Welcome to the sub-eye page of the Fish Ecology Group at IMEDEA and LIMIA. Here we present the activity of our cabled seafloor observatory located at LIMIA’s facilities, Port d’Andratx. Enjoy!

Description

The Port d’Andratx underwater cabled observatory is a multi-port underwater system that can handle four Ip underwater cameras at a time. It is connected to a land-based station through a voltage cable and fiber optic link to carry digital data. It currently holds two Ip cameras and has an independent temperature and sea-level gauge at the land-base serving real-time data.

Objectives

The objectives of the system are threefold. Firstly, it aims at providing continuous image files (saved each 15 minutes) that enable the long-term time-series analysis of image-based data. The camera used for this purpose is currently focusing an underwater vessel that attracts biomass in a highly anthropized environment. The Fish Ecology group at IMEDEA develops image-based solutions for estimating ecological parameters of key species within several projects (see the corresponding section in our web). Secondly, it is the objective of the sub-eye to serve as a communication and diffusion tool, through enabling access to real-time video (under construction). Lastly, it aims at constituting an underwater node to record potential changes in species/communities that can be part of a broader community of underwater nodes.

Fundings

This observatory has been partially financed by the research projects REC2 (CTM2011-23835) and PHENOFISH (CTM2015-69126-C2-1-R) from the Spanish Ministry of Economy and Competitiveness (MINECO).
