Anything in the ocean gets some form of life on it.  Space is limited in the ocean, and as you can see from the amount of gooseneck barnacles on the bottom of the buoy, it can get a little crowded.  Divers have to periodically clean and maintain the instruments, line and buoys from getting too weighted down from all of the algae and invertebrates that grow on them.  Here a California Coastal Data Information Program (CDIP) buoy gets some much needed love from MLML Divers Mike Fox and Paul Tompkins, while boat operator Jasmine Ruvalcaba maintains visual contact with the divers.  The CDIP buoys provide us with swell (wave) height and forecasting abilities so we know what the conditions are out on the ocean, which is very helpful when you need to do work out there!
