The Jovian Environment I

"...that monstrous atmospheric ocean..."
-Poul Anderson, Three Worlds To Conquer (London, 1966), Chapter 3, p. 21.

This means either literally that the Jovian atmosphere combines gaseous and liquid properties so that it could equally be described as a monstrous oceanic atmosphere or metaphorically that the atmospheric gases are dense and turbulent like the waves of an ocean. The gases are:

"...mostly hydrogen, much helium, a few percentage points of methane, ammonia vapor, and other gases..." (ibid.)

The mantis-like "forgar" is said to fly - or swim. (p. 23)

There are mile-high red cloud banks with tawny precipices. Sun and moons cannot be seen from the surface but dawn is perceived as a swiftly climbing brightness. Human eyes would see only by "...the frequent great lightning flashes..." (p. 21) but Jovians see in the infrared.

Soil is ice powder intermingled with sodium and ammonium compounds. The real ocean is "...thousands of storm-swept miles of liquid ammonia..." (p. 22)

Much more later.

Kaor, Paul!

I think "monstrous" in this context means that for humans Jupiter and its environment is huge, vast, violently turbulent, etc.
