Time difference of arrival methods for acoustically localizing multiple marine mammals have been applied to recorded data from the Navy's Pacific Missile Range Facility in order to localize and track calls attributed to Bryde's whales. Data were recorded during the months of August-October 2014, and 17 individual tracks were identified. Call characteristics were compared to other Bryde's whale vocalizations from the Pacific Ocean, and locations of the recorded signals were compared to published visual sightings of Bryde's whales in the Hawaiian archipelago. Track kinematic information, such as swim speeds, bearing information, track duration, and directivity, was recorded for the species. The intercall interval was also established for most of the tracks, providing cue rate information for this species that may be useful for future acoustic density estimate calculations.
用于对多种海洋哺乳动物进行声学定位的到达时间差方法已应用于海军太平洋导弹靶场设施的记录数据，以定位和追踪布氏鲸的叫声。数据于2014年8月至10月期间记录，共识别出17条个体轨迹。将叫声特征与来自太平洋的其他布氏鲸发声进行了比较，并将记录信号的位置与夏威夷群岛已公布的布氏鲸目视目击地点进行了比较。记录了该物种的轨迹运动学信息，如游速、方位信息、轨迹持续时间和指向性。还为大多数轨迹确定了叫声间隔时间，为该物种提供了叫声率信息，这可能对未来的声学密度估计计算有用。
