Deployment day for the Offshore Surface Mooring (OSSM). The Multi-Function Node (MFN) sits on the fantail of the R/V Neil Armstrong awaiting final testing. The acoustically-triggered release (yellow case) is connected to the ship’s winch wire and will be disconnected when the MFN reaches deployment depth.
