Whale sightings during POLARSTERN cruise ANT-XXIII/10@en

Date/Time is given in UTC. Certainty of identification: definite if observer clearly identified the species. The number of individuals is binned according to the options given in the data acquisition software: 1, 2, 3, less equal 5, less equal 10, greater than 10, greater than 20. More precise values may exist, due to observer comments. See doi:10.1594/PANGAEA.692892 and doi:10.1594/PANGAEA.692880 for weather condition and doi:10.1594/PANGAEA.727457 for the sea surface oceanography.日期与时间采用协调世界时（UTC）标注。物种识别置信度：若观测者可明确辨识物种，则识别置信度为确定级。个体数量按数据采集软件预设的分组规则进行分箱：1、2、3、≤5、≤10、＞10、＞20。若观测者另有备注，则可能存在更精确的个体数量数值。气象条件相关数据参见DOI：10.1594/PANGAEA.692892与DOI：10.1594/PANGAEA.692880；海表海洋学相关数据参见DOI：10.1594/PANGAEA.727457。
