What is the difference between oceanography and marine geology?

There's lots of overlap between the two fields, but oceanography is generally considered to be the broader discipline, encompassing biology, chemistry, and physical studies of the ocean. Marine geology is a branch of oceanography that specifically focuses on the geology of the ocean floor, including plate tectonics and paleoceanography. In summary, oceanography is a broad discipline that includes biology, chemistry, and physical studies, while marine geology is a more specialized field within oceanography that focuses on the geology of the ocean floor.

Marine Geology is a branch of Oceanography. Marine Geology is the study of the geology of the ocean floor including plate tectonics and paleoceanography.

Oceanography covers the watery bits; marine geology covers the rocky bits.

No Greg is right, oceanography includes marine geology:

Oceanography...covers a wide range of topics, including marine organisms and ecosystem dynamics; ocean currents, waves, and geophysical fluid dynamics; plate tectonics and the geology of the sea floor;

Marine geology is the study of sediment cores, mainly in the Ocean Drilling Program. to measure numerous proxies and try to make sense of it. See also this.

In my very personal opinion, accumulated over the years, it's the most misunderstood part of Earth science.

Edit: That's challengeable of course.

This is a pretty reasonable summary...depends of course on what a particular department or group wants to be called.
 

1. What is marine geology?

Marine geology is the study of the Earth's oceanic crust, sediment deposits, and the processes that shape them. It is a branch of geology that focuses on understanding the evolution and current state of the ocean and its relationship to the rest of the Earth.

2. How is marine geology different from other branches of geology?

Marine geology differs from other branches of geology in that it specifically focuses on the geological processes and features found in the ocean and on the ocean floor. This includes studying the physical, chemical, and biological aspects of the ocean and how they interact with each other.

3. What techniques and tools do marine geologists use?

Marine geologists use a variety of techniques and tools to study the ocean floor, such as sonar mapping, sediment sampling, and underwater cameras. They also use remote sensing technologies, such as satellite imagery and geophysical surveys, to study the ocean's surface and subsurface features.

4. How does marine geology contribute to our understanding of the Earth?

Marine geology plays a crucial role in our understanding of the Earth's history, climate, and natural resources. By studying the ocean floor and its geological processes, we can gain insights into past climate patterns, plate tectonics, and the distribution of natural resources such as oil and gas.

5. What are some current research topics in marine geology?

Some current research topics in marine geology include studying the impacts of climate change on the ocean, exploring the potential for deep-sea mining, and investigating the role of the ocean in the carbon cycle. Marine geologists are also researching ways to mitigate the effects of natural hazards, such as tsunamis and hurricanes, on coastal communities.
