NASA’s Perpetual Ocean animation

A couple of months ago AGU blogger Dan Satterfield posted a great article titled The Turbulence of Van Gogh and the Labrador Shelf Current.

For getting maps and art together, I thought it could not be topped. Then today, I stumbled into NASA’s Perpetual Ocean animation: beautiful!

From the original Source: This is an animation of ocean surface currents from June 2005 to December 2007 from NASA satellites. Watch how bigger currents like the Gulf Stream in the Atlantic Ocean and the Kuroshio in the Pacific carry warm waters across thousands of miles at speeds greater than four miles per hour (six kilometers per hour); how coastal currents like the Agulhas in the Southern Hemisphere move equatorial waters toward Earth’s poles; and how thousands of other ocean currents are confined to particular regions and form slow-moving, circular pools called eddies.

Color palettes for seismic structure maps and attributes

I created three color palettes for structure maps (seismic horizons, elevation maps, etcetera) and seismic attributes. To read about the palettes please check these previous blog posts:

The rainbow is dead…long live the rainbow! – Part 5 – CIE Lab linear L* rainbow
The rainbow is dead series – Part 7 – Perceptual rainbow palette – the method
The rainbow is dead series – Part 7 – Perceptual rainbow palette – the goodies

The palettes are available as plain ASCII files and also formatted for a number of platforms and software products:

Geosoft
Hampson-Russell
Kingdom
Madagascar
Matlab
OpendTect
Petrel
Seisware
Surfer
Voxelgeo

Please download them from my Color Palettes page and follow instructions therein.

Enjoy!
