The article is devoted to the development of an autonomous profiling system for measuring the aquatic environment under ice. The system moves up and down in the water column along a cable with a load at the lower end, which is lowered into a lane in the ice. The system carrier is designed for transporting an acoustic Doppler current profiler and a salinity, temperature, and pressure probe. The system will be useful for long-term measurements of vertical profiles of the current speed and marine environment parameters, as well as ice draft. The article describes in detail the structure and operation of the system. The hydraulic scheme of the carrier buoyancy system is presented.

The metallogenic efficiency of the marginal sea lithosphere of Northeastern Asia is associated mainly with the ore formation
variety of the remaining cratons and microcratons that defined the structural peculiarity of the region; these are setoffs
of the Precambrian basement, brachyform, anticline highs, and genesis of rifts within TMA periods. These formations allowed
us to explain the reasons for the unique metal-bearing feature of the marginal sea lithosphere of the Pacific Ocean ore belt
in addition to phenomena of an inherited nature of mineralization and conditions of formation of polychronous ore deposits. 相似文献

In this study we present the results of data processing from the 2004 Gelendzhik Bay expedition on the Akvanavt research vessel. The data were processed using the method of wavelet analysis. We found an emerging kilometer-scale variation
in the surface heaving and near-water wave over the shelf area. This effect was shown to be possibly caused by the inhomogeneity
of current in the depth-drop area. 相似文献
