| Sep 18, 2023 at 7:38 | comment | added | NimRad | @JBH the question states temperatures ranging "below 0°c" in all regions, so the temperature range can still be quite diverse, just never going above 0°c. The reason for this is because the planet orbits its host-star shortly behind the system's frost-line. | |
| Sep 18, 2023 at 1:50 | comment | added | JBH | Are you married to the idea that the surface temperature is 0°c "at all times and in all regions"? That's a pretty tall order. Poles tend to be colder than equators. Day tends to be warmer than night. Is the planet rogue and internally heated? Or is it quite distant from its sun and, perhaps, orbiting a gas giant that causes the internal heating? Or, do you simply want us to accept the condition as true and move forward? (Although asking if something can be stable without explaining the cause of this condition makes it difficult to fully answer.) | |

| Sep 17, 2023 at 23:41 | comment | added | Neil Iyer | That makes sense. So maybe, there could be some traces, but they probably won't do as much compared to the salt and ethanol contents (which should be quite high). | |
| Sep 17, 2023 at 23:40 | comment | added | NimRad | I figure the main purpose is to keep their bodies unfrozen, so it would probably be trace-amounts. As it says in the same wiki article, it mainly helps them tolerate the cold, not directly inhibiting ice-formation. | |
| Sep 17, 2023 at 23:34 | comment | added | Neil Iyer | Do the local microbes actively spew out these anti-freeze proteins? Wikipedia says that "1 μM of Euplotes focardii consortium ice-binding protein (EfcIBP) is enough for the total inhibition of ice re-crystallization in –7.4 °C temperature" so do they use something like that, or is that not applicable here? | |
| Sep 17, 2023 at 23:25 | comment | added | Neil Iyer | Thanks for clarifying. | |
| Sep 17, 2023 at 23:25 | comment | added | NimRad | @Neil lyer it's primarily water! Only now realized that the answer didn't specify that, just edited it. | |

| Sep 17, 2023 at 23:22 | comment | added | Neil Iyer | Is your ocean primarily water mixed with these anti-freeze proteins, ethanol, and salt, or is it some different main liquid? | |
