Bioacoustical Oceanography: Dual-Beam Acoustic Deployed on a Multiple Opening/Closing Net and Environmental Sensing System

伍兹霍尔海洋研究所和康奈尔大学将合作开展一项海洋科学仪器开发项目，通过增加双光束生物声呐系统和光纤电缆，升级MOCNESS（多开合网和环境传感器系统）。该项目是提高这些广泛使用的系统收集的数据质量的下一个合乎逻辑的步骤，这些系统用于研究浮游生物分布和生态学。双光束生物声呐将使科学家能够将声音信号与实际捕获的动物联系起来。通过能够修改基于并发数据的正在进行的采样程序，以及研究相对于网捕获的生物的小规模分布，将改进对动物分布的调查。来自生物声呐和环境传感器的数据流超过了目前使用的机电电缆的遥测能力。新系统将利用快速发展的光纤电缆技术，可以承载更大的数据流。该系统将在计划中的海洋科学研究活动中得到广泛应用。

Woods Hole Oceanographic Institution and Cornell University will collaborate on an ocean sciences instrumentation development project to upgrade a MOCNESS (Multiple Opening / Closing Net and Environmental Sensor System) by adding a dual beam bio-acoustic sonar system plus an electro-fiber optic cable. The project represents the next logical step in improving the quality of data collected by these widely used systems that are employed in studies of plankton distribution and ecology. The dual beam bioacoustic sonar will enable scientists to correlate acoustic signals with animals actually captured in the net system. Investigations of animal distributions will be improved by being able to modify ongoing sampling programs based on concurrent data, and study small scale distributions of organisms relative to what the net captured. The data stream from the bioacoustic sonar plus the environmental sensors exceeds the telemetry capability of currently used electro-mechanical cables. The new system will make use of rapidly advancing fiber-optic cable technology that can carry larger data streams. The system will have broad application in planned ocean science research initiatives.
