seaQuest DSV - Season 1

In the year 2018, mankind is colonizing the oceans and exploiting their resources, establishing small undersea farming, mining, and manufacturing communities. But with the newfound potential comes old-fashioned conflict and the United Earth Oceans Organization (U.E.O.) assigns the submarine, seaQuest, DSV, led by Captain Nathan Bridger to keep the underwater peace and generally patrol the planet's final frontier. Amongst the crew is a teenage genius, Lucas Wolenczak, and Darwin, the intelligent dolphin, who thanks to Lucas's inventions can understand human speech and whose speech can be translated in to English.
