1st dataset animation:

Using data from several satellite altimeters, a finer picture of the ever-changing height of the oceans is revealed. Swirling currents called eddies pepper the global ocean. Like small pock-marks in sea surface height, these eddies are found in every major ocean basin. Near the Equator, the eddies give way to fast moving features called Kelvin Waves. When they build up in the Pacific, these waves can usher in a phenomenon known as El Nino, which happens when warm water and high sea levels move into the Eastern Pacific along the Equator. Occurring every 3 to 4 years, El Nino can have a big impact on weather across the globe, brining extra rainfall to the American Southwest and even affecting hurricanes in the Atlantic Oceans.

2nd dataset animation:

This animation illustrates sea surface height anomalies (SSHA) from 1950 to 2009. The pre TOPEX/Poseidon (1992) SSHA data are derived from a cyclo-stationary EOF tuned to the AVISO SSHA and then applied to tide gauge data.

3rd dataset animation:

This visualization shows global ocean surface currents from June 2005 through December 2007. It was produced using model output from the joint MIT/JPL project: Estimating the Circulation and Climate of the Ocean, Phase II or ECCO2. ECCO2 uses the MIT general circulation model (MITgcm) to synthesize satellite and in-situ data of the global ocean and sea-ice at resolutions that begin to resolve ocean eddies and other narrow current systems, which transport heat and carbon in the oceans. ECCO2 provides ocean flows at all depths, but only surface flows are used in this visualization. The dark patterns under the ocean represent the undersea bathymetry. Topographic land exaggeration is 20x and bathymetric exaggeration is 40x.
