ocean science, industry and defense.

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.

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. 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. 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.
