Abstract
An untethered device includes a housing, a chamber wall extending from the housing and defining a buoyancy chamber, and a discharge door. The discharge door is configured to be placed in a closed position that isolates a ballast weight within the buoyancy chamber and an open position that allows a release of the ballast weight from the untethered device to reduce a bulk density of the untethered device.
