There's no need to delete the geometry above the ocean height just to get the Grid from Bounding Box.
Instead just gen the "bounding box" of the faces that are below the ocean height.
1000x1000 Terrain and 1024x1024 Ocean Layer
The statistic node is too slow though, often times making this method slower than just deleteing, and so a better method would be best for determining the min and max.
