Exploration Tools

Advancements in technology allow us to explore the ocean in increasingly systematic, scientific, and noninvasive ways. This allows us to expand our understanding of both the ocean and marine organisms. Visit this page to learn more about some of the technology used for deep-ocean exploration, including platforms such as vessels and submersibles, observing systems and sensors, and communication tools. Despite the many advances so far, there is still much to learn and explore.

NOAA Ship Okeanos Explorer

NOAA Ship Okeanos Explorer is the only U.S. federal vessel dedicated to exploring our largely unknown ocean for the purpose of discovery and the advancement of knowledge. In close collaboration with government agencies, academic institutions, and other partners, the NOAA Office of Ocean Exploration and Research conducts deep-ocean expeditions using advanced technologies on the Okeanos Explorer. From mapping and characterizing previously unseen seafloor to collecting and disseminating information about ocean depths, this work helps to establish a foundation of information and to fill data gaps needed to identify, understand, and manage key elements of the ocean environment.
