Sealab

Sealab is a fictional underwater research facility featured in the 1970s television series of the same name. The series, created by Irwin Allen, aired from 1971 to 1974 and was a spin-off of the earlier series Lost in Space. Sealab 2020, the primary setting of the series, is an underwater research station located off the coast of California. The station is designed to study the effects of living and working in an underwater environment, as well as to conduct various scientific experiments.

The series follows the adventures of the Sealab 2020 crew, which includes Dr. Steve Austin, the station's director; Dr. Lisa Nelson, a marine biologist; Dr. Ben Brown, a geologist; and Dr. Helen Mahoney, a chemist. The crew faces various challenges and dangers while conducting their research, including underwater earthquakes, alien encounters, and other scientific mysteries.

Sealab is notable for its groundbreaking special effects, which included the use of a large underwater set and a variety of underwater vehicles. The series also featured a number of guest stars, including future stars such as Farrah Fawcett and Bruce Dern. Despite its initial success, Sealab was canceled after three seasons due to declining ratings and high production costs. The series has since gained a cult following and is often cited as an example of 1970s science fiction television.
