Oceanographic Instrumentation

罗德岛大学海洋学研究生院将购买几件海洋仪器，放入共用设备池中。该设备的维护是为了在R/V奋进号上使用或与R/V奋进号关联使用，R/V奋进号是一艘由NSF拥有并由大学运营的研究船。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大学支持研究和工程活动的能力。该仪器包括：-用于在采集实时数据时显示其的计算机终端，-用于测量水柱中的叶绿素和其他光学性质的荧光计，-CTD压力计，以增强获得海水电导率和温度随深度变化的详细轮廓，-用于侧扫回声测深仪系统的拖车和数字调制解调器，用于收集海底水深测量和沉积剖面数据，-无线电以太网连接，用于加强船舶技术支持小组和科学用户之间的科学数据传输和通信，以及-自重测试仪，用于在将仪器带到海上之前测试仪器的公差和校准。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 Graduate School of Oceanography at the University of Rhode Island 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 R/V ENDEAVOR, a research vessel owned by the NSF and operated by the university. 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 University to support research and engineering activities. The instrumentation includes: -Computer terminal for displaying real-time data as it is being collected, -Fluorometer for measuring chlorophyll and other optical properties in the water column, -CTD pressure gauge, to enhancement obtaining detailed profiles of seawater conductivity and temperature as a function of depth, -Towed vehicle and digital modem for a side scan echosounder system for collecting data on seafloor bathymetry and sedimentary profiles, -Radio ethernet link for enhancing scientific data transfer and communications amongst the technical support group and scientific users of the ship, and -Dead Weight tester for testing the tolerances and calibration of instrumentation before taking them to sea. The instrumentation described above will increase the capability of the organization to support NSF-sponsored research and engineering projects.
