北喀斯喀特活动边缘的增生楔沉积物中含有分布广泛的天然气水合物一直延伸到海底下几百米的深度。为了评估天然气水合物的长期能源潜力和它在全球气候变化及边坡稳定性中的作用,2005年9月IODP 311航次建立了一个详细的地质模型来解释水合物的形成与分解以及它与穿过大陆边缘流?
The Pleistocene wedge sediments in the margins of the North Cascades have widely distributed gas hydrates that extend to a depth of a few hundred meters beneath the ocean floor. In order to assess the long-term energy potential of gas hydrates and its role in global climate change and slope stability, a detailed geological model was established by IODP 311 in September 2005 to explain the formation and decomposition of hydrates and its relationship with wear Crossing the continental margin?
