Submersible Technologies
The submersible Perry Cubmarine aboard Sea Diver
S.D.C. in the water
Link continued inventing new types of diving and submersible equipment that would allow divers to both stay underwater longer, and reach deeper depths of the ocean. He continued to nurture partnerships with the Smithsonian, the United States Navy, and other research groups that were interested in the new horizons Link envisioned for the future of underwater exploration.
Some of Link's inventions include submersible decompression chambers, or SDCs; a Submersible-Portable-Inflatable Dwelling (SPID), underwater workspaces like the IGLOO, and early iterations of other submersibles, like the Perry Cubmarine. Some of of Ed Link's inventions served a very special purpose: one machine, CORD, was built after the death of his son Clayton. You can read more about CORD and Clayton's story on the next page.
