Preliminaly report of the TH96 geological and geophysical survey results in Bransfield Strait and its vicinity

Geophysical and geological surveys of the JNOC TH96 cruise on the R/V HAKUREI-MARU, in the Pacific margin of the northern Antarctic Peninsula, were carried out in the 1996-97 austral summer season. The early and later halves of the cruise were devoted to a continental margin survey of the western an...

The thickness of the sedimentary sequence in the abyssal plain is about 3 s (twt). The development of the continental rise between abyssal plain and continental slope is very poor, compared with more mature passive continental margins.

The deformation trend is interpreted to be controlled by the regional trend of simstral trans-tensional movement between the Antarctic and Scotia plates.
