Abstract

The first comprehensive study of the deep-sea ecosystems of the Emperor Chain seamounts (the northwestern Pacific Ocean) was conducted in July–August 2019 by A.V. Zhirmunsky National Scientific Center of Marine Biology, FEB RAS. The expedition, using a remote-operated underwater vehicle Comanche 18, was aimed at the study of distribution of typical underwater landscapes and key taxa of Octocorallia corals and Hexactinellida sponges in the vulnerable marine ecosystem of the seamounts. New data on the macrobenthos biodiversity and biogeographic characteristics of deep-sea corals and sponges, which are the dominant animals in the studied area, are presented. The survey has shown changes of the coral fauna in the latitudinal direction and obtained new data on the biogeographic boundary in the area of the Emperor Chain seamounts.

皇帝链海山脆弱的海洋生态系统结构的第一个数据:指示类群,景观和生物地理学

摘要

由埃博·日蒙斯基国家海洋生物学国家科学中心FEB RAS于2019年7月至2019年8月对Emperor Chain海山(西北太平洋)的深海生态系统进行了首次综合研究。使用远程水下航行器Comanche 18进行探险旨在研究海山脆弱的海洋生态系统中典型的水下景观和八爪珊瑚和六角形海绵的主要分类群的分布。提出了有关深海珊瑚和海绵的大型底栖生物多样性和生物地理特征的新数据,深海珊瑚和海绵是研究区域的主要动物。调查显示了珊瑚动物群在纬度方向上的变化,并获得了有关帝王链海山地区生物地理边界的新数据。
