Today's #InstagramTakeover comes from #ScienceCommunicationFellow Caitlyn Ogbaekwe. Caitlyn, a Marine Science Lecturer at Hawaii Pacific University, specializes in teaching students how to become seagoing scientists.

With our new @kongsbergasa EM304 multibeam sonar upgrade, we can map deeper and more efficiently than ever before! This is especially critical as we will be exploring some of the deepest parts of the ocean in 2026. Learn more in our #blog: bit.ly/4etrb2F

Today #EVNautilus sets sail on its first expedition of 2026! Join us as we map the #seafloor between #Hawaii and #Guam, using our brand-new multibeam sonar technology! Learn more about this expedition in our #blog: bit.ly/4ewaL9D @oceanexplorer @ccom_jhc

𝗖𝗵𝗶𝗻𝗹𝗲 𝗧𝗼 𝘁𝗵𝗲 𝗗𝗲𝗲𝗽 𝗦𝗲𝗮: 𝗗𝗶𝗻𝗲́ 𝗘𝗱𝘂𝗰𝗮𝘁𝗼𝗿 𝗞𝗶𝗺 𝗘𝘁𝘀𝗶𝘁𝘁𝘆 𝗦𝗲𝘁 𝗳𝗼𝗿 𝗧𝘄𝗼 𝗚𝗹𝗼𝗯𝗮𝗹 𝗘𝘅𝗽𝗹𝗼𝗿𝗮𝘁𝗶𝗼𝗻𝘀 This summer, while many students and educators enjoy a well-earned break, Diné science teacher Kim Etsitty of Navajo Pine High School will be embarking on two extraordinary expeditions that will take her across some of the most remote regions of our planet. Originally from Chinle and a graduate of Chinle High School, Etsitty has spent more than a decade teaching Diné students and helping bridge Indigenous knowledge with Western science. She also serves as an Indigenous Science Curriculum Writer and a NASA Solar System Ambassador, inspiring the next generation of scientists and explorers. Beginning in June, Etsitty will sail aboard the Exploration Vessel Nautilus as a 2026 Lead Science Communication Fellow with the Ocean Exploration Trust. In this leadership role, she will help mentor new fellows while sharing real-time discoveries as scientists map the seafloor between Hawaiʻi and Guam. She previously sailed aboard Nautilus in 2024 and now returns as one of only a handful of lead fellows selected nationwide. In July, she will continue her journey as a 2026 Grosvenor Teacher Fellow with the National Geographic Society, traveling to Greenland and Iceland to explore Arctic environments and bring those experiences back to her students and community. Etsitty often speaks about connecting ocean science to Diné history and culture, reminding students that the shells and coral found in Navajo jewelry tell the story of ancient oceans that once covered parts of Diné Bikéyah. “Kim Etsitty represents the very best of the Navajo Nation. She is showing our young people that no dream is too big and that Diné knowledge and scientific discovery can go hand in hand,” said President Buu Nygren. Community members can follow her upcoming expedition through Nautilus Live, where viewers will be able to watch livestreams, interact with scientists, and experience ocean exploration in real time. Learn more at NautilusLive.org. Congratulations, Kim, and thank you for carrying Diné excellence from the red rocks of Chinle to the oceans of the world.

OET warmly welcomes Jhen Allison Paguiligan Seguiwan, a student at @SUUtbirds, to our NA178 Pacific Mapping expedition as a #seafloormapping intern! Learn more about Jhen, from #AmericanSamoa, via Samoa News: bit.ly/4uquVqm

Happy #WorldOceansDay! We're thrilled to launch our 2026 #oceanexploration season soon and to share our discoveries of the global ocean with the world through live streaming at NautilusLive.org. Learn more about the 2026 season via @PostGuam: bit.ly/3RKYV2R

If you haven’t heard, we've been working closely with Ocean Exploration Trust to develop a deep-sea, project-based learning curriculum. The curriculum, called Depths of Discovery, invites students into the world of those who are dedicated to understanding the deep ocean (and the science behind it all!). Units are being field-tested, and we are incorporating teacher feedback. Teachers report that kids love hearing from the many people on board the @EVNautilus and are drawn to their genuine excitement and curiosity. We hope to inspire students to be stewards of the ocean and are excited to offer this curriculum soon to classrooms nationwide. Stay tuned.

After 13 years of excellent service and 2,269 days at sea, OET is retiring our trusty EM302 multibeam. During this time, we successfully mapped 1.3 million km2 of seafloor: an area roughly the size of California three times over! @Seabed2030
