"This is the year two thousand and twenty. The place is the Challenger seamount, the top of an underwater mountain, a complex beneath the sea. 250 men, women and children live here, each of them a scientist-pioneer. For this is our last frontier, a hostile environment which may hold the key to tomorrow. Each day these oceanauts meet new challenges, as they build their city beneath the sea. This is Sealab 2020."A short lived Hanna-Barbera cartoon, airing in 1972. The show followed the exploits of the crew of Sealab, an underwater research station devoted to studying, exploring, and protecting underwater marine life. The show had a short run, with only 13 episodes aired (and three left unfinished).The show wasn't well remembered except for occasional early morning repeats on Cartoon Network, before the burgeoning program block [adult swim] parodied it as Sealab 2021.
Tropes featured in this show:
- All Animals Are Dogs: As Hal said, "basking sharks are like the puppies of the ocean."
- Atlantis Is Boring: This is said to one of the main problems of the series.
- To people who did watch the show, the core cast is sometimes criticized as not being as interesting as they could have been.
- Color-Coded Characters: As listed below the wet suit the characters wear are color coded by position.
- Distressed Damsel / Distressed Dude: Bobby and Salli need to be rescued in the pilot
- Driven to Madness: Due to green fever, a minor character tries to sabotage Sealab
- Family-Unfriendly Violence: One episode deals with a hunter tracking and trying to kill a whale.
- Green Aesop: More often than not.
- Heel–Face Turn: Several examples to put over the Green Aesop.
- It Was Here, I Swear!: Nobody at first believes Gail when she sees the giant squid.
- Limited Animation: Like most cartoons of its era.
- Limited Wardrobe: Since the show takes place in an undersea base, it's sort of a Justified Trope. Every one wears a diving suit (orange for scientist, blue for other job, yellow for student)
- Slightly subverted when each characters get a helmet when they go diving.
- No Name Given: A good chunk of the other workers in Sealab.
- Rising Water, Rising Tension: In "Green Fever", a red alert is signaled after a supply ship's concrete mooring, cast off during a hurricane, unwittingly strikes Sealab's control dome and splits a major section of the shell, causing it to start flooding.
- Underwater Base/Underwater City: Sealab, of course.
- What Happened to the Mouse?: There are clearly lots of workers in Sealab but outside of the primary cast most only get shown in one episode to never be mentioned again.
