Incident at OBSEA
16/12/2014 - Sunday, November 16 at 22:00h, a fishing net was caught in the observatory and broke the underwater lighting system. During this week we will make maintenance in order to remove the fishing net and to repair the lighting system.
New Camera in the OBSEA
17/11/2014 - We have installed a second camera in the OBSEA observatory!!
The camera has a brush that is activated periodically to clean the glass. We have also mounted two lasers placed in parallel and spaced at known distance that helps to determine size the fishes.
OBSEA is a cabled seafloor observatory located 4 km off the Vilanova i la Geltru coast in a fishing protected area. It is connected to the coast by an energy and communications mixed cable.
The main advantages of having a cabled observatory are that it provides an uninterrupted power supply to the scientific instruments and offers a high bandwidth communication link. This way, real time data is available and problems encountered in battery powered systems are avoided. The proposed solution is the implementation of an optical Ethernet network that transmits data continuously to marine sensors connected to the observatory. With OBSEA, we can perform a real time observation of multiple parameters in the marine medium.
