Cutting out piece of geo with curve

[anbt]

Hello guys, I feel this has been asked probably a thousand times, but I can't really find a simple answer.
I have projected this curve onto this surface with a Ray sop.
I basically want to divide my geometry into two islands with this curve and delete the bottom part.
Any ideas?

Thanks a lot

Thanks Librarian, I did check those threads out but they were quite old and using lots of nodes to do something I thought would require not more than 2 nodes now!
Anyway, I did it that way at the end.

Cheers

I wanted to try with the Project SOP but it requires Nurbs surfaces. I converted my half sphere into Nurbs surface but the problem is that I end up with as many Nurbs surfaces as there are primitives. To make the convert SOP works, I should only have one apparently.
How can I convert all the surfaces into just 1? I tried with the Join SOP, no success.

Any ideas?
Cheers

@anbt Oldyyy Nostalgia
  and some link to _______ if you gonna use Sphere only on and for modeling .This dude posted long  time Ago File(Nice Tricks) and if you combine Pretty much you can make(model) anything easily I think.
