In this paper, a preliminary climatic description of the long-term offshore drift ice characteristics in the northern Barents Sea has been investigated from 1987 to 2016 based on the satellite ice motion datasets from National Snow and Ice Data Center (NSIDC) and reanalysis ice thickness datasets from National Centers for Environmental Prediction (NCEP)-Climate Forecast System Reanalysis (CFSR) and Climate Forecast System Version 2 (CFSv2). Both the ice velocity and thickness conditions have been studied at the three fixed locations from west to east. Annual and monthly drift ice roses indicate that the directions from WSW to SE are primarily prevailing, particularly in winter months. Besides, the annual ice speed extremums exceeding 40 cm s^–1 mostly occur in the southerly directions from November to April. For the ice thickness, results reveal that it is prominently distributed in a thicker interval between 70 and 120 cm, and a thinner interval between 20 and 70 cm. The annual thickness maxima approximately range from 90 to 170 cm, primarily occurring from May to June, and demonstrate a light decreasing trend.

本文基于美国国家冰雪数据中心（NSIDC）的卫星冰运动数据集和重新分析的冰层厚度，对1987年至2016年巴伦支海北部远海长期浮冰特征进行了初步的气候描述。来自国家环境预测中心（NCEP）-气候预报系统重新分析（CFSR）和气候预报系统版本2（CFSv2）的数据集。在从西到东的三个固定位置都研究了冰速和厚度条件。每年和每月的流冰玫瑰表明，主要从WSW到SE的路线特别是在冬季。此外，年冰速极值超过40 cm s ^–1大部分发生在11月至4月的偏南方向。对于冰的厚度，结果表明，它以70至120 cm的较厚间隔和20至70 cm的较薄间隔显着分布。年厚度最大值大约在90至170厘米之间，主要发生在5月至6月，并且显示出轻度下降的趋势。
