Instrumentation for the Deployment of a Permanent Ocean floor Broadband Seismic System in Monterey Bay, in Coopertion with MBARI

加利福尼亚大学伯克利分校的研究人员将与蒙特利湾水族馆研究所（MBARI）的科学家合作，在蒙特利湾海面以下700-1200米之间的海底安装一个长期的三分量宽带地震仪系统。MBARI将提供数据记录仪、锂电池、船舶和ROV时间，并将建造地震仪外壳。美国国家科学基金会将提供一个海底地震包，包括3分量宽带地震仪、24位A/D转换器和自动平衡定心和调平系统。此外，政府亦会拨款进行软件修改/开发，以便将地震仪套件与记录系统连接起来。MBARI将提供工程时间，加州大学伯克利分校将提供宽带地震学、数据采集、遥测、处理和存档方面的专业知识。新的装置将补充宽带地震台站的陆基网络，并将提供1)更好的方位覆盖，从而改善发生在加州北部沿着圣安德烈亚斯系统的中到大地震的特征，2)提高对该板块边界深层结构的认识。将在发展长期全球海底地震观测站的计划范围内获得长期部署宽带系统的经验。

California-Berkley will collaborate with scientists at Monterey Bay Aquarium Research Institute (MBARI) to install a long-term three-component broadband seismometer system on the seafloor in Monterey Bay between 700-1200m below the sea surface. MBARI will provide data-logger, lithium batteries, ship and ROV time and will build the seismometer housing. NSF support will provide an ocean bottom seismic package including 3 component broadband seismometers, 24-bit A/D converter, and automatic gimbaled centering and leveling system. Funding is also provided for software modification/development to interface the seismometer package with the recording system. MBARI will provide engineering time and UC Berkeley will provide expertise in broadband seismology, data acquisition, telemetry, processing and archival. The new installation will complement the land-based network of broadband seismic stations and will provide 1) better azimuthal coverage and thereby improve the characterization of moderate to large earthquakes occurring in northern California along the San Andreas system, and 2) improved knowledge of the deep structure of this plate boundary. Experience in long term deployment of broadband systems will be gained in the context of plans for the development of long term global seismic sea floor observatories.
