Marine Species Monitoring & Environmental Stewardship

Welcome to the US Navy's Marine Species Monitoring Program web portal.  This website serves as an online portal providing access to news items, blog posts, reports, data, and updates on current monitoring projects, as well as information on the background of the program and U.S. Navy's investments in marine species research and monitoring (see About).

As stewards of the sea, the U.S. Navy is committed to protecting the environment while defending freedom. The short video below provides an overview of the program, and additional informational brochures and videos highlighting specific monitoring projects can be found on the Outreach page.  You can also check out the Navy's Stewards of the Sea Facebook page.
