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 .
Oceanography (from Ancient Greek ὠκεανός (ōkeanós) 'ocean' and γραφή (graphḗ) 'writing'), also known as oceanology, sea science, ocean science, and marine science, is the scientific study of the ocean, including its physics, chemistry, biology, and geology.
In oceanography, terrigenous sediments are those derived from the erosion of rocks on land; that is, they are derived from terrestrial (as opposed to marine) environments. [1] Consisting of sand , mud , and silt carried to sea by rivers , their composition is usually related to their source rocks; deposition of these sediments is largely ...

Evan Forde, a Miami native, was the first Black oceanographer to explore the Atlantic’s deep canyons in a two-man submersible in 1979. ... including marine geology and geophysics, atmospheric ...
Plate tectonics was a suitable explanation for seafloor spreading, and the acceptance of plate tectonics by the majority of geologists resulted in a major paradigm shift in geological thinking. It is estimated that along Earth's mid-ocean ridges every year 2.7 km 2 (1.0 sq mi) of new seafloor is formed by this process. [50]
Marine geophysics is the scientific discipline that employs methods of geophysics to study the world's ocean basins and continental margins, particularly the solid earth beneath the ocean.
Central Jersey native Joe Gradone grew up less than 40 miles from the Atlantic Ocean, but his fascination with oceanography first surged while studying geology as an undergraduate at the ...
