Origin and history of development of the Bransfield Straight (based on DSS data interpretation)
Essential difference in the structure of the earth’s crust of the northwestern continental margins of the Trinity peninsula (suboceanic) and Graham Coast (subcontinental) has been shown on the base of DSS data analysis. In agreement with similarity of geomorphologic elements on both sides of Bransfi...

In agreement with similarity of geomorphologic elements on both sides of Bransfield Trough it has been shown that the Antarctic Peninsula and South-Shetland islands could be a single structure that was a reason to come to conclusion on the probable origin of the straight as a result of spreading motion apart of the bottom as a result of riftogenesis.
