2025 NEPDEP Expedition – Seamounts and Mapping

The overarching objective of this multidisciplinary joint expedition (NorthEast Pacific Deep-sea Exploration Project –NEPDEP ) is to support the management, monitoring, and conservation of proposed and existing marine conservation areas. We will map and visually explore the geology and life on seamounts of the Tang.ɢ̲wan · ḥačxʷiqak · Tsig̱is Marine Protected Area (TḥT MPA) and Tuzo Wilson Seamount Complex (TWSC). Seamounts are underwater mountains that rise more than 1,000 meters from the seafloor that are Ecologically and Biologically Significant Areas (EBSAs) as they are deep-sea ‘hotspots’ for biological productivity and diversity. A highlight will include returning to the newly discovered, hydrothermally active, home of incredible coral gardens, deep-sea nursery on the summit of NEPDEP 58 Seamount. Join us as we share the joy of discovery and our incredible remotely operated vehicle imagery of the deep by watching our dives live (https://www.nepdep.com/2025expeditionseamounts) and by following our social media @nepdep_, #nepdep!
