天空晴朗,没有一丝风的痕迹。现在的气温大约是-35℃,正是进行海洋声学实验最理想的时机。这里是加拿大北极圈群岛中最北边的岛屿。寒冷让人战栗,但它却塑造了大面积静止、牢固的冰面,这个近乎凝固的世界,为科学家们提供了一个在温和海域无法享受到的实验环境。 2000年的春天,一支科学考察队在此开始了历时一个月的海洋声学系列实验,研究监听声音在北冰洋厚厚的冰层和冻土中如何传递和消失。考察队的目的地是位于艾勒斯米亚岛北部海岸,一个被称为警戒站 The sky is clear, there is no trace of a trace of wind. The current temperature is about -35 ℃, which is the best timing for marine acoustic experiments. This is the northernmost island in the Canadian Arctic Circle. The chill feels trembling, but it shapes a large area of ​​still, solid ice, a nearly frozen world that provides scientists with an experimental environment that can not be enjoyed in temperate waters. In the spring of 2000, a team of scientific expeditions started a month-long series of experiments on marine acoustics to study how the sound of sniffing was transmitted and disappeared in the thick ice and frozen earth of the Arctic Ocean. Expedition team is located on the northern coast of Ellerslie, one is called a warning post
