Atlantic Ocean. Ocean exploration is a part of oceanography describing the exploration of ocean surfaces. Notable explorations were undertaken by the Greeks, the Phoenicians, the Romans, the Polynesians, Phytheas, the Vikings, Arabs and the Portuguese. Scientific investigations began with early scientists such as James Cook, Charles Darwin, and ...
The First World Ocean Assessment of 2015 showed that the ocean is important for the climate and support of life on the whole planet, and that critical ocean systems are under threat, making the exploration and mapping of the ocean a key environmental goal to facilitate understanding of the dynamics of ocean systems and the changes that are ...
Deep-sea exploration is the investigation of physical, chemical, and biological conditions on the ocean waters and sea bed beyond the continental shelf, for scientific or commercial purposes.
Marine geophysics uses techniques largely employed on the continents, from fields including exploration geophysics and seismology, and methods unique to the ocean such as sonar. Most geophysical instruments are used from surface ships but some are towed near the seafloor or function autonomously, as with Autonomous Underwater Vehicles or AUVs.
Polynesian navigators thus employed a wide range of techniques including the use of the stars, the movement of ocean currents and wave patterns, the patterns of bioluminescence that indicated the direction in which islands were located, the air and sea interference patterns caused by islands and atolls, the flight of birds, the winds and the ...
The International Seabed Authority (ISA) regulates all mineral-related activities in international waters and has granted 31 exploration licenses so far: 19 for polymetallic nodules, mostly in the CCZ; 7 for polymetallic sulphides in mid-ocean ridges; and 5 for cobalt-rich crusts in the Western Pacific Ocean.

Marine geology or geological oceanography is the study of the history and structure of the ocean floor. It involves geophysical , geochemical , sedimentological and paleontological investigations of the ocean floor and coastal zone .
