Whale sightings during POLARSTERN cruise PS85 (ARK-XXVIII/2)

Data on whale distribution and abundance in the polar oceans is rather sparse, as implementing the standard surveying method, line-transect surveys, is challenging and costly....极地海洋中鲸类分布与丰度的相关数据相当匮乏，这是由于开展标准调查方法——线样带调查（line-transect surveys）——既极具挑战性，又成本高昂。
