This scene, collected on 7 November 2007, shows an east-west band of very green water that is in striking contrast to the otherwise clear blue Pacific. The northern edge of the bloom is sharp; the southern, more diffuse. In the sunglint contaminated portion of the scene just west of the region shown at right, the bloom splits forklike into several parallel east-west bands.

Maximum chlorophyll concentrations are significantly higher in this bloom than in the 20 September 2007 bloom. The maximum value of 117 milligrams per cubic meter that was computed for the scene at right may be contaminated by sunglint or cloud edges, but much of the band that is away from clouds and the glint field still exceeds 30 milligrams per cubic meter. (Note that the color scale for this image is different from the one on the previous page.) Again, this bloom only lasted a few days. |
One wonders if these blooms are connected to the dynamics of the tropical instability waves or if the prevailing La NiƱa conditions are a contributing factor.
