Berglund About 20 miles south of Cancun, Mexico, on a stifling summer day, Tom Iliffe squints over a limestone ledge and into a giant pool of scuzzy, brown water. A spool of bright-orange nylon line and an assortment of mesh bags carrying glass test tubes, plastic caps and measuring devices dangle at his side. Below, the water temperature is roughly the same as the air.
PREVIOUS NEXT Edgerton was much in demand from the s to the s for underwater exploratory and archaeological expeditions as an expert in underwater photographic techniques and, later, in the use of side-scan sonar devices for discovering objects and geological information on and beneath lake beds and ocean floors.
Inthe National Geographic Society asked Edgerton to join them in underwater exploration, and Doc meet the leader of the expeditions, Jacques-Yves Cousteau who became a life-long friend. Cousteau co-developed the aqua-lung, and pioneered marine conservation.
Edgerton started building underwater flashes and cameras for Cousteau, but soon realized the murky ocean waters would require some kind of sound system to augment his cameras. Echoes returning from the pinger indicated how close the camera was to the bottom. He used the boomer to find an H-bomb off the coast of Spain, search for the ancient Greek city of Helice submerged about B.
InEdgerton and colleagues designed an elapsed-time photographic system that could take motion pictures of underwater events, using strobe lights for illumination.
This system made it possible to photograph the movements of sand dollars, sea urchins, and other marine creatures whose movements are normally too slow to humans to see.In , the National Geographic Society asked Edgerton to join them in underwater exploration, and Doc meet the leader of the expeditions, Jacques-Yves Cousteau who became a life-long friend.

With safety being paramount, operators assure underwater habitats are running smoothly by monitoring life support systems – air composition, temperature and humidity – from the surface.
The Scorkl offers new worlds of exploration. Instead of holding your breath for 15 to 20 seconds for each exploratory venture underwater as you would do without assistance, the Scorkl expands your. Undersea exploration: Undersea exploration, the investigation and description of the ocean waters and the seafloor and of the Earth beneath.
Included in the scope of undersea exploration are the physical and chemical properties of seawater, all manner of life in the sea, and the geological and geophysical features of. Underwater Life & Exploration. Take a deep dive into ocean life as it’s never been seen before by following National Geographic experts through unchartered waters and explore the abundance of amazing discoveries that have come from our seas.
