Expedition Report: EX2501, Papahānaumokuākea Mapping 3

A groundbreaking mapping expedition, EX2501, conducted by NOAA Ocean Exploration from October 19 to November 12, 2024, significantly advanced the understanding of the Papahānaumokuākea Marine National Monument. The expedition mapped an extensive area of 44,264 square kilometers of seafloor within the U.S. Exclusive Economic Zone, all at depths greater than 200 meters. This comprehensive mapping effort provides critical data for scientific research and conservation efforts in one of the most remote and ecologically significant marine regions on Earth. The expedition utilized advanced oceanographic technologies to capture detailed seafloor topography, contributing valuable insights into the geological and biological characteristics of this unique World Heritage Site.
