ABSTRACT 063744 (Soule)Intellectual Merit: This research identifies and characterizes the link between magma supply and plate boundary processes at the Lucky Strike segment of the mid-Atlantic Ridge in a slowly spreading seafloor setting. A better understanding of crustal architecture and seafloor construction are main research targets. Research consists primarily of a field program aboard a French ship and working closely with French collaborators, with land-based data analysis taking place at Woods Hole Oceanographic Institution in the US. High-resolution TowCam imaging of individual lava flows, faults, and fissures along the central valley and environs of the mid-Atlantic Ridge will be carried out and integrated with magnetic, submersible, bathymetric, and other field data collected on the cruise. The research will yield micro-topographic profiles, the collection of lava samples for analysis, and near-bottom magnetic data. Three locations on the Lucky Strike segment are slated for study. Outcomes of the work consist of a high-resolution map of the Lucky Strike area and models of seafloor construction and axial volcanism on a slow-spreading mid-ocean ridge.Broader Impacts: This work supports an early career scientist at the Woods Hole Oceanographic Institution in Massachusetts and engaged summer undergraduates in research. It also includes significant interaction with French scientists of the InterRidge community and includes cross training of a French graduate student in a US laboratory. Maps and images will be linked to GIS will be available over the web where it can be accessed by scientists and the public; and geochemical data will be archived in the web accessible geochemical database, PetDB.

摘要：本研究在缓慢扩张的海底环境中，识别并描述了大西洋中脊Lucky Strike段岩浆供应与板块边界过程之间的联系。更好地了解地壳结构和海底构造是主要的研究目标。研究主要包括在一艘法国船上进行实地项目，并与法国合作者密切合作，在美国伍兹霍尔海洋研究所进行陆地数据分析。沿着中央山谷和大西洋中脊的周边地区，将对单个熔岩流、断层和裂缝进行高分辨率的TowCam成像，并将其与在巡航中收集的磁、潜水、测深和其他现场数据相结合。这项研究将产生微地形剖面，收集熔岩样本进行分析，以及近底部的磁数据。幸运时光部分的三个地点将进行研究。这项工作的成果包括一张Lucky Strike地区的高分辨率地图，以及海底构造和缓慢扩张的洋中脊上的轴向火山活动模型。更广泛的影响：这项工作支持了马萨诸塞州伍兹霍尔海洋研究所的一位早期职业科学家，并吸引了暑期本科生进行研究。它还包括与InterRidge社区的法国科学家的重要互动，包括在美国实验室对一名法国研究生进行交叉培训。与地理信息系统相连的地图和图像将通过网络提供，供科学家和公众使用；地球化学数据将存档在可通过网络访问的地球化学数据库PetDB中。
