 Well known in aviation  
 circles, Link had invented  
 the pioneering Link Trainer,  
 an early flight simulator that  
 helped train more than 10,000  
 pilots during World War II. Link  
 had since turned his attention  
 to ocean exploration and immediately  
 began building the  
 submersible Johnson-Sea-Link I at  
 Harbor Branch in 1971. 
 SUBMERSIBLES SUCCESS 
 The Johnson-Sea-Link I and  
 its successor Johnson-Sea-Link  
 II in 1975 were revolutionary  
 in having a 2-meter diameter  
 acrylic clear sphere that allowed  
 scientists an almost 360-degree view of the ocean, to a depth  
 of 900 feet. The craft had lockout capabilities, allowing divers  
 to exit and re-enter the sub at depth. 
 At the time, Harbor Branch was one of only three centers  
 in the United States and one of only six similar worldwide  
 organizations using submersibles for scientific discovery. 
 For the next three decades, the JSLs made more than 9,000  
 dives worldwide, allowing researchers to unlock many mysteries  
 of the deep ocean.  
 The submersibles were key to the discovery of previously  
 unknown deep-sea coral reefs only a few miles north of Fort  
 Pierce by Harbor Branch researcher John Reed. 
 Reed, 73, is the longest-employed scientist at Harbor  
 Branch. He started there straight out of graduate school in  
 1976, when it was just beginning to use the submersibles as  
 useful scientific tools. 
 He recalls the staff at Harbor Branch as a small tight-knit  
 group of young researchers, engineers and operational staff  
 who worked and played hard together. 
 It was the submersibles that really put the institute on the  
 map, Reed believes.  
 “People saw them on TV and the national news and immediately  
 associated them with us,” he says. 
 CORAL REEF FOUND 
 At first, Reed was involved in aquaculture research, but  
 because he had free access to the submersibles, he was able to  
 switch his area of interest. Reed discovered the Oculina Reef  
 in 300 feet of water off the Treasure Coast. It was a pristine  
 world of fantastic coral formations and thousands of fish.  
 One soccer ball-sized head of coral could support up to 2,000

 The FAU Harbor Branch  
 campus has undergone  
 major changes during its  
 half-century lifespan. 
 John Reed is the longest-employed  
 researcher at Harbor Branch. He  
 has worked on deep-sea reefs and  
 their protection since arriving in  
 Fort Pierce in 1976. 
 The Oculina Bank, previously unknown deep-sea coral reefs only a few  
 miles north of Fort Pierce, was discovered by Reed in 1984.
