Hi Laura,

The problem you've encountered pertains to the fact that the FLAASH 
module (a front-end to MODTRAN) will work adequately over bright 
(terrestrial) targets, but is poorly poised for dark (marine) ones. 
You should expect better results by using an alternative model, such 
as Tafkaa. Keep in mind though that Tafkaa is a hyperspectral 
atmospheric correction algorithm and will need to be massaged to work 
with the broad bandsets of QB and WV-2.

Good luck with it.
