Анотація

Хоча рельєф дна і геофізичні параметри ложа котловини моря Скоша загалом вивчені досить добре і розглядалися в багатьох публікаціях, усе ж таки й досі залишаються питання щодо тектоніки центральної частини ложа цієї котловини. Тектонічна частина природи західної частини дна моря Скоша добре демонструється Західним рифтогенним хребтом, а у східній частині - Східним задуговим рифтом. Центральна частина ложа котловини зазвичай інтерпретується як упроваджений фрагмент Тихоокеанської плити або як заново створена океанічна плита, результат гаданого рифтогенезу. Найновіші дослідження рельєфу дна та інші геофізичні зйомки у сполученні зі збиранням геологічних зразків приводять до припущень про існування там великого релікту континентального моста поміж Південною Америкою і Західною Антарктидою - палео-Землі Скоша.
