DATA MODEL: ACQUISITION EVENTS

1. LAUNCH (independent, navigated)• daughter platforms e.g. Submersible, Drone, Small Boat

2. LINE (navigated)• towed platforms e.g. Camera, MCS, TowYo

3. STATION (only start/stop)• lowered platforms e.g. Core, Grab, CTD, BLISP• towed platforms e.g. Dredge, Net• deployed platforms e.g. OBS, Marker, Float, Probe

Events can be nested (e.g. Dive > Station)
