MODIS (Terra) True-Color (Bands 1,3,4) 250-m resolution visible image of the Sulu Sea acquired on 8 April 2003 at 0520 UTC. Four packets of large solitons are visible in the sunglint region. Imaged area is 370 km x 500 km. See Also: http://www.internalwaveatlas.com/Atlas2_PDF/IWAtlas2_Pg393_SuluSea2.pdf, http://earthobservatory.nasa.gov/IOTD/view.php?id=3586

An image of the surface wind speed derived from an Envisat Advanved Syntheric Aperture Radar (ASAR) Wide Swath image acquired on 24 September 2008 at 0235 UTC. The roughness of the sea surface from winds cause variations in the amount of radar energy returned. These variations can be related back to the wind speed.
