The oceanography of Milne Fiord

尽管加拿大埃尔斯米尔岛北部海岸存在冰架和冰川舌，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冰架的崩塌和罕见的冰架堰塞湖（Epishelf湖）的消失。冰架湖是一层淡水覆盖在海水上，形成于冰架和海岸之间。埃皮谢尔湖曾经在埃尔斯米尔岛北部海岸的冰架边缘普遍存在，但随着最近冰架的崩塌，这样的湖泊只剩下一个。米尔恩峡湾的Epishelf湖随着时间的推移厚度减少，极易受到气候和海洋变暖的影响。我们将研究米尔恩峡湾及其Epishelf湖的海洋学，使用无人驾驶、无系绳水下机器人以及传统的现场数据收集技术。

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.
