The 20th century sees the most rapid development. Modern technological development was used(advanced technology: computer, instruments and sensors, satellites. Military role in the development of oceanography. Echo sounders sense the contour of the seafloor by sending sound waves to the bottom and measures time for sound waves to get back to ship. 3 dimensional views are from multibeam bathymetry sonar. Adcp- acoustic doppler current profiler- used to measure how fast water is moving across the entire water column. Conductivity, temperature, depth (ctd)- primary took for determining essential physical properties of sea water. Territorial water- from 3 to 12 nautical miles. Exclusive economic zone- extends 200 nautical miles from the shore. The big bang is the term used to describe the beginning of the universe, probably about 14 billion years ago. As the universe expanded, it cooled, eventually allowing the formation of atom, which then formed galaxies and stars. Density- the mass per unit volume of a substance.
