Structure of the Nearsurface Sediments in the Scan Basin (Scotia Sea)
The structure of the precipitation of the Scotia Sea is important to the recovery of the geological history of the latest stage of development of its bottom in the Late Quaternary. One of the main elements of geomorphological bottom south of the Scotia Sea is a basin Scan. Formation Scan depression played a significant role in fragmenting the continental-tal array comprising banks Bruce and Discovery. It is established the basic parameters of the sedimentary sequence Scan depression, but the uppermost part of the section is not reflected in the literature due to lack of data. The first presentation of the data of the present work. Based on analysis of data from the r./v. "Gesperidas" in 2012 with the help of high-resolution seismoprofiler TOPAS PS18/40, for the first time in the cavity scan revealed three layers of surface sediments. The estimation of the average time deposits layers of latequaternary age: the first from the surface of the bottom - 115 thousand. years, the second - 76 thousand. years, a third - 59 thousand. years. At the same time, the total accumulation of sedimentary material all three layers is of 250 thousand. years.
