|Earth Pre-Federation Database - Cetacean Institute|
|Aquarium and marinebiology research facility located in Sausalito on Earth in the 20th century. Kirk and Spock, traveling back in time,
visited the Cetacean Institute to find two humpback whales in hopes or repopulating that species in Earth's 23rd century.
Star Trek IV: The Voyage Home
The Cetacean Institute scenes in Star Trek IV were filmed at the Monterey Bay Aquarium, which looks a lot like the Cetacean Institute except that it doesn't have a big whale tank (which was added with a bit of visual effects magic by ILM). The name had to be changed to the Cetacean Institute because it was necessary, for plot reasons, to move the location of the aquarium to Sausalito. The Cetacean Institute symbol is actually the logo of the Monterey Bay Aquarium, even thought the name was changed to protect the innocent.
