This Senate resolution designates October 23, 2026, as "National Marine Sanctuary Day" to honor the anniversary of the Marine Protection, Research, and Sanctuaries Act of 1972. The resolution celebrates the National Marine Sanctuary System, which protects ocean, coastal, and Great Lakes environments across the United States, and recognizes their role in conserving biodiversity, protecting endangered species, and preserving historic shipwrecks and cultural sites. The resolution encourages Americans to visit and support these marine sanctuaries and calls on the National Oceanic and Atmospheric Administration to partner with communities to complete designations of new sanctuaries. There is no direct funding associated with this resolution, as it is a ceremonial measure that simply establishes a national observance day and expresses the Senate's support for marine conservation efforts.
