Capitol Hill Ocean Week (CHOW), hosted by the National Marine Sanctuary Foundation, is the nation’s leading conference dedicated to ocean and Great Lakes policy. Each year, CHOW brings together a dynamic mix of policymakers, scientists, conservationists, business leaders, educators, students, and engaged citizens to explore the most pressing issues facing our blue planet. Through thoughtful dialogue, innovative ideas, and collaborative action, CHOW drives meaningful progress in the protection and sustainable management of our ocean and Great Lakes.

CHOW 2025 is free and open to the public, made possible by the generous support of our sponsors.
