A Second Generation Multi-Beam Echo-Sounding System for the Research Vessel BERNIER

该项目将为正在转换为哥伦比亚大学拉蒙特-多尔蒂地质观测站操作的研究船的BERNIER提供船上科学支持设备，并专门用于支持海洋科学研究。船上科学支持设备计划为船舶设备提供资金，这些设备被认为是正确和安全进行海洋科学研究所必需的。该计划为甲板设备（包括用于部署和检索科学仪器的绞车系统）、导航设备（如雷达、陀螺仪和地球卫星接收器）提供支持，以确定研究地点的位置。通信设备，包括无线电收发机和卫星收发机，用于话音和科学数据通信，以及其他设备，如探测仪，用于探测海底。项目主管Jeffrey K. Weissel博士、Dennis E. Hayes博士和William B. F. Ryan博士在监督船上设备的采购和安装方面具有丰富的经验，完全有资格指导该项目。该项目将允许该机构获得并安装第二代多波束回声探测系统，以几乎两倍于美国学术研究船上现有系统的空间分辨率绘制海底地图。这第二代系统可以进一步绘制几乎2.5倍宽的带状地图。大范围测绘能力的更高效率转化为研究船操作的大量成本节约。

This project will provide shipboard scientific support equipment for the BERNIER undergoing conversion to a research vessel to be operated by Columbia University Lamont-Doherty Geological Observatory and dedicated to use in support of ocean science research. The Shipboard Scientific Support Equipment Program provides funds for ship equipment deemed essential to the proper and safe conduct of ocean science research. This Program provides support for such items as deck equipment including winch systems for the deployment and retrieval of scientific instruments, navigational equipment such as radars, gyroscopes and earth satellite receivers to pin point the location of research sites, communication equipment including radio transceivers and satellite transceivers for voice and scientific data communications and other equipment such as echo-sounders to interrogate the sea bottom. The Project Directors, Dr. Jeffrey K. Weissel, Dr. Dennis E. Hayes and Dr. William B. F. Ryan are fully qualified to direct this project having had considerable experience in overseeing the acquisition and installation of shipboard equipment. This project will allow the institution to acquire and install a second generation multi-beam echo-sounding system to map the ocean floor with nearly twice the spacial resolution of existing systems installed on U.S academic research ships. This second generation system can furthermore map a swath almost two and a half times as wide. the greater efficiency of the broad swath mapping capability translates into substantial cost savings for research vessel operations.
