Gravimetry is an important geophysical method for remote sensing of sub-surface geological structures and systems via detection of mass and/or density changes. Applications are both academic and industrial. Currently, gravimetry surveys are carried out using sensors that are very sensitive, but also heavy and expensive. Both specifications make gravimetric studies expensive and practically very difficult, especially for airborne surveys. A new miniature gravity sensor called Wee-g has been developed in Glasgow which is small enough to enable a wider range of survey techniques such as on drones. The two primary objectives of the research project will be to carry out a spatial gravimetry survey around the Mount Meager Volcanic Complex and continuous monitoring of the nearby landslides at Mount Currie. Both surveys will provide us with new insight into the structures and activity around each site, and also test the use case of Wee-g in such extreme environments. The work carried out in Canada in will be carried out as part of on-going natural hazards monitoring and a community outreach programme to involve First Nation Canadians in hazard monitoring.

重力测量是通过检测质量和/或密度变化来遥感地下地质结构和系统的重要地球物理方法。应用包括学术和工业。目前，重力测量是使用非常灵敏的传感器进行的，但也笨重且昂贵。这两种规范都使得重量分析研究成本高昂且实际上非常困难，特别是对于机载测量而言。格拉斯哥开发出了一种名为 Wee-g 的新型微型重力传感器，该传感器足够小，可以支持更广泛的测量技术，例如无人机。该研究项目的两个主要目标是在米格山火山群周围进行空间重力测量，并持续监测柯里山附近的山体滑坡。这两项调查将为我们提供对每个站点周围的结构和活动的新见解，并测试 Wee-g 在此类极端环境中的用例。加拿大开展的工作将作为持续的自然灾害监测和社区外展计划的一部分，让加拿大原住民参与灾害监测。
