The Real Big Blue

Sometimes you have to get into the remote environment where marine organisms live to study them: WHOI biologists Larry Madin and Richard Harbison were part of a small group in the United States that pioneered blue-water scuba diving in the 1970s to observe jellyfish and other soft transparent creatures in their natural habitat—the open ocean. Divers used a tether system, with a designated "safety diver," so that they could concentrate on observing transparent organisms and avoid drifting away from the team and becoming lost in the vast blue world.
