Magnetotelluric data, Southern San Luis Valley, Colorado, 2006: Station 3

This dataset includes the magnetotelluric (MT) sounding data collected in 2006 in the Southern San Luis Valley, Colorado. The U.S. Geological Survey conducted a series of multidisciplinary studies, including MT surveys, in the San Luis Valley to improve understanding of the hydrogeology of the Santa Fe Group and the nature of the sedimentary deposits comprising the principal groundwater aquifers of the Rio Grande rift. The shallow unconfined and the deeper confined Santa Fe Group aquifers in the San Luis Basin are the main sources of municipal water for the region. The population of the San Luis Valley region is growing rapidly and water shortfalls could have serious consequences. Future growth and land management in the region depend on accurate assessment and protection of the region's groundwater resources.

本数据集包含2006年于美国科罗拉多州圣路易斯谷南部采集的大地电磁（magnetotelluric, MT）测深数据。美国地质调查局曾在圣路易斯谷开展一系列涵盖大地电磁测量的多学科研究，旨在深化对圣菲群水文地质特征以及构成里奥格兰德裂谷主要地下水含水层的沉积地层性质的认知。圣路易斯盆地内的浅层无压含水层与深层承压圣菲群含水层，是该区域市政供水的核心来源。圣路易斯谷地区人口增速迅猛，水资源短缺或将引发严重后果。该区域未来的发展与土地管理工作，均依赖于对当地地下水资源的精准评估与保护。
