Pacific Quest: Mapping and Exploring the Pacific

Pacific Quest: Mapping and Exploring the Pacific is a collaborative federal science campaign to map, explore, and characterize the deep ocean in the central and western Pacific. Through the exploration of largely unknown deep-ocean areas, the campaign provides timely, reliable, public data essential for understanding and managing our ocean environment, including places with the potential for deep-sea mineral resources.
