... reconstructions in the south and north of West Siberia is probably caused by the recent permafrost. The authors inverted thermograms for the first two underwater boreholes drilled in the bottom of Lake Baikal near the Bugul’deika isthmus and on the Akademicheskii Ridge. These thermograms gave the same picture...

...Fig. 3. Lithology and photographs of cores sampled on Akademicheskii Ridge (core 96-64) and in the South basin of Lake Baikal (cores 97-7 and 97-8). Lithology of deposits (left column): 1 , Fe-Mn concretions; other labels follow Fig. 2 . Right column: 2 , oxidized sediment; 3 , reduced...

... Atlantic, Darhad Basin in Northern Mongolia, and bottom sediments of the Akademicheskii Ridge in Lake Baikal (BDP-98) ( Pechersky and Sharonova, 2013 ; Pechersky et al., 2008 , 2011 , 2013a , b , c ). To determine the rate of sedimentation in each section, we plotted a dependence of the thickness...

..., and the character of faulting mainly in two areas: the region of the Selenga delta and the region of the Akademicheskii Ridge [ 22 – 26 ]. The high resolution of the 1992 data as well as the highly precise navigation allowed us to determine reliably BSR on separate profiles and to map the gas hydrate layer...
