Following up on my last question about the ecology of my skyworld here, I decided to go more in-depth and fundamental. This is going to mostly be about the behavior of the ocean and changes to the climate of the world after the ocean is introduced. Assume that the ocean is dense enough to mostly remain pooled and the tendency of gas to mix and diffuse is handwaved. My world pre-drowning would be fairly similar to Earth and have similar atmospheric circulation, average temperature, etc as Earth. This image from calculatedearth of the Earth's landmasses submerged to 1000 meters would be close to how my world looks. A few questions:
- Would the ocean change the average temperature of the planet?
- Would there be tides in the gas ocean and would they differ in nature?
- Would the climate of surviving land be altered significantly? If so, How?
- Would there be any new kinds of weather created by the event?
Albedo (black mist ocean for thematic purposes): 0.1
Albedo (alternately, a "cloud sea"): 0.75
Specific heat: 5 joule/gram °C
Edit 2: For the purposes of this question, I suppose it would be better to consider simple ground fog (the kind we have on Earth) as the gas (or aerosol, actually) that covers the land. It would probably be easier to predict the effects knowing more about the substance. My only concern is that fog doesn't seem to displace air, and the depths being anaerobic is an idea I had been considering. If the aerosol particles are suspended in a denser gas/mixture than air, would that displace the atmosphere?
