Hadal Profiler

Hadal Water Column Profiler

A project I'm working on is the Hadal Water Column Profiler. The profiler is designed to free-fall to the seabed and return autonomously. Key design requirements include getting as close to the seabed as possible without hitting it, and be able to operate at hadal depth (~11 km at the deepest part of the ocean).

The profiler carries various scientific instruments that measure parameters for physical oceanography and marine biology. It is also capable of bringing up water samples at programmed depths.

The scientific instruments and vehicle hardware come from various university groups and commercial vendors in the USA, Canada, and Australia, some experimental while other commercial-off-the-shelf. My job is to handle the electrical and software system integration, and to develop system-level components such as the autonomous control logic, validation and tests, and user interface, to name a few.
