Ocean mapping involves using acoustics, satellites, light and imaging, and other technologies to collect data about characteristics and resources of the ocean. NOAA Ocean Exploration mapping operations focus on the collection of seafloor, sub-bottom, and water column data for depths below 200 meters (656 feet), primarily using shipboard systems in addition to other platforms such as remotely operated or autonomous underwater vehicles.
Ocean mapping is critical to ensuring that we have the information, products, and services to prepare for and prosper in an ever-changing environment. For example, ocean mapping data can provide the initial information needed to establish a baseline assessment of the ocean environment, support decisions to guide targeted exploration, support exploration of underwater natural and cultural resources, increase understanding of marine life and habitats to inform management decisions, and help us understand natural hazards such as earthquakes, landslides, and tsunamis.
During the 2016 Hohonu Moana: Exploring Deep Waters off Hawaiʻi expedition featured in this video, high-resolution mapping of the seafloor revealed features, such as seamounts, that we didn't even know existed before and provided the foundational information needed to plan exploratory dives.
