California Ocean and Coastal Ecosystems


California has 1,100 miles of shoreline and 220,000 square miles of state and federal oceanic habitat, featuring one of the world’s most diverse marine ecosystems. A portal to explore the health of our ocean ecosystems is being developed. As one component of this effort, follow thelink below to learn more about tide pools.

A project of the West Coast Governors Alliance on Ocean Health (WCGA) to increase discovery and connectivity of ocean and coastal data and people to better inform regional resource management, policy development, and ocean planning. The Portal informs priority West Coast ocean issues such as tracking sources and patterns of marine debris, adaptation to sea-level rise, understanding impacts of ocean acidification on our coasts, and marine planning.
