D Profiler

Autonomous Vertical Profiler

Autonomous Vertical Profiling of the Water Column

D Profiler from Dartmouth Ocean Technologies (DOT) enhances water column surveys by collecting multiple sensor readings at a location defined by the user’s Unmanned Surface Vessel (USV) or Unmanned Underwater Vehicle (UUV). The D Profiler is a vertically profiling buoy with an adaptable and modular sensor capability that can transmit data via a variety of data channels – UHF radio and mobile phone.
