Mariana 17

Mariana 17

A mobile, submersible computing system for ocean exploration
Mariana is a mobile, submersible computer designed for Ocean Exploration. A glass sphere capable of withstanding depths of up to twelve thousand meters houses the computer, battery and electronics.

Mariana is an ideal solution for developing a low-cost, deep-water instrument platform that can easily interface with many sensors inside and outside the sphere. Its glass housing allows easy image and video recording plus wireless, optical, and GPS data connectivity without any special ports. The Mariana system includes the following key components:
