With the launch of the NASA SEASAT altimetric satellite on June 26, 1978 and the NOAA TIROS-N on October 13 of the same year a new area in oceanography was born. This revolution must be defined as both a scientific and technological advancement, where each step has led to new understandings of the world's oceans. From the first detailed maps from SEASAT, which showed changes of meters in the hills and valleys of the ocean surface due to the Earth's gravitational pull, to TOPEX/Poseidon, which captured centimeter changes of the ocean surface due to the heating and cooling associated with El Nino/La Nina, the science has been coupled to the technology. Additionally infrared satellites, such as the NOAA series of polar orbiting platforms, have revealed ocean currents that are as dynamic as the atmosphere, complete with storm like features known as eddies. Other sensors, such as SeaWIFs and QuikSCAT have provided global data on both the productivity, as well as surface winds, of the world's oceans.
