce-time forecast of coastal ledge stability in t~e Arctic zone at the stage before any discontinuity
started.
This research is supported by INTAS M2332.
TRANSFORMATION OF OIL POLLUTION AREAS UNDER THE INFLUENCE OF CRYOGENIC
FACTORS

One of the actµal ecological problems in West Siberia is a high level of oil po~lution in the resource-saving
territories. The mathematical model of evolution of_ the sta~~ of oil-polluted are.as is presented in the report. This
model allows to estimate residual cor..tent of the poilutant in the areas of accidental oil spi!Is and to forecast its
assimilation in the conti~uous surroundings. The contaminated-!ield is characterized by the distributed content of
masses of contaminant (pollutant) in four cumulative media -mass. of surface contamination [MVi MS 1], mass of
ground contamination within the spill area and conforming masses of contaminant related to buffer zone. It is
surface stratum [MV2 MS 2 ] and soil contamination [MG 2 MGS 2 ]. For composition of combined equations of balance
of masses, the quantity of pollutant in these mediums is represented by two variables MV and MG, the quantity of
pollutant of fluid phase, capable to participate in the migration processes and the pollutants transformed in resinous
and solid phase - MS and MGS (bituminisation) unable !0 actively migrate. The dynamics of the mass's condition of
surface stratum (layer) complies with the combined equations:
dMV/dt= -A(nzP1+mD1+mG1+.mR1)- mS1 -mEVi + mU1 -mrU1,

dMS/dt = mS1 - mES1 - m.rS1, ·
