InSAR Measurements of Terrain Stabilit in Canada’s North應用InSAR技術測量加拿大北部的地質穩定性
The Issue
議題
In Canada’s North,
people reside, work and travel on terrain often underlain by frozen soil or permafrost.
在加拿大北部,
人們居住、工作、旅遊的土地經常是結凍的土地或是永凍層
The seasonal freeze and thaw of the surface active layer leads to cyclical subsidence and heave,
地表層由於季節性的凍結與溶解，導致週期性的沉降與隆起
which represents a significant challenge to the design and maintenance of northern infrastructure.
這彰顯了北部地區基礎建設設計與維護的挑戰性
Today, as the Arctic warms and permafrost degrades,
there is an increased urgency to understand this change and give Northerners the tools to adapt.
如今，北極暖化及永凍層降
北方人需要工具去了解這些變化及適應
