As part of FORCE BLUE’s National Marine Sanctuaries Tour of Duty, two veteran divers, Jonathan Schleyer and Terrence Tysall, joined NOAA’s Office of National Marine Sanctuaries and partners on an expedition to Papahānaumokuākea National Marine Sanctuary—a place sacred to Native Hawaiians and home to remarkable biodiversity and history beneath the waves. Their participation brought a unique combination of skill, professionalism, and teamwork to the mission, contributing to archaeological documentation, dive safety coordination, and media production.

Honoring History and Culture

Working alongside Michael Wilson of the Polynesian Voyaging Society (PVS), the team revisited a culturally and historically significant anchor and windlass site first discovered by PVS in 2021. Together, they produced high-resolution photogrammetry, 360° imagery, and traditional field documentation to create a comprehensive site plan that integrates Indigenous Knowledge and Native Hawaiian perspectives. This collaboration builds on NOAA’s memorandum of agreement with PVS and strengthens ongoing efforts to protect and interpret maritime and cultural heritage sites within the sanctuary.

Documenting Maritime Heritage

In addition to cultural site documentation, the team surveyed and recorded six historic shipwrecks and anchor sites, including the 19th-century Two Brothers whaling ship and the World War II–era USNS Mission San Miguel. These efforts help guide sanctuary management decisions, add to the National Anchor Database, and preserve irreplaceable stories from Hawai‘i’s maritime past.

Advancing Reef Science and Storytelling

The expedition also supported long-term coral reef monitoring led by Dr. Nancy Foster Scholar Kailey Pascoe, advancing understanding of reef health in this remote region. FORCE BLUE media specialist Jon Schleyer worked with NOAA’s film team to capture 6K cinematic video, drone footage, and 360° virtual reality content that will bring these discoveries to classrooms and communities across the country.

Continuing Service Through Conservation

Through this partnership, NOAA and FORCE BLUE are advancing the goals of the National Marine Sanctuaries Act and the EXPLORE Act (Expanding Public Lands Outdoor Recreation)—fostering stewardship, honoring cultural heritage, and connecting veterans and communities to ocean conservation.
