ABOUT KELLY'S WORK
Kelly Benoit-Bird is a marine biologist who uses sophisticated acoustic engineering techniques to explore the previously invisible behavior of ocean creatures at scales ranging from swarms distributed over many cubic kilometers to individual predators. The food web of ocean surface waters begins with microscopic creatures that serve as the source of food for tiny organisms (zooplankton) just large enough to generate an acoustic signature. Although zooplankton drift in response to ocean currents, Benoit-Bird has shown that they use their modest locomotive capacity to form swarms with distinct three-dimensional structures that change with feeding conditions. Using multi-frequency acoustic backscattering, she has been able to reconstruct the feeding patterns of swimming predators of zooplankton (known as nekton) as they first pass downward through a layer of zooplankton, then reverse course and pass through upward. Having precise data about the horizontal and vertical distribution of oceanic food webs opens a new path for understanding the complexities of marine ecology. Further up the food chain, Benoit-Bird has investigated and illuminated the behavior of mammalian predators such as spinner dolphins, which hunt nekton in small, coordinated groups. These groups follow a carefully choreographed sequence of movements, repeated many times, to minimize the opportunity for the prey to escape. Using advanced acoustic engineering technology that she has modified and optimized for applications specific to her research, Benoit-Bird is addressing long-unanswered questions and providing the marine ecology community with a clearer picture of the structure and behavior of food chains.

BIOGRAPHY
Kelly Benoit-Bird received a B.S. (1998) from Brown University and a Ph.D. (2003) from the University of Hawaii at Mānoa. She was a postdoctoral fellow at the Hawaii Institute of Marine Biology (2003–2004) before joining the College of Oceanic and Atmospheric Sciences at Oregon State University, where she is currently an associate professor of biological oceanography. Her scientific articles have appeared in such journals as Nature, Marine Biology, and the Journal of the Acoustical Society of America.

关于凯莉的工作
Kelly Benoit-Bird是一位海洋生物学家,他使用复杂的声学工程技术来探索以前看不见的海洋生物的行为,其规模从分布在许多立方公里的群落到单个捕食者。海洋表层水的食物网从微小的生物开始,这些生物是微小生物(浮游生物)的食物来源,其大小刚好可以产生声学特征。尽管浮游生物随洋流漂移,但Benoit-Bird已经表明,它们利用其适度的运动能力形成具有明显三维结构的群落,并随进食条件的变化而变化。利用多频声学后向散射,她已经能够重建浮游生物(称为nekton)的游泳捕食者的捕食模式,因为它们首先向下穿过浮游生物层,然后扭转方向向上穿过。拥有关于海洋食物网的水平和垂直分布的精确数据,为理解海洋生态学的复杂性开辟了一条新的道路。在食物链的更上游,Benoit-Bird研究并阐明了哺乳动物捕食者的行为,如飞旋海豚,它们以小型的、协调的群体来捕食尼科鱼。这些群体遵循精心编排的动作序列,重复多次,以尽量减少猎物逃跑的机会。Benoit-Bird使用先进的声学工程技术,对其研究的具体应用进行了修改和优化,她正在解决长期未解决的问题,并为海洋生态学界提供了一个关于食物链结构和行为的更清晰的图像。

个人简历
Kelly Benoit-Bird在布朗大学获得学士学位(1998),在夏威夷大学马诺亚分校获得博士学位(2003)。在加入俄勒冈州立大学海洋和大气科学学院之前,她是夏威夷海洋生物研究所的博士后研究员(2003-2004),目前是生物海洋学的副教授。她的科学文章出现在《自然》、《海洋生物学》和《美国声学学会杂志》等杂志上。
