What is Oceanography: Definition and 26 Discussions

Oceanography (from the Ancient Greek ὠκεανός "ocean" and γράφω "write"), also known as oceanology, is the scientific study of the ocean. It is an important Earth science, which covers a wide range of topics, including ecosystem dynamics; ocean currents, waves, and geophysical fluid dynamics; plate tectonics and the geology of the sea floor; and fluxes of various chemical substances and physical properties within the ocean and across its boundaries. These diverse topics reflect multiple disciplines that oceanographers utilize to glean further knowledge of the world ocean, including astronomy, biology, chemistry, climatology, geography, geology, hydrology, meteorology and physics. Paleoceanography studies the history of the oceans in the geologic past. An oceanographer is a person who studies many matters concerned with oceans including marine geology, physics, chemistry and biology.

    Underwater acoustics: transmission loss at long distance

    Hi all, I have some problems to understand how to calculate the transmission loss at long distance, which model do I have to use? I was looking into the energy flux model (Weston model), but I didn't understand at what range I should switch from "mode stripping" to "single mode". I am working...

    Deriving the formula for tidal generating force TGF

    i have been asked to show that the TGF acting on a 1kg mass, on the surface of the Moon is equal to: TGF = 2g.e^2.(a/r^3) Where; g = 9.81 e = radius of the Earth a = radius of the Moon r = distance between the centres of the Earth and Moon.

    What is the impact of storms on submarines?

    Here is a scenario to further explain. Let's say I am traveling inside of a submarine. I travel within a depth of 100 to 600 feet deep or 4 to 19 atmospheres. How would I and my submarine be affected if there were a hurricane, tsunami, or hurricane above the ocean. Furthermore, does the...

    How Can Interacting with Experts Improve Online Learning?

    I just signed up today. I'm here because I've been using MOC's (Massive Online Courses) and other forms of online learning for a while now. A key flaw with any form of self learning is the lack of interfacing with your instructor/teacher. I browsed this website for a bit and quickly concluded it...

    How Ocean Waves Affect Beaches

    Hi I am currently looking for a topic to write my essay on. My first idea was to talk about how waves altered in different beaches. (With this I mean the shape of the waves) I don't know much about waves and I can't seem to find good info on the internet. If you think there isn't much to write...
