The study of marine geology dates back to the late 1800s during the 4-year HMS Challenger expedition. [1] [2] HMS Challenger hosted nearly 250 people, including sailors, engineers, carpenters, marines, officers, and a 6-person team of scientists, led by Charles Wyville Thomson.

This is because the field vector generated by the magnetized crust and the direction of the Earth's magnetic field vector are both measured by the magnetometers used in marine surveys. Because the Earth's field vector is much stronger than the anomaly field, a modern magnetometer measures the sum of the Earth's field and the component of the ...
Thermohaline circulation. 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.
The continental shelf of the United States is one of the largest examples of marine geology in the world, with thousands of miles of submarine land making up the various shelves of the collective. Each different shelf features different extents of continental shelves, from the long, elevated shelves of Alaska , to the short shelf of the Pacific ...
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. It shares objectives with marine geology , which uses sedimentological , paleontological , and geochemical methods.
Marine sediment, or ocean sediment, or seafloor sediment, are deposits of insoluble particles that have accumulated on the seafloor.These particles either have their origins in soil and rocks and have been transported from the land to the sea, mainly by rivers but also by dust carried by wind and by the flow of glaciers into the sea, or they are biogenic deposits from marine organisms or from ...
5-million-year history, representing the Lisiecki and Raymo (2005) LR04 Benthic Stack Sections of sedimentary cores from off Greenland. Marine isotope stages (MIS), marine oxygen-isotope stages, or oxygen isotope stages (OIS), are alternating warm and cool periods in the Earth's paleoclimate, deduced from oxygen isotope data derived from deep sea core samples.
