Re: [PSUBS-MAILIST] Re: Welcome to the Personal_Submersibles_Disc ussion
A slightly squashed sphere> ie rounded top, rounded bottom, with very
slightly (depending on depth, getting more drastic as one increases the
size of the bubble and as it approaches the surface) tapering from a
smaller radius at bottome to larger at top.
ie an ellipse with varying minor axis?
My Guiess,
Jay.

I would say an inverted cone (the base up and the point down)???
