Abstract

According to the Plan of Complex Scientific Research of the World Ocean for 2017–2022, the V.I. Il’ichev Pacific Oceanological Institute, Far Eastern Branch, Russian Academy of Sciences, continues to study the northern part of the Sea of Japan and the Tatar Strait, carrying out a three-year plan of expeditionary research of this region. The expedition aboard the R/V Akademik Oparin (cruise no. 55) spanned from October 2 to 19, 2018. Geophysical and gas-geological study of the water area in the central and southern parts of the Tatar Strait was continued. On the rookery of Tyuleny Island, in the Sea of Okhotsk, information on sea lions and larghas were recorded, three individuals of northern fur seal were tagged with satellite trackers to study their migration routes. CTD observations of the upper layer (down to 600 m) were made on transects across mesoscale eddies in the northern part of the Sea of Japan. Expeditionary research was supported by the Council of the Earth’s Hydorsphere of the Ministry of Science and Higher Education of the Russian Federation.

R / V Akademik Oparin邮轮55号在日本海和鄂霍次克海进行的综合远征研究

摘要

根据《 2017-2022年世界海洋复杂科学研究计划》，俄罗斯科学院VI Il'ichev太平洋海洋研究所俄罗斯远东分校将继续研究日本海北部和塔塔尔海峡，执行了该地区的三年远征研究计划。R / V Akademik Oparin上的探险队（第55号巡游）时间跨度为2018年10月2日至19日。塔塔尔海峡中部和南部水域的地球物理和天然气地质研究仍在继续。在鄂霍次克海Tyuleny岛的群居中，记录了有关海狮和拉格海斯的信息，并用卫星跟踪器对三只北海豹个体进行了标记，以研究其迁徙路线。在日本海北部中尺度涡旋的横断面上进行了上层（低至600 m）的CTD观测。俄罗斯联邦科学和高等教育部地球天球委员会对远征研究提供了支持。
