Recently, biofouling on the ports began ot cut off the field of view, showig that it was time for another cleaning. Scripps divers were able to clean off the ports, as well as replace a cable that had ceased to function. Thanks to their hard work, the SPC is once again capturing and saving live data. How does a cable break happen? Generally it starts with a small hole in the jacket from a barnacle. All it takes is a smal gap for seawater to access one of the conductors in the cable. In this case, it was the ground line that got exposed. Once open to the water, galvanic corrosion sped along by the operating voltage then make short work of the exposed conductor.
