Aircraft Powered airborne platform Array A complex platform type that is characterized by a suite of instruments/devices that are designed to operate as a unit. Arrays can be towed or deployed on the seafloor. An example is a multi-channel seismic array. ASV Autonomous Surface Vehicle AUV Autonomous Underwater Vehicle such as ABE Boat A watercraft of modest size (smaller than a ship) that operates at the water surface. Cabled Observatory Infrastructure that enables live access to instruments on the seafloor via cabled connection. CORK Circulation Obviation Retrofit Kit. A sealed subseafloor Borehole Observatory CTD CTD cage to which other instruments can be attached Elevator A platform that is used to transport samples or equipment from the seafloor to the surface and vice versa. Float A platform that is carried passively by ocean currents Float:Profiling A free-moving platform that is equipped with sensors and records vertical profiles of water properties at regular time intervals. Glider A type of autonomous underwater vehicle that uses small changes in its buoyancy in order to move up and down like a profiling float. HOV Human-Occupied Vehicles are submersibles that carry personnel. Alvin is an example. HROV A Hybrid Remote Operated Vehicle (HROV) is a submersible that can be operated in two different modes, either as a Remote Operated Vehicle (ROV) or an Autonomous Underwater Vehicle (AUV) Mooring An instrument platform typically attached to the seafloor NotApplicable Platform type either does not apply or cannot be known NotProvided Platform type was not provided but can be known ROV Remotely Operated Vehicles are tethered to their mother platform (typically a ship) from which the vehicle is operated. ROVs do not carry personnel. An example is Jason II. Satellite Space-borne instrument platform Seismic:MCS Used primarily for entry_event_line_set Multi-Channel Seismics Seismic:SCS Used primarily for entry_event_line_set Single-Channel Seismics Ship A large watercraft that operates at the water surface. Sled A frame on which devices are mounted. It is connected to a mother platform by a wire. It is without autonomous propulsion. Examples are WHOI TowCam, and WHOI DSL-120 platforms. Thermosalinograph Instrument that measures sea surface temperature and salinity using a water intake system Tripod A three-legged platform that can be equipped with a variety of devices. USV Uncrewed Surface Vessel (USV) WeatherStation Collects multiple types of weather-related data
