点击翻译按钮获取中文摘要

A request is made to fund additional and back-up instrumentation for the R/V Blue Heron, an 86 foot Coastal vessel owned by the University of Minnesota and operated by the Large Lakes Observatory as part of the University-National Oceanographic Laboratory System (UNOLS) research fleet. The proposal includes two requests:1) Spare CTD Sensors2) Water Purification SystemBroader Impacts: The principal impact of the present proposal is under criterion two, providing infrastructure support for scientists to use the vessel and its shared-use instrumentation in support of their NSF-funded oceanographic research projects (which individually undergo separate review by the relevant research program of NSF). The acquisition, maintenance and operation of shared-use instrumentation allows NSF-funded researchers from any US university or lab access to working, calibrated instruments for their research, reducing the cost of that research, and expanding the base of potential researchers.
