Operation SWAB: Monitoring of Ship, Van, and Laboratory 14C and 3H Contamination

该提案要求为SWAB项目再提供5年的支持。SWAB计划已经进行了近30年，作为将船舶和相关货车和实验室的氚（3H）和放射性碳（14C）污染降至最低的机制。作为CLIVAR和IOCCP等全球海洋计划的一部分，SWAB计划建议继续运营，以尽量减少对参与测量14C和3H自然丰度的船舶的污染。更广泛的影响：本提案的主要影响在标准二下，为科学家提供基础设施支持，以使用该船及其共享使用的仪器来支持他们的国家科学基金会资助的海洋学研究项目（这些项目单独接受国家科学基金会相关研究项目的单独审查）。共享使用仪器的获取、维护和操作允许来自任何美国大学或实验室的nsf资助的研究人员为他们的研究访问工作、校准仪器，降低研究成本，并扩大潜在研究人员的基础。

This proposal asks for 5 additional years of support for the SWAB program. The SWAB program has been going on for nearly 30 years as the mechanism for keeping tritium (3H) and radiocarbon (14C) contamination of ships and associated vans and laboratories to a minimum. The SWAB program proposes to continue operations in order to minimize contamination on ships involved in measuring natural abundances of 14C and 3H as part of global ocean programs such as CLIVAR and IOCCP. Broader 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.
