Getting the Kerbin/Water/Landed surface sample legitimately?

[mattihase]

The game has science reports allocated for being "Landed" on kerbin's water, which seem to indicate that they expect the player to be underwater when performing these experiments. at the moment you can get them all at the end of the runway because of some interesting biome map painting so that's handy, however assuming that eventually gets fixed, is there a legitimate way to get a kerbonaut to walk around underwater without floating to the surface for long enough to take a sample?

My guess is diving bell on the bottom of the sea. Perhaps exiting it while holding on to the hatch? Yes an capsule who sink might work just as well the diving bell is for aquatic science.

I thought you couldn't perform experiments while on a ladder.

You are correct for landings, not even standing on an tank or wing let you take ground samples who makes sense. But underwater might change stuff. 
Some who tested this tell.

IIRC you can still plant flags when standing on a tank if you want to plant sky flags.
