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.

摘要OppractOPP-01-07767提案被建议作为探索性研究（SGER）的小型赠款（SGER），以开发新的采样和测量方法和工具，可以在北极海洋冰盖下部署美国联合的美国 - 德国 - 德国探险队，以供Gakkel Ridge in Gakkel Ridge In In In gakkel Ridge 2001年8月/9月。当前的方法，例如挖泥，可能在冰覆盖的水域中取得成功，因此首席研究人员正在建议设计，测试和建造新的岩石采样器。 他还提议改造一个水热监测器，称为微型自主羽流录像机（MAPR）。 MAPR是由太平洋海洋环境实验室开发的，该实验室是为了增加机会或收集沿着海洋中部山脊和火山系统的水热羽流数据。该提案适用于SGER计划，因为尚未开发岩石采样器。 岩石采样器和经过改装的羽状录音机都没有在冰下进行测试。 因此，这些工具符合SGER标准：“未经测试和新颖的想法的初步工作”。如果一种或全部仪器在ICE下成功执行，那么北极计划将有几种新的且廉价的抽样设计。
