This study will develop methods for inferring the emplacement conditions of submarine lava flows based on their surface morphology and texture, using laboratory simulations, modeling and mapping of undersea flows. Laboratory experiments will use polyethylene glycol in tanks of cold sucrose to simulate silicate lavas. Dredge samples will be used to estimate eruption rates of flows from their crystal content and rheological properties. The results will ultimately lead to constraining models of ridge evolution.

这项研究将利用实验室模拟、海底流动建模和测绘，根据海底熔岩流的表面形态和结构，开发推断海底熔岩流侵位条件的方法。实验室实验将使用聚乙二醇罐中的冷蔗糖来模拟硅酸盐熔岩。疏浚样品将被用来根据其晶体含量和流变性来估计水流的喷发速度。这一结果最终将导致脊线演化的约束模型。
