Oceanographic Instrumentation

加州大学圣地亚哥分校的斯克里普斯海洋学研究所将获得几个航海系统和海洋仪器项目，放在一个共享使用设备池中。这一设备的维护是为了在该机构操作的四艘研究船上使用或与之配合使用。1989年期间，这些船的运行时间表的很大一部分是为了支持nsf赞助的研究项目。该仪器还将增加船舶和机构支持研究和工程活动的能力。仪器包括：-用于实时采集和显示大型数据集的船上数据管理系统和组件；-用于可靠收集和连续测量地下环流特征的多普勒电流分析器备件；-多开合网系统环境传感器。-CTD增强功能，用于获取海水电导率和温度随深度的详细剖面；-盐度瓶用于存储海水样品；-Niskin瓶用于收集水柱中不同深度的离散海水样品；-水炮和降压器用于声学地震剖面系统升级；-用于单通道声学剖面的高速拖缆，-用于确定仪器组件相对于地面或海底位置的精密声学ping仪，以及用于收集海底测深和沉积剖面数据的-12 khz回声测深系统。加州大学在购买这台设备上分摊费用。上述仪器将增加该组织支持nsf赞助的研究和工程项目的能力。

The Scripps Institution of Oceanography of the University of California at San Diego will acquire several sea-going systems and items of oceanographic instrumentation to be placed in a pool of shared use equipment. This equipment is maintained for use on or in association with the four research vessels operated by the institution. A substantial part of the ships' operating schedules during 1989 is in support of NSF-sponsored research projects. The instrumenta- tion will also increase the capabilities of the ships and of the institution to support research and engineering activities. The instrumentation includes: -Shipboard data management systems and components for real- time acquisition and display of large data sets, -Doppler Current Profiler spares for reliable collection and continuous measurements of subsurface circulation features, -Environmental sensors for multiple-opening and closing net system. -CTD enhancements for obtaining detailed profiles of seawater conductivity and temperature as a function of depth, -Salinity bottles for storing seawater samples, -Niskin bottles for collecting discrete seawater samples at various depths in the water column, -waterguns and depressors for an acoustic seismic profiling system upgrade, -High-speed streamer for single-channel acoustic profiling, -Precision acoustic pingers for determining position of an instrument package relative to the surface or seafloor, and -12-kHz echosounder system for collecting data on seafloor bathymetry and sedimentary profiles. The University of California is cost sharing in the acquisition of this equipment. The instrumentation described above will increase the capability of the organization to support NSF-sponsored research and engineering projects.
