The image was captured by the MODIS instrument on NASA’s Aqua satellite. (Click on the picture for a larger version with more features.)
Here’s an explanation, from NASA’s Ocean Color Image Gallery:
The above image of the ocean east of Tasmania in December, 2004 may not depict the ocean as we might expect to see it, but it does serve to highlight (in a completely unscientific fashion) subtle differences in water color that result from varying distributions of such scattering and absorbing agents in the water column as phytoplankton, colored dissolved organic matter, suspended sediment, bubbles, etc.
It may be unscientific. But it certainly is visually stunning.
