History of oceanography

Oceanography is one of the newest sciences to be developed. There is still so much knowledge to be gained from studying the ocean. The original oceanography could date back to the beginning of earth. When man first started to go into the ocean in search of recourses. The understanding gained of currents and tides was passed down for thousands of years until the original line with a detachable weight was created. This sounding was able to determine the depth of the water. Although it's accuracy was not very accurate it was the beginning to the sonar we are now able to use. Sonar is a recent development where we are able to take seabed surveys, underwater investigations and bathymetric seabed mappings. Since World War Two the research of the ocean has taken off. Although a still immature study the development of new tools is in constant motion.
