Acoustic whale tracking log of the 2013 Antarctic Blue Whale Voyage to the Southern Ocean

During the 2013 Antarctic Blue Whale Voyage Acousticians noted all whale calls and other acoustic events that were detected during real-time monitoring in a Sonobuoy Event Log. A written summary of the event log was recorded during data collection at approximately 15 minute intervals, and this summary comprises the Whale Tracking Log. - The acoustician on-duty recorded the average bearings or locations of each calling whale/group every 15 minutes in the written Whale Tracking Log. - Entries in the written Sonobuoy Tracking Log (on the bench in the acoustics workstation) also include total number of different whales heard in that 15 minute interval.- If multiple whales/groups were detected, then the acoustician on-duty, in consultation with the lead acoustician and/or voyage management designateded one of the whales the 'target' whale, and attempted to encounter this target first. - When targeting a whale/group, the acoustician on-duty continued to track all other whales/groups in the area as these tracked whales/groups may become the next target after obtaining concluding with the current target. Date: (UTC) written only at top of datasheetTime: (UTC) on the hour, 15 past, half past, and 15 to.Track: Unique identifier for each whale/group tracked in the past 15 minutes. Each track will have:Location:    Either an average bearing from a sonobuoy (eg 220 degrees from SB18) or a Lat/Lon from the most recent triangulationNotes:    What is the vessel action with respect to this tracked whale/group? (eg. Is this the current or previous 'target'? Are we presently photographing this whale? Did we finish photographing the whale?) Has the whale gone silent? Has this track crossed paths with another?

在2013年南极蓝鲸科考航次（Antarctic Blue Whale Voyage）期间，声学观察员通过声呐浮标事件日志（Sonobuoy Event Log），对实时监测中检测到的所有鲸类鸣叫声及其他声学事件进行了完整记录。
数据采集期间，每约15分钟便会生成一份事件日志的书面摘要，该摘要即构成鲸类追踪日志（Whale Tracking Log）。
- 当班声学观察员会在书面鲸类追踪日志中，每15分钟记录每只鸣唱鲸类/鲸群的平均方位或位置。
- 放置于声学工作站工作台的书面声呐浮标追踪日志（Sonobuoy Tracking Log）条目，还会包含该15分钟时段内监测到的不同鲸类总数量。
- 若检测到多只鲸类/多个鲸群，当班声学观察员将与首席声学观察员及/或航次管理团队协商，指定其中一只鲸类为“目标鲸”，并优先对该目标鲸开展追踪观测。
- 在针对某一鲸类/鲸群开展追踪时，当班声学观察员仍需持续追踪区域内的其他鲸类/鲸群，因为在完成当前目标的追踪观测后，这些被追踪对象可成为下一追踪目标。

日期：（协调世界时UTC）仅填写在数据表顶部
时间：（协调世界时UTC）需记录为整点、15分、30分及45分时刻
追踪编号（Track）：过去15分钟内每只被追踪鲸类/鲸群的唯一标识符。每条追踪记录包含以下内容：
位置（Location）：要么为来自声呐浮标的平均方位（例如：距声呐浮标SB18的220度方位），要么为最新三角测量得到的经纬度坐标
备注（Notes）：针对该被追踪鲸类/鲸群的船舶行动是什么？（例如：该个体是否为当前或过往“目标鲸”？我们是否正在对该鲸类进行拍摄？我们是否已完成该鲸类的拍摄？）该鲸类是否已停止鸣唱？该追踪路径是否与其他追踪路径存在交叉？
