Oceanographic Instrumentation

夏威夷大学海洋和地球科学与技术学院将购买几件海洋仪器，放入共享设备池中。该设备的维护是为了在该机构运营的研究船MOANA WAVE上使用或与之关联使用。该船在1990年的运行计划中有很大一部分是为了支持国家科学基金会赞助的研究项目。该仪器还将提高该船和该机构支持研究和工程活动的能力。该仪器包括：-海-气相互作用传感器系统。将组装一个可运输的仪器包，以便连续测量空气温度和湿度、风速和风应力、传入的太阳和长波辐射、降雨率以及海洋温度和盐度，-用于改善多通道声学剖面系统的数据收集能力的高速拖缆，-用于增加共享使用、海上计算能力以及实时获取和显示大型数据集的16通道异步线路多路复用器，-用于测定海水样本盐度的精密盐度计，-用于同时精确测量几个化学参数的自动分析仪，以及事件定时控制器，其将提供用于标记输入数据集和用于协调地震剖面图中的事件序列的精确时间标准。夏威夷大学正在为购买这种设备提供相当大的成本分担。上述仪器将提高研究所支持NSF赞助的研究和工程项目的能力。

The School of Ocean and Earth Science and Technology at the University of Hawaii will acquire several 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 research vessel MOANA WAVE that the institution operates. A substantial part of the ship's operating schedule during 1990 is in support of NSF-sponsored research projects. The instrumentation will also increase the capabilities of the ship and of the institution to support research and engineering activities. The instrumentation includes: -An air-sea interaction sensors system. A transportable instrument package will be assembled to make underway, continuous measurements of air temperature and humidity, wind velocity and wind stress, incoming solar and long-wave radiation, precipitation rate, and sea temperature and salinity, -High-speed streamer for improving the data collection capabilities of a multi-channel acoustic profiling system, -16-channel asynchronous line multiplexer for increasing shared-use, sea-going computing capabilities and real-time acquisition and display of large data sets, -A precision salinometer for determining the salinity of seawater samples, -Autoanalyzer for making precision measurements of several chemical parameters simultaneously, and -an event timing controller that will provide a precision time standard for marking incoming data sets and for coordinating the sequence of events in seismic profiling. The University of Hawaii is providing considerable cost sharing for acquiring this equipment. The instrumentation described above will increase the capability of the Institution to support NSF-sponsored research and engineering projects.
