摘要

白鲸在格陵兰岛东部沿岸很少见，最近的公认种群在斯瓦尔巴群岛附近。我们在此报告格陵兰东北部发生的一起成年白鲸（Delphinapterus leucas）被冰困住的事件。2023 年 4 月 21 日，在对北极熊（Ursus maritimus）进行目视航测时，在菲恩湖（Loch Fyne）（北纬 73°54'，西经 21°51'）观察到鲸鱼被困在坚冰中。鲸鱼的位置距离开阔水域（即冰群）100 千米，身体状况不佳。对 20 世纪初的文献进行回顾后，没有发现任何其他关于白鲸在格陵兰岛东部被冰困住的记录。

First recorded ice entrapment of a beluga whale (Delphinapterus leucas) in east Greenland

Beluga whales are rare along the coast of east Greenland and the closest recognized stock occurs around Svalbard. Here we report on an ice entrapment of an adult beluga whale (Delphinapterus leucas) in north-east Greenland. The whale was observed entrapped in the fast ice on 21 April 2023 in Loch Fyne (73°54’N, 21°51’W) during a visual aerial survey for polar bears (Ursus maritimus). The whale was located >100 km from open water (i.e., pack ice) and appeared in poor body condition. A literature review back to the early 1900s failed to produce any other records of beluga whale ice entrapments in east Greenland.

期刊介绍： Since 1982, Polar Research has been the international, peer-reviewed journal of the Norwegian Polar Institute, Norway''s central institution for research, environmental monitoring and mapping of the polar regions. Aiming to promote the exchange of scientific knowledge about the Arctic and Antarctic across disciplinary boundaries, Polar Research serves an international community of researchers and managers. As an open-access journal, Polar Research makes its contents freely available to the general public. Original primary research papers comprise the mainstay of Polar Research. Review articles, brief research notes, letters to the editor and book reviews are also included. Special issues are published from time to time. The scope of Polar Research encompasses research in all scientific disciplines relevant to the polar regions. These include, but are not limited to, the subfields of biology, ecology, geology, oceanography, glaciology and atmospheric science. Submissions from the social sciences and those focusing on polar management and policy issues are welcome. Contributions about Antarctica are particularly encouraged.
