This paper presents the design and implementation of a ROV-based acquisition system designed for water quality monitoring through the acquisition of oceanographic parameters of Peruvian water resources such as rivers, lakes and oceans. The robotic platform integrates a video camera, a multi-parameter probe for water quality analysis and an array of three hydrophones in order to measure underwater noise. The versatility of an underwater vehicle is exploited by centralizing data acquisition and logging in a sole flexible platform. The presented prototype is developed to be used as a research platform and as a measurement tool for the Peruvian Institute of the Sea (IMARPE-Instituto del Mar del Perú) in order to extend its capabilities on oceanographic parameters monitoring. Preliminary results of the ROV hydrophones and multi-parameter probe are presented and discussed in this work.
