Thanks for clarifying Robert and Sergey. Working in academia these license issues rarely come up. Clearly my understanding has got a little mixed up.
I'll amend the license information on the svn.

I don't think this is required. Your own source code is yours to license how you like, it's the final composite work that would have to licensed as the GPL. For instances your headers and source could be LGPL, but when you link your application against the GPL library then resulting osgOcean library would need to be under the GPL. If FFTW was replaced by another library that was LGPL then the resulting library would be LGPL, if this library was binary binary compatible then you could actually swap the two implementations without changing anything in your code, and with it the license rules would change with it. If you make your own source code GPL, even temporarily then this isn't possible.
