FINAL POST

The semester course that was Oceanography had aspects of physics and geology.  Given that physics is in the ocean, and the ocean is in Earth, this should've been quite obvious.   I learned many new concepts and things in this class.  It started with the underwater observatory.  Believe it or not, people sometimes go out to the middle of the sea, dive down a few meters, and live in there for some time, to look at the sea, face to face.  There's also the history aspect of Oceanography; explorers like Christopher Columbus, Sir Francis Drake, and of course, Charles Darwin.  I did a project about Charles Darwin, talking about his journey all throughout the world on a ship known as The Beagle.  He went to the Galapagos Islands, and found some new species of birds.  And then there was the tracking hurricanes.  It was learned that most hurricanes happen in the Summer, take a couple hours to take form, and strike the east coast days later.  I did actually know most of that, though I wasn't very interested before then.  Another thing was the measuring the tides.  The moon has effects upon the ocean, and the tides are often high or low depending on time of day and the position of the moon.  And, lastly, there was the study of heat in water.  There is no cold, only less warm.  If the water has a lower temperature, it has higher density.  Deeper down in the ocean it is more dense and cold than it is up at the surface.
