Hi Geoff,

Making the mass of a seismometer neutrally buoyant will get you nowhere.
The mass will not differentially move with respect to the frame when
external acceleration is applied. You may be able to demonstrate a long
period, but you will get no signal.

Hello Mr. Nordgren,



You speak in a way I might be able to understand.



What I was wondering is that buoyancy can be implemented in ways

which might produce spring like results possibly one might

use a "weak spring (low weight/inches)" with whatever mass

in combination with buoyancy "like a submarine or ship" to

produce extended or lower frequencies using shorter lengths.

simply submerging the mass within a dense liquid may allow

this to happen.



has such a thing ever been tried ?



I saw this research ship which could be flooded

to float like a fising bobber ? it made me think

of other things like this one above.



thanks for your responses.



regards,
