[quote]This visualization shows ocean surface currents around the world during the period from June 2005 through Decemeber 2007. The visualization does not include a narration or annotations; the goal was to use ocean flow data to create a simple, visceral experience.
This visualization was produced using NASA/JPL’s computational model called Estimating the Circulation and Climate of the Ocean, Phase II or ECCO2.. ECCO2 is high resolution model of the global ocean and sea-ice. ECCO2 attempts to model the oceans and sea ice to increasingly accurate resolutions that begin to resolve ocean eddies and other narrow-current systems which transport heat and carbon in the oceans.The ECCO2 model simulates 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. [/quote]
Questo affascinante e ipnotico video mostra i movimenti delle correnti oceaniche in superficie nell’arco di due anni e mezzo, ricostruite grazie ai rilevamenti della Nasa e al modello computazionale ECCO2. C’è poco da aggiungere dato che la bellezza dell’animazione parla da sola…
