Integrated geophysical imaging and inversion for georadar and seismic exploration

在这一建议中，我描述了我的研究小组在探索地壳最浅部分方面期望取得的科学进展。具体来说，我们将通过地质雷达方法的进步实现古火山流测定和冰下流测绘，我们将描述拟议的碳捕获和储存（CCS）站点的保持介质。在地质雷达方面，我们的目的是通过开发新的采集平台来获取比现在更高分辨率的数据。所提出的平台集成了优秀的便携性和先进的测量与传统的地质雷达单元。凭借出色的数据质量，我们将利用我们在先进地震处理、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技术。我们将利用我们的突破性技术来回答关于火山流的起源和火山导管系统在月球陨石坑，爱达荷州的关键问题。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，进行基底冰成像的实验。我们希望将这些短途旅行用作模拟实验，以便在努纳武特地区的博鲁普峡湾进行长期探索-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所在地。由于具有重要的银河系意义，我们提出的先进地质雷达是绘制这些泉的冰下管道系统的天然工具。我还介绍了我们在艾伯塔省Priddis进行的地震表征研究。近地表表征对于拟建的碳捕集与封存基地至关重要。正如我们在地质雷达上所做的那样，我们将利用我们的地震和高性能计算专业知识，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测绘。从长远来看，我们希望将这项技术应用于边坡稳定性（危害）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.
