A Study of Bathymetric Mapping

1. 
How can ocean floor features be measured and mapped using current acoustical technology? Sonar. we send sound waves to the ocean floor and see how long it takes them to bounce and come back. Once we have how long it took and how fast the sound waves traveled we can find the distance. How can ocean floor maps be used in the commercial, military, and/or private sectors? For commercial use, water depth, finding fish, and determining ocean sediments. In the military, every peice of the ocean floor needs to be known to the military. 

2. 
Flat Abyssal Plain: instead of being rugged, like along the mid-ocean ridges, sediments fall almost like snow, creating a flat plain on the ocean floor

Underwater Seamount: An underwater mountain rising from the ocean floor and having a peaked or flat-topped summit below the surface of the sea.

Continental Shelf: A submerged border of a continent that slopes gradually and extends to a point of steeper descent to the ocean bottom. 

Submarine Canyon: any of a class of narrow, steep-sided valleys that originate on the continental shelf and cut into continental slopes and continental rises of the oceans

Mid-Ocean Ridge: A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics.

Island Arc System: an arc-shaped chain of islands, such as the Aleutian Islands or the Japanese Islands, usually lying at the edge of a Benioff zone, indicating volcanic activity where the oceanic lithosphere is descending into the earth's interior

Dancing of the Continents Activity

     I had previous knowledge of Pangea, without knowing the name, but I knew that all of the continents were once in a big jumble. I did not know where the continents were placed though, which I learned through this activity. I learned of how the continents moved with the theory's of Wegner, Hess, and whoever else came up with the last one.
     I assume scientists publish their findings, and if a scientists of a different nature disagrees with their findings then they show the proof to disprove it. For instance, Wegner's idea of Continental Drift was based on his scientific studying, but Hess had a different scientific expertise and had proof to disprove Wegner's theory.

Experimental Design

This trip would be about three weeks round trip, so I would need about three weeks worth of food and clothing. A lot of underwater divign equipment and since the clms breed at night, underwater flash lights. Submersibles in case the water is too deep to dive. The procedure would be hour long shifts by 1 scientist at a time. collecting samples and also watching the clams in there natural habitat.
