A Dense Atmosphere is a type of atmosphere known for possessing a very high pressure, but is still breathable without assistance.
- However, many sophonts accustomed to standard atmospheres may breath with considerably more difficulty.
Description (Specifications)
An atmosphere rated as Dense has a mean surface pressure ranging from 1.50 atm to 2.49 atm.
| Surface pressure |
boiling point of water |
| 1.5 atm | 111°C |
| 2 atm | 120°C |
| 2.5 atm | 127°C |
Dense, High (D): These worlds have thick N2/O2 atmospheres, but their mean surface pressure is too high to support unprotected human life (high pressure nitrogen and oxygen are deadly to humans). However, pressure naturally decreases with increasing altitude, so if there are highlands at the right altitude the pressure may drop enough to support human life. Alternatively, there may not be any topography high enough for humans to inhabit, necessitating floating gravitic or dirigible habitats or sealed habitats on the surface. [1]
