Getting it safely on and off the ship takes two cranes, about eight people and a lot of shouting from the bosun. But when it's floating out in a storm, it looks very small. Anyone can see the foam patches left on the surface by breaking waves, but this buoy lets us see what's hidden just underneath. Breaking waves will leave behind bubble plumes that could be many metres in size, and each bubble has the potential to transport a tiny puff of gas up or down. It still astonishes me that such minuscule things can make a contribution to how our planet works. But there are billions of them, and they do. |
