We propose to combine a programme of field measurements and novel numerical models to investigate topics in two areas: 1) the influence of climate, both past and present, on  the shape and rate of landscape change in regions of ice-rich permafrost in northern Canada and elsewhere; and 2) how 3D fracture networks in permafrost, shallow reservoirs, ocean muds, and other geological materials assemble, and what determines properties such as fracture connectivity, length, and aperture --which have critical utility in issues as diverse as CO2 sequestration and contaminant transport in groundwater.

我们建议结合联合收割机和新的数值模式来研究两个领域的主题：1）气候的影响，过去和现在，在加拿大北方和其他地方的冰丰富的永久冻土区的形状和景观变化的速度;以及2）永久冻土、浅储层、海洋泥浆和其他地质材料中的3D裂缝网络如何组装，以及决定裂缝连通性、长度和孔径等性质的因素--这些性质在二氧化碳封存和地下水污染物传输等各种问题中具有关键作用。
