Despite the existence of ice shelves and glacier tongues along the northern coast of Ellesmere Island, Canada, for the majority of the past 4000 years recent atmospheric warming has contributed to collapse of the remaining ice shelves and the loss of rare ice-shelf dammed lakes (Epishelf lakes). An Epishelf lake is a layer of fresh water overlying seawater that forms between an ice shelf and the coast. Epishelf lakes were once prevalent along the ice shelf fringed northern coast of Ellesmere Island but with recent ice shelf collapse, only one such lake remains. The Epishelf Lake in Milne Fiord has reduced in thickness over time and is highly vulnerable to the impacts of climate and ocean warming. We will study the oceanography of Milne Fjord and its Epishelf lake using an unmanned, untethered, underwater robot as well as conventional field data gathering techniques.

尽管加拿大埃尔斯米尔岛北部海岸存在冰架和冰川舌状物，但在过去4000年的大部分时间里，最近的大气变暖导致了剩余的冰架坍塌和稀有的冰架堰塞湖(Epishellake)的消失。EPISHELL湖是在冰架和海岸之间形成的覆盖在海水上的一层淡水。厄尔斯费尔湖曾经盛行于埃尔斯米尔岛北部海岸边缘的冰架上，但随着最近冰架的坍塌，只剩下一个这样的湖。米尔恩湾的埃皮什菲尔湖的厚度随着时间的推移而减少，非常容易受到气候和海洋变暖的影响。我们将使用无人驾驶、无缆水下机器人以及传统的野外数据收集技术来研究米尔恩峡湾及其爱皮西尔湖的海洋学。
