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).
Tropes featured in this show:
- All Animals Are Dogs: As Hal said, "basking sharks are like the puppies of the ocean."
- 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.
- HeelFace Turn: Several examples to put over the Green Aesop.
- Hollywood Science: Mostly averted, in a lot of the plots stay fairly accurate.
- It Was Here, I Swear!: Nobody at first believes Gail when she sees the giant squid.
- Know When to Fold 'Em: In "Collision of the Aquarius", while the Sealab crew plan to cut their way into the eponymous submarine's nuclear reactor room from the bottom, the sub's captain, Glenn, tries to break into the reactor himself through the hatch, doubting that Sealab would make it in time. Captain Murphy knows that this is dangerous, since there is a possibility that the reactor's automatic carbon control system won't work, resulting in Glenn attempting to insert the carbon rods by hand without shielding, meaning he would risk radiation poisoning. Glenn only gives up on his folly when he sees Sealab successfully able to get into the reactor room first.
- The Leader: This trope actually takes a realistic approach to this trope. Dr. Paul Williams is the head scientist of Sealab and if often the one to lead the science decisions. Captain Murphy is the head of security, when there is trouble in Sealab Murphy takes charge of that part of the operation. Williams and Murphy throughout the series regularly ask for one another's advice for issues as one would in real life mission.
- 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.
