Funds are provided to support the U.S. contribution to a collaborative program with Norwegian investigators to sample the extinct Aegir Ridge, followed by onshore geochemical analyses and geodynamic modeling. Norwegian co-PIs have extensive experience in geophysical field work and geologic sampling in this region and will provide ~10 days of ship time as well as the necessary equipment to dredge the exposed scarps of the Aegir ridge axis. Major- and trace-elements studies, as well as isotope (Pb, Nd, Hf, Sr) analyses will be performed and 3D numerical models of continental rift-hotspot interaction will be developed which will define the physical conditions needed to explain the data, including quantitatively testing of the possible geologic scenarios.The project provides training for students and promotes international collaboration.

提供资金来支持美国对与挪威调查人员进行合作计划的贡献，以品尝灭绝的Aegir Ridge，然后进行陆上地球化学分析和地球动力学建模。挪威的副案例在该地区的地球物理现场工作和地质抽样方面具有丰富的经验，并将提供约10天的船舶时间以及必要的设备，以驱除Aegir Ridge Axis的裸露的陡峭陡坡。 将开发主要和微量元素研究以及同位素（PB，ND，HF，SR）分析，并将开发大陆裂谷互动相互作用的3D数值模型，该模型将定义解释数据所需的物理条件，包括定量测试可能的地球场景。项目为学生提供了培训，为学生提供了培训和促进学生的国际合作。
