Whale sightings during POLARSTERN cruise ANT-XXIII/3@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.544836 and doi:10.1594/PANGAEA.544828 for weather condition and doi:10.1594/PANGAEA.666160 for the sea surface oceanography.所有日期与时间均采用协调世界时（UTC）标注。物种鉴定置信度：若观测者可明确识别物种，则鉴定结果为确定。个体数量按照数据采集软件提供的选项进行分箱分级：1、2、3、≤5、≤10、>10以及>20。鉴于观测者附带的备注信息，可能存在更为精确的个体数量数值。气象状况相关数据可参见DOI：10.1594/PANGAEA.544836与DOI：10.1594/PANGAEA.544828；海面海洋学相关数据可参见DOI：10.1594/PANGAEA.666160。
