Persistent Undersea Presence

  1. 1. PERSISTENT UNDERSEA PRESENCE THROUGHOUT THE OCEAN Expanding the reach of ocean science, industry and defense.
  2. 2. Unmanned maritime vehicles (UMVs) are becoming common in marine applications. Two unmanned systems providing cost- effective access to the global ocean are gliders and floats. Gliders are now well known, with hundreds employed by users around the world. Profiling floats number in the thousands and are an integral component of ocean observation strategies. PERSISTENT UNDERSEA PRESENCE THROUGHOUT THE OCEAN But there are some limitations. Drifting floats typically do not reach below 2,000 m deep, leaving a large fraction of the global ocean out of reach.
  3. 3. Recent Teledyne Marine Systems developments in profiling floats are changing this. Earlier this year a drifting float demonstrated the ability to dive to 6,000 meters depth. Capitalizing on cost effective glass spheres for pressure housings and building on core expertise in buoyancy engines, this new tool expands the reach of drifting profilers to 97% of the ocean.
  4. 4. Together these innovations are While the ocean will remain a hostile environment, the information required to observe and understand that environment is becoming ever more available. Teledyne is innovating at the intersection of propeller driven AUVs and gliders. New hybrid gliders offer a small folding blade thruster to augment their buoyancy drive. This enables flight beyond the traditional up/down cycle and access to regions, such as those with strong water density stratification or strong current regimes, previously inaccessible. With the option to retrofit older systems or install on new builds, this innovation dramatically widens the performance envelope of an already cost-effective tool for ocean observation.
