Studies of the strength parameters of the ice fields at the drifting stations

Sea ice is a very complex multiphase viscoelastic medium, its strength properties and characteristics are essential for the design of hydraulic structures and icebreaking vessels. The measurements of the corresponding parameters were performed by the simultaneous measurement of stresses in the ice, upward pressure on the lower surface of the fields and seismic measurements at several points. The methods used were both passive (measurements during the passage of storm disturbances coming from the ocean) and active (impact load – landing of an airplane on the icefield). The collected data for the ice fields of various ages, sizes and thicknesses were used in the corresponding mathematical model.

Elbrus

1994 Elbrus magnetometric and sports Expedition (co-director)

Testing methods for monitoring of magnetic fields on the slopes of Mount Elbrus

The method is based on the model proposed by S.Siparov. According to this model, the effective magnetic moment of the volcano changes with increasing temperature in the bulk, due to increased activity of the magma chamber. The magnetic characteristics are measured at the surface using a magnetometer, developed by B.Kuznetsov. Their change in a predicted manner serves as a control signal. The method is a means of monitoring volcanic activity and eruption forecasting.   Sergey Siparov. Testing methods for monitoring of magnetic fields on the slopes of Mount Elbrus
