AbstractFornari 0525863The investigators will compile a comprehensive geological map of the East Pacific Rise from 9 25 to 9 55 N using high-resolution DSL-120A sidescan data, ABE and Alvin scanning altimetric data, and Alvin and WHOI TowCam observations, digital photographs and geochemistry of recovered samples. A detailed analysis and mapping of all the volcanic flow contacts, fissures and faults imaged will be analyzed. Constraints will be placed on erupted volumes, flow lengths, fault throws, and fissure spacing.The project seeks to advance knowledge of submarine ridges, and the resulting data will be shared with the community and public via outreach activities, using both a website and an available database. Students will also be involved with the research.

摘要Fornari 0525863研究人员将使用高分辨率 DSL-120A 侧扫描数据、ABE 和 Alvin 扫描测高数据、Alvin 和 WHOI TowCam 观测、数码照片和回收样本的地球化学数据，编制东太平洋海隆从 9 25 到 9 55 N 的综合地质图。 将对成像的所有火山流接触面、裂缝和断层进行详细分析和绘图。 喷发量、水流长度、断层距和裂隙间距将受到限制。该项目旨在增进对海底海脊的了解，所得数据将通过外展活动利用网站和可用数据库与社区和公众共享。学生也将参与这项研究。
