Today it is an economic and even geopolitical necessity for oil companies, in order to maintain pipelines and offshore rigs, to send divers routinely to depths of a thousand feet, and keep them at that level of compression for as long as a month at a time. The divers who do this work are almost entirely male, and tend to be between the ages of twenty-five and forty. Were they any younger, they would not have enough experience or seniority to perform such demanding tasks. Any older, and their bodies could not be trusted to withstand the trauma. The term for these extended-length descents is “saturation diving,” which refers to the fact that the diver’s tissues have absorbed the maximum amount of inert gas possible.
