Funds are provided to evaluate the deformation on the Gorda plate using recently-acquired bathymetric data which needs to be processed and interpreted to understand the nature of seafloor structures and how they relate to deformation processes. The study is a unique opportunity to assess interplate deformation where there is a large amount of high-quality data available. The PI's will analyze the excellent large multibeam bathymetry dataset collected over the Gorda plate and, in parallel, numerical models will be run by a collaborator that will be integrated with the findings of the PIs. It could provide important structural and tectonic results with important implications for other studies.

为利用最近获得的测深数据评估戈尔达板块的变形提供了资金，需要对这些数据进行处理和解释，以了解海底结构的性质及其与变形过程的关系。这项研究是评估板间变形的独特机会，因为有大量高质量的数据可用。PI将分析在戈尔达板块上收集的优秀的大型多波束测深数据集，同时，数值模型将由一个合作者运行，该合作者将与PI的结果相结合。它可以提供重要的构造和构造结果，对其他研究具有重要意义。
