ANERIS UVAS Underwater Video Acquisition System

Abstract

This report presents the process of building a low-cost, lightweight underwater observa- tory. This includes an underwater camera, hydrophone, and sensor station connected by cable to a central hub stationed on land which forwards all relevant data to designated viewers via internet. The underwater observatory is intended to be a proof-of-concept of a cheap, open-source, and easily reproducible system that has as few tool requirements as possible. This hopes to ensure that the majority of interested parties are capable of building a similar system without needing to invest sizable capital in custom part orders and/or tools. The main contributions of this project unfolds in three parts; 1. Providing power and communication to the submerged platform through a tether cable. 2. A low-cost platform to house the camera enclosure, sensors, and lights. 3. An anti-biofouling mechanism for the camera viewport to combat marine growth and reduce maintenance. The main objectives are to, at a minimum, successfully provide live audio, video, and exterior lighting that can be activated remotely, with possible additional telemetry in- cluding water temperature, pressure, pH level, salt levels and similar.
