Measuring The Behavior of Beaked Whales and Their Responses to Sound Using a Digital Recording Tag

0427577约翰逊本奖项授予马萨诸塞州的伍兹霍尔海洋研究所，为综合研究对突吻鲸，特别是Ziphius cavirostris和Mesoplodon sp.，对人类活动的声音特别敏感的物种。 研究技术将包括实地记录发声和环境参数，从而提供关于深度和进食方式、心率和发声等生理参数以及潜水和水面行为的直接信息。 在第二年，实地工作将包括受控暴露实验，使用声纳来解决动物对不同频率范围和振幅的声音的反应。 预计这些数据将有助于更好地了解突吻鲸大规模搁浅的可能原因，这些搁浅与海洋岛屿附近的人为声音，特别是军事声纳有关。

0427577JohnsonThis award to Woods Hole Oceanographic Institution in Massachusetts provides support for the an integrated effort to investigate environmental factors and behavior important to the life cycle of beaked whales, especially Ziphius cavirostris and Mesoplodon sp., species that have shown indications of special sensitivity to anthropogenic sound. Research techniques will include field efforts to record vocalizations together with environmental parameters, and thus provide direct information on depth and manner of feeding, physiological parameters such as heart rate and vocalization, and behavior when diving and at surface. In the second year, the field effort will include controlled exposure experiments, using sonars to address responsiveness of the animals to sound in different frequency ranges and amplitudes. It is anticipated that these data will lead to a better understanding of possible causes of mass strandings of beaked whales that have been associated with anthropogenic sound, especially military sonars, in the vicinity of oceanic islands.***
