Oceanographic Instrumentation, R/V Cape Hatteras

杜克大学海洋实验室将购买几件海洋仪器，放入共享设备池中。该设备在哈特拉斯角R/V号上使用或与R/V一起使用，这是一艘由美国国家科学基金会拥有并由杜克大学运营的研究船。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该机构支持研究和工程活动的能力。该仪器包括：-对赛尔舰载数据记录系统进行计算机和其他硬件升级，-尼斯金瓶，用于收集水柱中的离散样品；-带有晶体延迟单元的精密图形记录器，用于显示海底水深测量和沉积剖面的声学数据；-用于清除船上实验室的化学烟雾的通风柜，-10 kHz水听器，用于接收来自已部署的仪器组件的声学信号，-无振动工作台，在进行显微镜工作时抑制船舶振动，-潜水空气压缩机和潜水箱，为海上科学潜水作业提供安全可靠的可呼吸空气来源，和-无线电测向信标，以方便定位海上漂浮仪器。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 Duke University Marine Laboratory 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 CAPE HATTERAS, a research vessel owned by the NSF and operated by Duke 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 institution to support research and engineering activities. The instrumentation includes: -Computer and other hardware upgrades for the SAIL shipboard data logging system, -Niskin bottles for collecting discrete samples in the water column, -precision graphic recorder with crystal delay unit for displaying acoustically derived data of seafloor bathymetry and sedimentary profiles, -a fume hood for removing chemical fumes from the ship's laboratory, -10 kHz hydrophone for receiving acoustic signals from deployed instrumentation packages, -Vibration free table to dampen out ship vibrations while doing microscopy work, -Diving air compressor and dive tanks to provide a safe and reliable source of breathable air for scientific diving operations at sea, and -Radio Direction Finder beacons to facilitate locating floating instrumentation at sea. The instrumentation described above will increase the capability of the organization to support NSF-sponsored research and engineering projects.
