Integrated geophysical imaging and inversion for georadar and seismic exploration

通过这个提议，我描述了我的研究小组在探索地壳最浅部分方面所期望取得的科学进展。具体而言，我们将通过georadar方法的进步实现古火山流测定和冰下流测绘，并将描述拟议碳捕获和储存（CCS）站点的抑制介质。在georadar中，我们的目的是通过开发一个新的采集平台来捕获比现在更高分辨率的数据。拟议的平台集成了优秀的便携性和先进的测量与传统的georadar单位。凭借出色的数据质量，我们将通过调整我们在高级地震处理、成像、反演和高性能计算（HPC）方面的丰富专业知识，开发突破性的地质雷达成像。我们将使用我们的突破性技术来回答有关火山流和火山管道系统在月球的爱达荷州火山口的起源的关键问题。与此同时，我们将把我们的新设备和技术部署到当地的一个冰冻湖泊和当地的冰川上，进行基冰成像实验。我们希望将这些短途旅行用作在努纳武特的Borup Fjord Pass进行长期探索的模拟实验--那里有一个国际公认的火星和木星卫星（木卫二）上可能形成生命的硫磺泉的模拟物。我们提出的先进地质雷达具有重要的星系意义，是绘制这些泉水的冰下管道系统的天然工具。我还介绍了我们提出的研究到地震特性在Priddis，阿尔伯塔。近地表特征描述在那里拟议的碳捕获和储存地点至关重要。正如我们提议为地质雷达所做的那样，我们将调整我们的地震和HPC专业知识，并在岩石刚度测量的近地表测绘方面取得突破性进展。它们将用于地震成像以及联合地震和重力绘图。长远来说，我们希望将这项技术应用于斜坡稳定性（灾害）评估。

With this proposal, I describe the scientific advances that my research group expects to make in exploring the shallowest part of the Earth's crust. Specifically, we will enable paleo-volcanic flow determination and sub-glacial flow mapping through advancement of the georadar method, and we will characterize the hold-down medium of a proposed Carbon Capture and Storage (CCS) site. In georadar, our intent is to capture much higher resolution data than is done now through development of a new acquisition platform. The proposed platform integrates excellent portability and advanced surveying with conventional georadar units. With exceptional data quality in hand, we will develop breakthrough georadar imaging through adaption of our substantial expertise in advanced seismic processing, imaging, inversion, and high-performance computing (HPC). We will use our breakthrough technologies to answer key questions regarding the origin of volcanic flows and volcanic conduit systems at Craters of the Moon, Idaho. Simultaneously, we will deploy our new equipment and techniques to a local frozen lake and to local glaciers for experiments in basal-ice imaging. These excursions we hope to use as analogue experiments for longer-term exploration at Borup Fjord Pass, Nunavut - home to an internationally recognized analogue for possible life-forming sulphur springs on Mars and on a moon of Jupiter (Europa). With significant galactic implications, our proposed advanced georadar is a natural tool for mapping the sub-glacial plumbing system of these springs. I also describe our proposed research into seismic characterization at Priddis, Alberta. Nearsurface characterization is critical at a proposed Carbon Capture and Storage site there. As we propose to do for georadar, we will adapt our seismic and HPC expertise and make breakthrough advances in nearsurface mapping of rock stiffness measurements. They will be used in seismic imaging, and joint seismic and gravity mapping. In the longer-term, we hope to adapt this technology for use in slope stability (hazard) assessment.
