中国第34次南极科学考察（2017-2018年）普里兹湾海洋海飘垃圾调查数据

为掌握普里兹湾海域海面漂浮垃圾的赋存现状，中国第34次南极科学考察围绕“雪龙”号船航线上的海面漂浮垃圾进行了监测，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2017年11月9日至11月23日之间，考察海区主要为普里兹湾海域，共9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 marine surface floating debris in the waters of Prydz Bay, the 34th Chinese National Antarctic Research Expedition conducted monitoring of marine surface floating debris along the cruise track of the Xuelong research vessel. This work is of great scientific significance for understanding the pollution level of marine floating debris in the survey area.

The monitoring period of this dataset spans from November 9 to 23, 2017. The survey area mainly covers the waters of Prydz Bay. A total of 9 underway observation records of marine surface floating debris were obtained. The survey mainly focused on the distribution and composition of medium and large-sized floating debris in the water column, including plastic bottles, foams, plastic bags, fishing nets and gears, wooden items and other types of marine surface floating debris. All observations were conducted along the cruise track of the Xuelong. All instruments and equipment have passed metrological verification and are within their valid service periods, and the quality control meets relevant specification requirements.
