Perhaps you’ve seen those spherical yellow buoys bobbing on the ocean off San Diego’s coast. Have you ever wondered what’s inside them?
Well, there’s a CDIP (Coastal Data Information Program) buoy on display near the Birch Aquarium at Scripps Institution of Oceanography. And a nearby sign describes the technology that makes a buoy such a valuable resource of information!

Buoys like this one measure wave height, period, direction and sea surface temperature information.
The data is used by coastal engineers, planners, scientists, harbor masters, lifeguards, mariners, boaters, surfers, divers, fishers and beach-goers! That’s a lot of people who benefit from buoys!

Inside a plain-looking buoy there are various high tech instruments, including accelerometers, magnetometers, a thermometer, acoustic pingers, a computer, GPS and antenna to transmit all the collected, archived information!
(Did you know biofoul was a word? I didn’t!)
Next time I see one of these yellow CDIP buoys, I’ll have a much greater appreciation of what they are!
