Explanation
The Joke
A little girl announces she wants to be a marine biologist when she grows up. Her father says he happens to know a marine biologist, and they go visit her. The marine biologist describes her daily routine: she looks at data about ocean health and then screams for a while. She shows them her "screaming room" (or "lab"), where they figure out specifically why they were screaming. They then put their findings in an envelope addressed to Congress, place that envelope in the recycling bin, and scream some more.
When the father asks why the biologist is not screaming right now, she explains she has a lab technician screaming for her next door while she talks to visitors. The father asks if this is a normal response, and the biologist says no -- it is "pure abyssal horror whistling its way out of a grown woman's larynx." In the final panel, the parents discuss Sally's career aspirations, and the father suggests that if she wants to do marine biology, he would try to find life on Enceladus instead -- implying Earth's oceans are so doomed that the only hope for marine biology is on another celestial body.
The Humor
The comic is a darkly funny commentary on the emotional toll of being an environmental scientist, particularly one who studies ocean health. The joke is that marine biologists are fully aware of the catastrophic state of the oceans -- coral bleaching, plastic pollution, overfishing, acidification -- and their rational response is perpetual screaming. The detail about writing to Congress and then recycling the letter captures the frustration of scientists whose warnings go unheeded by policymakers. The punchline about Enceladus elevates the despair to cosmic levels: rather than study Earth's dying oceans, it would be better to look for entirely new oceans on Saturn's moon.
References
Enceladus is one of Saturn's moons, known to have a subsurface ocean beneath its icy crust. NASA's Cassini spacecraft detected water vapor plumes erupting from its south pole, making it one of the most promising candidates for extraterrestrial life in our solar system. The comic references real and ongoing concerns about ocean health, including the effects of climate change, ocean acidification, and the difficulty scientists face in translating their findings into policy action.
