项目摘要

California faces a constant fresh water problem. This problem is intensified by its complex water geography. In other words, where California receives precipitation is as important as how much precipitation it receives. This project will investigate the history of where and why it rains in California over the past 3000 years. Knowing where and why it rains in California is critical to water management, water storage infrastructure, and water conveyance from regions of excess to regions of deficit. As the largest state economy in the United States, the health of California is important to the health of the United States. This proposal's goal is to investigate California's precipitation history as related to the position and strength of its North-South antiphased precipitation regime over the past 3000 years. To accomplish this goal, tubes of mud will be extracted from three lakes. Like a history book, these tubes of mud record California's precipitation history. The team will study the mud's physical, chemical, and biological properties to infer a history of floods, droughts, vegetation change, and fire activity. Training of students from groups historically underrepresented in Science, Technology, Engineering and Math is a key component of this study.

加州面临着持续的淡水问题。这一问题因其复杂的水域地理而加剧。换句话说，加州在哪里得到降水和得到多少降水一样重要。这个项目将调查过去3000年来加州哪里下雨以及为什么下雨的历史。了解加州的降雨地点和原因对于水资源管理、水储存基础设施以及从水资源过剩地区向水资源短缺地区的输水至关重要。作为美国最大的州经济体，加州的健康状况对美国的健康状况至关重要。该提案的目标是调查加州的降水历史，与过去3000年来南北反相降水制度的位置和强度有关。为了实现这一目标，将从三个湖中提取泥浆管。就像一本历史书，这些泥管记录了加州的降水历史。该团队将研究泥浆的物理，化学和生物特性，以推断洪水，干旱，植被变化和火灾活动的历史。对来自科学、技术、工程和数学领域历史上代表性不足的群体的学生进行培训是这项研究的一个关键组成部分。
