The PI's request funding to develop a portable platform to collect Global Positioning System - Acoustic (GPS-A) measurements to measuring seafloor deformation. The proposed system will be internally powered and autonomous, capable of collecting GPS-A data for a minimum of 24 hours while unattended. It will have two thrusters guided by GPS to automatically maintain its lateral position above an array of acoustic transponders on the sea floor. It will be portable, self-contained and deployable from a variety of vessels to open access to regions wherever there are ships-of-opportunity.Broader Impacts: After the Sumatra, Chile and Japan earthquakes the need for more knowledge and tools in this area/discipline is even more apparent. To further enable research in this area, new tools are required to engender new science. If successful, GEOSPAR will bring new knowledge on earth's active process both in research and education, as well as a view of disaster prevention against large earthquakes and resultant tsunami. Has direct impact upon science goals of four major NSF supported efforts: GeoPRISMS, the Cascadia Initiative, Earthscope, and the OOI cabled observatory (along the Cascadia Subduction Zone).

国际和平研究所请求提供资金，以开发一个便携式平台，收集全球定位系统-声学测量结果，以测量海底变形。拟议的系统将是内部供电和自主的，能够在无人值守的情况下收集GPS-A数据至少24小时。它将有两个由GPS引导的推进器，以自动保持其在海底一系列声学应答器上方的横向位置。它将是便携的，自给自足的，可以从各种船只上部署，以打开通往任何有机会的船只的地区的通道。广泛的影响：在苏门答腊岛、智利和日本地震之后，对这一领域/学科的更多知识和工具的需求更加明显。为了进一步促进这一领域的研究，需要新的工具来产生新的科学。如果成功，GEOSPAR将带来关于地球在研究和教育方面的活跃过程的新知识，以及防止大地震和由此引发的海啸的灾害预防的观点。对国家科学基金会支持的四项主要工作的科学目标有直接影响：地球棱镜系统、卡斯卡迪亚倡议、地球望远镜和OOI有线天文台(沿着卡斯卡迪亚俯冲带)。
