摘要

2023 年 11 月初,"姆斯蒂斯拉夫-凯尔迪什院士 "号考察船完成了对喀拉海的第 92 次科学考察。俄罗斯科学院海洋学研究所考察队在第 92 次科学考察中的主要工作领域(考察队队长,俄罗斯科学院院士米哈伊尔-弗林特)是北极生态系统的气候趋势和累积的环境风险[1]。此次考察的多学科研究目标之一是通过 335 mkm 的 Manta neuston 网络收集微塑料样本,以评估其数量和在喀拉海结冰期间在海面的分布模式。VNIRO 科学家在 2018 年 8 月 7 日《VNIRO 与 IO RAS 研究活动合作意向协议》和 2021 年 3 月 3 日《Rosrybolovstvo 与俄罗斯科学院 2021 年及以后联合科学研究计划》框架内开展的科学工作,更新了微塑料、纤维和其他 人为污染物在海湾、海湾和冰缘水域等不同海域的分布数据。2023 年 10 月的观测没有发现微塑料在调查水域范围内的定位和异常浓度。

Preliminary results of observations of microplastics during ice formation in the Kara Sea
In early November 2023, the 92nd scientific survey of the R/V "Academician Mstislav Keldysh" to the Kara Sea was completed. The main areas of work of the expedition of the Institute of Oceanology of the Russian Academy of Sciences in the 92nd scientific voyage (head of the expedition, Academician of the Russian Academy of Sciences, Mikhail Flint) are climatic trends and accumulated environmental risks in Arctic ecosystems [1]. One of the objectives of the multidisciplinary research of the expedition was to collect samples of microplastics by the Manta neuston network 335 mkm to assess its quantity and distribution pattern in the surface during ice formation in the Kara Sea. The scientific work carried out by VNIRO scientists within the framework of the Agreement of Intent on Cooperation in Research Activities between VNIRO and IO RAS dated 07.08.2018 and the Program of Joint Scientific Research of Rosrybolovstvo and the Russian Academy of Sciences for 2021 and Subsequent years dated March 3, 2021, allowed updating data on the distribution of microplastics, fibers and other anthropogenic pollutants in various areas of the sea, including its bays, gulfs and the waters at the edge of the ice. Observations in October 2023 did not reveal localization and abnormal concentrations of microplastics within the boundaries of the surveyed water area.
