Watch, learn and connect: https://stanfordconnects.stanford.edu/ Monterey and Santa Cruz counties rely more heavily on groundwater than other regions. Professor Rosemary Knight's shares her research of surveying the aquifer for saltwater intrusion by using sentinel geophysics to proactively monitor groundwater management. Rosemary Knight, PhD '85, is the George L. Harrington Professor in the School of Earth Sciences and senior fellow, by courtesy at the Woods Institute for the Environment. Her research focuses on the development of geophysical methods to understand what's occurring in the top 100 meters of Earth. By acquiring images of the near-surface region, researchers can monitor systems and extract information to help inform decisions regarding the evaluation and management of groundwater resources. In 2000, she developed and still currently teaches The Water Course, where students complete projects describing the source, quantity, and quality of water in their hometowns to gain a perspective on water-related issues. She believes "geo-literacy" should be a requirement of all graduates. To that end, she pioneered I-Earth (Introduction to Planet Earth), a set of courses exploring the intersection of natural systems, social systems, and human expression. This Stanford+Connects micro lecture was filmed on location in Monterey, California. Stanford+Connects is a program of the Stanford Alumni Association.
