Video: Perpetual Ocean
NASA Goddard Area Flight Middle initially launched this video in 2012. Known as Perpetual Ocean, it reveals ocean floor currents around the globe through the interval from June 2005 by way of December 2007. The visualization doesn’t embody a narration or annotations. It simply helps you to benefit from the sensational motion of the oceans on this watery planet of ours. NASA stated in 2012:
… the objective was to make use of ocean circulation information to create a easy, visceral expertise.
I feel they did it! Do you?
How NASA created the video
That is certainly one of my all-time favourite NASA movies. Right here’s an evidence of its creation, from NASA:
This visualization was produced utilizing NASA/JPL’s computational mannequin referred to as Estimating the Circulation and Local weather of the Ocean, Section II or ECCO2. ECCO2 is a high-resolution mannequin of the worldwide ocean and sea-ice. ECCO2 makes an attempt to mannequin the oceans and sea ice to more and more correct resolutions that start to resolve ocean eddies and different narrow-current techniques which transport warmth and carbon within the oceans.
The ECCO2 mannequin simulates ocean flows in any respect depths, however solely floor flows are used on this visualization. The darkish patterns beneath the ocean signify the undersea bathymetry [ocean floor]. Topographic land exaggeration is 20x and bathymetric exaggeration is 40x.
By the way in which, there are two variations of this video, a 20-minute model and a 3-minute model. You possibly can see each in high definition here.
