IODP Expedition 389 2nd post cruise meeting in Hawaii: coral reefs, coasts and volcanoes. From July 30 to August 3, 2025, the X389 science team gathered in Hilo, Hawaii, for our second post‑cruise meeting. This event brought together researchers from across the globe—both in person and online—to share preliminary findings, refine analyses, and plan future publications from the IODP X389 expedition. It was a great meeting but we did have the added complication of the tsunami generated by the Russian earthquake…
