Hello!

Does anyone know if there is some sort of documentation describing underwater pictures processing with The Gimp?
I recently bought an underwater digital, camera but the pictures are too green. Any tips or suggestions?

This isn't specific to underwater pictures, but you could try - Opening the picture you want,
Right clicking the image and following the menu down through layers->colours->curves,
Selecting the green channel in the drop box on top, And adjusting the curve so the picture looks like you want it to.

Well, part of tweaking underwater pictures is knowing why they look the way they do. Water absorbs the reds and to a lesser extent, orange, while passing the complement, blue-green. Depending on the distance from the white light source (sky/strobe) you might want to either try increasing red levels or turning down the blue/green components. http://www.scubaboard.com/cms/article18.html
