哈德逊湾、詹姆斯湾、福克斯盆地和哈德逊海峡（“研究区域”）的季节性冰雪覆盖的沃茨与39个社区接壤，总人口约5万人，其中大多数是因纽特人或克里人。海冰是研究区域环境和文化的基石，但也是该地区日益增长的航运交通的主要障碍。本文回顾了研究区的海冰和航运情况，并分析了研究区近海和当地沃茨水域的海冰解体、结冰和开水季节的航运可达性。使用1980-2014年基于被动微波的数据分析了海上冰定时;使用1996-2016年加拿大冰服务冰图表检查了兰金入口、丘吉尔、Kuujjuarapik/Whapmagoostui和萨卢伊特附近的当地冰定时。开放水域的定义使用海冰浓度阈值，
The seasonally ice-covered waters of Hudson Bay, James Bay, Foxe Basin, and Hudson Strait ("the study area") are bordered by 39 communities with a total population of roughly 50,000 people, most of whom are Inuit or Cree. Sea ice is a cornerstone of the environment and culture of the study area but is also the main barrier to shipping traffic, which has been growing in the area. This paper presents a review of sea ice and shipping in the study area and an analysis of shipping accessibility as represented by the timing of breakup, freeze-up, and the open water season in its offshore and local waters. Offshore ice timing was analyzed using passive microwave-based data for 1980-2014; local ice timing near Rankin Inlet, Churchill, Kuujjuarapik/Whapmagoostui, and Salluit was examined using Canadian Ice Service ice charts for 1996-2016. Open water was defined using sea ice concentration thresholds of
