Scuba gear

Breathe air of normal composition, but at a greater overall pressure. An example of this approach is the diver who breathes underwater while fitted out with SCUBA gear. 

In a similar study, Levesque et al. (1994) attempted to quantitate the body burden of chloroform following exposure in an indoor pool. Scuba divers were exposed to chloroform-laden water and air on each of seven days. On each exposure day, the subjects exercised for a 55-minute period alveolar air samples were collected before exercise and after 35 or 55 minutes of exercise. Pre-exercise alveolar levels of chloroform averaged 52.6 ppb this was attributed to air contamination in the locker room. Alveolar air concentrations of chloroform after 35 and 55 minutes of exercise increased steadily through day 5, averaging 100-950 and 104-1,093 ppb, respectively. On day 6, when scuba gear was worn by the subjects, alveolar air concentrations after 35 and 55 minutes of exercise were 196 and 209 ppb, respectively. The authors concluded from this data that the average proportion of body burden due to inhalation after 35 and 55 minutes exercise was 76 and 78%, respectively. 

The ocean conceals a vast number of unexplored, and potentially valuable, archaeological sites. But the technology needed to explore these sites was not perfected until the mid-twentieth century. With the development of scuba gear, underwater transport, and other underwater devices, archaeologists have improved their ability to survey and retrieve objects underwater.

Coolness Uncool. The crocodile submarine in Octopussy has many more applications. In fact, so does simple scuba gear. Q Branch was apparently hitting the NyQuil when they thought this one up. 

Those of us born in the Forties grew up on photos of eminent scientists setting off on expeditions, their sunburnt faces dwarfed by mountain explorer s garb, or making thumbs-up signs as they entered the water in scuba gear. We shared their confident expectation that the Loch Ness Monster, Sasquatch, the Yeti - even a dinosaur-soon would be taken alive (.) As a kid, I passionately wanted to be (...)...
