Accompanied by her two friends, Cindy and Noah, Shelby pursues various detective adventures. In the premiere episode, she learns how to SCUBA dive but becomes trapped in a boat while gathering clues to solve the mystery of a stolen coin...
...down on the snow and await the next hour's replacement? We would be a layer of snow, part of the landscape, and the dogs could frolic among us, within the snow. Our vision would be crysalline and white, as if we were under the sea though specifically not scuba diving. If we were under the sea, we would be constructing a reef, not building it with our hands but supplying it with our bodies as building material. We would be the snow reef and the snow reef would be us. A living, unified organism within the snow. Bobcats...
...Even today, the cluster of islands, a province of Ecuador that lies some 600 miles off the South American coast, seems idyllic: the giant tortoises known as galapagos, which gave the islands their name, still amble across the scrubby landscape, sea-lion pups and Galapagos penguins gaze unafraid at scuba divers, marine iguanas crawl over volcanic rocks along the shore, and strolling tourists have to detour around blue-footed boobies (a type of seabird) busily performing courtship rituals. Puerto Ayora, the islands' largest town (pop. 8,000), comprises a tranquil collection of quaint hotels, craft shops and seafood restaurants...
...these reasons the modern age of deep-sea exploration had to wait for two key technological developments: engineer Otis Barton's 1930 invention of the bathysphere--essentially a deep-diving tethered steel ball--and the invention of scuba (short for "self-contained underwater breathing apparatus") by Jacques-Yves Cousteau and Emile Gagnan in 1943. Swimmers had been trying to figure out how to get oxygen underwater for thousands of years. Sponge divers in ancient Greece breathed from air-filled kettles; bulky-helmeted diving suits linked by hose to the surface first appeared in the 1800s. But it wasn't until...
Even the most experienced scuba divers rarely venture below 150 ft., however, owing to increasingly crushing pressure and the laborious decompression process required to purge the blood of nitrogen (which can form bubbles as a diver returns to the surface and cause the excruciating and sometimes fatal condition known as the bends). And pressurized diving suits make it possible for humans to descend only to 1,440 ft.--far short of the deepest reaches of the oceans...
