This visualization shows ocean surface currents around the world during
the period from June 2005 through Decmeber 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.
