Геоморфология хребта Девяностого градуса

P. A. Lemenkova

Аннотация


В данной статье исследуются пространственные вариации геоморфологии хребта Девяностого градуса, также известного как Восточно-Индийский хребет (ВИХ) в Индийском океане в трех сегментах. ВИХ представляет собой необычайно протяженный линейный батиметрический объект с топографией, отражающей сложные геофизические условия и геологическую эволюцию. Исследование основано на компиляции наборов батиметрических, геологических и гравиметрических данных высокого разрешения. Подводная геоморфология была смоделирована с помощью оцифрованных профилей поперечного сечения. Были выбраны три сегмента по геоморфологическим особенностям ВИХ: 1) северный; 2) центральный; 3) южный. Измеренные глубины были визуализированы в виде графиков, проведен сравнительный анализ статистических гистограмм распределения и повторяемости глубин. Работа вносит вклад в региональные исследования геоморфологии дна Индийского океана.
