Oceanographic Instrumentation

加州大学圣地亚哥分校斯克里普斯海洋研究所将购买几个远洋系统和海洋仪器，放入共用设备池中。该设备的维护是为了在该机构运营的四艘考察船上使用或与之联合使用。1989年期间，这两艘船的大部分运营计划都是为了支持国家科学基金会赞助的研究项目。该仪器还将提高舰船和机构支持研究和工程活动的能力。该仪器包括：-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，-用于可靠收集和持续测量地下环流特征的多普勒流剖面仪备件，-用于多开合网系统的环境传感器。-用于获得作为深度函数的海水电导率和温度的详细分布的CTD增强，-用于存储海水样本的盐度瓶，-用于在水柱中的不同深度收集离散海水样本的尼斯金瓶，-用于升级声学地震剖面图系统的水枪和压制器，-用于单通道声学剖面图的高速拖缆，-用于确定仪器包相对于地面或海底位置的精密声学脉冲探测仪，和-12千赫超声测深仪系统，用于收集有关海底水深和沉积剖面的数据。加州大学正在分担购买这种设备的成本。上述工具将提高该组织支持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.
