9730813 Cormier A night field program using the Autonomous Benthic Explorer (ABE) to survey the seafloor on a previously-funded cruise to 17oS on the East Pacific Rise is proposed. The previously-funded cruise will include ALVIN dives, DSL-120 side-looking sonar, wax coring, and dredging operations to determine the petrological, geochemical, and volcanological aspects of this mid-ocean ridge environment. The use of the ABE should allow the better identification of lavas flows, their morphology, dimensions, and along axis continuity. A magnetometer has been added to the ABE for the purpose of identifying recent, highly magnetized feeder dikes and, potentially, non-magnetized feeder dikes.

9730813 Cormier 建议开展一项夜间实地计划，使用自主底栖探索器 (ABE) 在先前资助的东太平洋隆起至南纬 17 度的巡航中调查海底。 先前资助的巡航将包括 ALVIN 潜水、DSL-120 侧视声纳、蜡取芯和疏浚作业，以确定这个大洋中脊环境的岩石学、地球化学和火山学方面。 ABE 的使用应该可以更好地识别熔岩流、其形态、尺寸和沿轴的连续性。 ABE 中添加了磁力计，用于识别最近的高度磁化的支线堤坝以及可能的非磁化的支线堤坝。
