A Multi-Frequency Sonar Study of the Monterey Canyon and Fan

PI开发了一种侧扫声纳成像系统 海底 该系统具有30和72 kHz的侧扫 换能器和3.5 kHz下视换能器。 这是一 国家的最先进的系统，一直在发展，因为 1986. 侧扫和多波束系统的使用有所增加 在过去的几年里，学术界有一个 需要了解和量化这些产生的图像 系统. PI建议收集各种声纳数据集 在为期28天的蒙特利峡谷巡游中。 的 该计划的目标是操作新的声纳系统， 一个以前绘制得很好的，通常可以预测的地质 学习新信息的类型和范围的环境 可以从这种遥感中获得的信息。 这 项目将开始，以取代主观的方法，目前 用于描述和绘制海底地貌及其沉积物 用定量技术覆盖。 该领域的现有数据包括：DeepTow和格洛丽亚II 声纳图像，地震反射数据，沉积物岩心，总数 海底水深测量覆盖范围，大约30，000张海底照片， 以及多次潜水。 该地区也是网站 NOAA、USGS、 蒙特雷湾水族馆研究所等。 因此，在本发明中， 这个地区是一个很好的位置比较和地面实况 各种底部传感系统。

The PI has developed a side-scan sonar system for imaging the seafloor. This system has 30 and 72 kHz side-scan transducers and a 3.5 kHz down-looking transducer. This is a state-of-the-art system that has been under development since 1986. The use of side-scan and multibeam systems has increased in the academic community in the past few years and there is a need to understand and to quantify the images produced by these systems. The PI proposes to collect a variety of sonar data sets during a 28-day cruise to the Monterey canyon area. The objective of the program is to operate the new sonar system in a previously well-mapped and generally predictible geological environment to learn the types and extent of new information that can be obtained from this type of remote sensing. This project will begin to replace the subjective methods presently used to describe and map seabem landforms and their sediment cover with quantitative techniques. Existing data in the area includes: DeepTow and Gloria II sonar imagery, seismic reflection data, sediment cores, total Seabeam bathymetric coverage, about 30,000 bottom photographs, and a number of submersible dives. The area is also the site of current and long-term observations by NOAA, the USGS, the Monterey Bay Aquarium Research Institute, and others. Thus, this area is a good location to compare and ground-truth the various bottom sensing systems.
