中国第12次北极科学考察(2021年)走航海漂垃圾监测数据

为掌握北极地区海面漂浮垃圾的赋存现状，中国第12次北极科学考察围绕“雪龙2"号船航线上的海面漂浮垃圾进行了观测，对了解调查区域内海漂垃圾污染程度具有重要科学意义。
本数据监测时间范围为2021年7月15日至9月23日之间，考察海区包括日本海、鄂霍次克海、白令海、楚科奇海、北冰洋等，共189个海面漂浮垃圾走航观测记录，主要考察水体中、大型漂浮垃圾的分布与组成情况，包括塑料瓶类、泡沫类、塑料袋类、网（渔）具类、木制类等海面漂浮垃圾，在雪龙船的航迹上进行全程观测，所有仪器设备均经过计量检定且在有效期内，质量控制符合有关规范要求。

To grasp the occurrence status of surface floating marine debris in the Arctic region, the 12th Chinese National Arctic Scientific Expedition conducted observations on surface floating marine debris along the cruise track of the Xuelong 2 research vessel, which is of great scientific significance for understanding the pollution level of marine floating debris in the survey area.

The monitoring period of this dataset is from July 15 to September 23, 2021. The surveyed sea areas include the Sea of Japan, Sea of Okhotsk, Bering Sea, Chukchi Sea, Arctic Ocean and other regions. A total of 189 underway observation records of surface floating marine debris were obtained, focusing on the distribution and composition of medium and large-sized floating marine debris in the water column, including plastic bottles, foam materials, plastic bags, fishing nets and gears, wooden items and other types of surface floating marine debris. The observations were conducted along the entire cruise track of the Xuelong 2 research vessel. All instruments and equipment have passed metrological verification and are within their valid periods, and the quality control meets relevant standard specifications.
