Аннотация

Исследовались встречаемость и распределение финвалов и горбачей по маршруту следования НИС “Академик Мстислав Келдыш” в Атлантическом секторе Антарктики в январе–феврале 2022 г. Рассматривались особенности распределения китов в зависимости от глубины акватории, концентрации и половозрелости антарктического криля, содержания хлорофилла “а” в воде. Самая высокая встречаемость финвалов была обнаружена в глубоководных районах бассейна Пауэлла и Оркнейского желоба, где было зарегистрировано преобладание взрослого криля, а горбатых китов – в мелководном проливе Брансфилда, где преобладала молодь антарктического криля. Зависимость встречаемости китов от концентрации хлорофилла “а” не подтвердилась.

Ключевые слова: Атлантический сектор Антарктики, китообразные, финвалы, горбатые киты, встречаемость, пространственное распределение
