NSF Development Development funded by NSF The Surface Piercing Profiler is Ultimately a Vendor Supplied System The SeaCycler is an exemplar for the Global OOI Surface Piercing Profiler
- Used on a sub-surface mooring. -Profiles (or moves) instruments from a 150m depth, to the surface and back collecting data - When at the surface, it floats a small satellite antenna to communicate data to shore and receive new commands - No surface expression, except when communicating - Conserves power to enable numerous long profiles - Designed for the open-ocean. 150m
Mechanism Float (underwater winch) Instrument Float - travels 150m to Surface 23m fixed cable length Communication Float - travels with the InstFloat Flotation Sphere Profiling Principle A small buoyancy moved a long distance is balanced by a large buoyancy moved a short distance in the opposite direction.
-Satellite communication for near real-time data and remote control operation -Inductive modem coupling to deeper-water instrumentation -Open-ocean design suitable for deep water (5000m) sites -Profiling -365 x 150m profiles are possible for year-long deployments -Profile stops for discreet sampling -Extra cable storage to compensate for mooring knockover -150m hide-depth for security and bio-fouling -Surface wave detection -Large instrument payload (100 lbs in air) -Simple straight-through cable routing – anchor to surface SeaCycler Capabilities
