This visualisation shows ocean surface currents around the world during the period from June 2005 to Decemeber 2007. The goal was to use ocean flow data to create a simple, visceral experience.
It was produced using NASA/JPL's computational model, Estimating the Circulation and Climate of the Ocean, Phase II or ECCO2. ECCO2 is a 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 visualisation.
The dark patterns under the ocean represent the undersea bathymetry. Topographic land exaggeration is 20x and bathymetric exaggeration is 40x.
My favourite bit is the equator at around 1.39.
"The oceans thru the eyes of Van Gogh", says one viewer.

I must down to the seas again, to the lonely sea and the sky,And all I ask is a tall ship and a star to steer her by, And the wheel's kick and the wind's song and the white sail's shaking, And a grey mist on the sea's face, and a grey dawn breaking.
I must down to the seas again, for the call of the running tide Is a wild call and a clear call that may not be denied; And all I ask is a windy day with the white clouds flying, And the flung spray and the blown spume, and the sea-gulls crying.
I must down to the seas again, to the vagrant gypsy life, To the gull's way and the whale's way where the wind's like a whetted knife; And all I ask is a merry yarn from a laughing fellow-rover And quiet sleep and a sweet dream when the long trick's over.
By John Masefield (1878-1967). (English Poet Laureate, 1930-1967.)
- From the Wikipedia entry on him: It was not until about the age of 70, that Masefield slowed his pace due to illness. In 1960, Constance died at 93, after long illness. Although her death was heartrending, he had spent a tiring year watching the woman he loved die. He continued his duties as Poet Laureate; In Glad Thanksgiving, his last book, was published when he was 88 years old. In late 1966, Masefield developed gangrene in his ankle, which spread to his leg, dying of the infection on 12 May 1967. According to his wishes, he was cremated and his ashes placed in Poets’ Corner in Westminster Abbey. Later, the following verse was discovered, written by Masefield, addressed to his ‘Heirs, Administrators, and Assigns’:
Let no religious rite be done or read In any place for me when I am dead, But burn my body into ash, and scatter The ash in secret into running water, Or on the windy down, and let none see; And then thank God that there’s an end of me.
