Map the seafloor of the Pacific with Guam-based ocean explorer at the Guam Museum's second Ocean Night

After welcoming around 60 participants last month, the Guam Museum is excited to invite the community to attend its second installment of “Puengen Tåsi Siha” (CHamoru: ocean nights) on Friday, June 27, 2025, at 6pm. 

During the event, the island community will get to connect with Shelterihna Alokoa, a Pacific Islands University alumna, community volunteer educator, and 2025 Ocean Exploration Trust (OET) Science Communication Fellow (SCF) sailing onboard Exploration Vessel (E/V) Nautilus. 

Exploring the Offshore Marianas (NA172) will map previously unexplored areas of the seafloor around the Mariana Islands, the Federated States of Micronesia, and the Solomon Islands. This expedition will also involve the deployment of Argo floats to support global ocean monitoring efforts and topside surveys by trained seabird observers who will assess the diversity and abundance of seabirds offshore. 

Through a virtual call held live with explorers on the ship, participants will learn more about seafloor mapping, seabird surveys, and life at sea, as well as opportunities to get involved in deep-sea exploration. 

Other Marianas-based educator explorers will also be a key part of the event. 2025 Science Communication Fellows Amanda Dedicatoria, a freelance science writer, and Shannon Seleen, a D.L. Perez Elementary School teacher, will facilitate the event in person and field questions from the audience.

In addition to Alokoa’s live connection from sea, Dedicatoria and Seleen will talk about their experience on Mattingan (CHamoru: deep ocean): Mariana Arc Volcanic Exploration (NA171), which explored the volcanic seafloor within and around the Mariana Trench Marine National Monument in May 2025.  

Following the presentations, participants will be able to interact with outreach booths from local marine and environmental conservation programs, support local artists, and other community organizations. 

Ocean Exploration Trust, a nonprofit founded by Dr. Robert Ballard, operates with a mission to explore the unknown parts of the ocean, seeking out discoveries in geology, biology, and hydrography while pushing the boundaries of STEAM education and technological innovation. OET promotes science, technology, engineering, art, and mathematics (STEAM) education worldwide using the excitement of exploration and innovation to inspire the next generation of scientists and engineers. NautilusLive.org acts as a 24-hour live-streaming web portal bringing expeditions from the field to explorers on shore via telepresence technology and social media. Viewers can tune in LIVE at any time to watch expeditions.
