Newly reported research suggests Enceladus' ocean isn't relatively uniform and static, but rather dynamic with global currents.
Encased in an Icy Shell, the Ocean on Saturn’s Moon Enceladus Appears to Be Churning

Buried beneath 20 kilometers of ice, the subsurface ocean of Enceladus—one of Saturn’s moons—appears to be churning with currents akin to those on Earth.

The theory, derived from the shape of Enceladus’s ice shell, challenges the current thinking that the moon’s global ocean is homogenous, apart from some vertical mixing driven by the warmth of the moon’s core. ...

The ocean on Enceladus is almost entirely unlike Earth’s. Earth’s ocean is relatively shallow (an average of 3.6 km deep), covers three-quarters of the planet’s surface, is warmer at the top from the sun’s rays and colder in the depths near the seafloor, and has currents that are affected by wind; Enceladus, meanwhile, appears to have a globe-spanning and completely subsurface ocean that is at least 30 km deep and is cooled at the top near the ice shell and warmed at the bottom by heat from the moon’s core. ...

Despite their differences, Caltech graduate student Ana Lobo ... suggests that oceans on Enceladus have currents akin to those on Earth. The work builds on measurements by Cassini as well as the research of Andrew Thompson, professor of environmental science and engineering, who has been studying the way that ice and water interact to drive ocean mixing around Antarctica. ...

Its got a ginormous geyser.

Scientists caught Saturn's icy moon Enceladus spraying a "huge plume" of watery vapor far into space — and that plume likely contains many of the chemical ingredients for life.

Scientists detailed the eruption — glimpsed by the James Webb Space Telescope (JWST) in November 2022 — at a conference at the Space Telescope Science Institute in Baltimore on May 17.

"It's immense," Sara Faggi, a planetary astronomer at NASA's Goddard Space Flight Center, said at the conference, according to Nature.com. According to Faggi, a full research paper on the massive plume is pending. ...

Life on Enceladus?

SAN FRANCISCO — For those delighted by the possibility of alien life, Enceladus, the wintry moon of Saturn, is a gift that just keeps giving.

Key compounds that could support alien microbes or help life emerge have been detected in the enormous plume of water that erupts from vents in Enceladus’ icy shell, biophysicist Jonah Peter of Harvard University reported December 15 at the American Geophysical Union annual meeting. These include hydrogen cyanide, which can be toxic to humans, though Peter noted it’s also “a key building block for synthesizing more complex compounds including amino acids, sugars and nucleobases, which in turn are precursors for proteins, RNA and DNA.” ...
