Oceanographic Instrumentation: SeaMARC II Side-Scan Sonar Transducer and Electronic Spare Parts

该海洋仪器采购项目将允许为夏威夷大学的SEAMARC II侧扫声纳系统建造新的换能器阵列和购买电子备件。新的仪器将增加现有的共享使用设备池，这些设备可供该机构研究船的用户使用。SEAMARC II是一种声学海底测量系统，可以同时生成高质量的海底声纳图像和海底等高线图。一艘科考船以高达10节的速度拖着声学阵列，同时船上的计算机产生近乎实时的海底形态显示。这些数据对研究板块构造、洋中脊、大陆边缘和其他由美国国家科学基金会赞助的研究课题的地质学家和地球物理学家很有兴趣。费用分摊由夏威夷大学提供。

This oceanographic instrumentation acquisition project will allow the construction of new transducer arrays and purchase of electronic spares for the University of Hawaii's SEAMARC II side-scan sonar system. The new instrumentation will augment that already in a pool of shared use equipment that is made available to users of the institution's research vessel. The SEAMARC II is an acoustic seafloor survey system that simultaneously produces both high quality sonar images of the sea bed and bathymetric contour charts along a swath of the seafloor. An acoustic array is towed behind a research vessel at speeds up to 10 knots while on board computers produce near-real time displays of seafloor morphology. Such data is on interest to geologists and geophysicists studying plate tectonics, mid-ocean ridges, continental margins and other research topics sponsored by the NSF. Cost-sharing is being provided by the University of Hawaii.
