AbstractOPP-01-07767This proposal is being recommended as a Small Grant for Exploratory Research (SGER) to develop new sampling and measurement methods and tools that can be deployed under the Arctic Ocean ice cap for a joint U.S. - German expedition to the Gakkel Ridge in August/September 2001. The current methods, such as dredging, may not be successful in ice-covered waters, so the Principal Investigator is proposing to design, test and build a new rock sampler. He is also proposing to retrofit a hydrothermal monitor, known as the miniature autonomous plume recorder (MAPR). The MAPR was developed by the Pacific Marine Environmental Lab to increase opportunities or collecting hydrothermal plume data along mid-ocean ridge and volcanic systems.This proposal is appropriate for consideration under the SGER program because the rock sampler has not been developed. Neither the rock sampler nor the retrofitted plume recorder have ever been tested under ice. Therefore, the instruments meet the SGER criterion, "preliminary work on untested and novel idea." If one or all of the instruments perform successfully under ice, then the Arctic program will have several new and inexpensive sampling devises.

本建议被推荐为探索性研究小额赠款（SGER），以开发新的取样和测量方法及工具，用于2001年8月/9月在北冰洋冰盖下进行的美国-德国联合考察加克尔海岭。 目前的方法，如疏浚，可能无法成功地在冰覆盖的沃茨，所以首席研究员建议设计，测试和建立一个新的岩石采样器。 他还提议改造一个热液监测器，称为微型自主羽流记录器（MAPR）。 MAPR是由太平洋海洋环境实验室开发的，目的是增加沿大洋中脊和火山系统沿着收集热液羽流数据的机会。 岩石取样器和改装的羽流记录器都没有在冰下进行过测试。 因此，该仪器符合SGER标准，“初步工作未经测试和新颖的想法。“如果一个或所有的仪器在冰下成功运行，那么北极计划将有几个新的和廉价的采样装置。
