Active formation of ‘chaos terrain’ over shallow subsurface water on Europa

  author={Britney Elyce Schmidt and Donald D. Blankenship and G. Wesley Patterson and Paul M. Schenk},
Europa, the innermost icy satellite of Jupiter, has a tortured young surface and sustains a liquid water ocean below an ice shell of highly debated thickness. Quasi-circular areas of ice disruption called chaos terrains are unique to Europa, and both their formation and the ice-shell thickness depend on Europa's thermal state. No model so far has been able to explain why features such as Conamara Chaos stand above surrounding terrain and contain matrix domes. Melt-through of a thin (few…

Formation of ridges on Europa above crystallizing water bodies inside the ice shell
Abstract Jupiter’s second Galilean satellite, Europa, is a Moon-sized body with an icy shell and global ocean approximately 100 km thick surrounding a rocky interior. Its surface displays extensive
Ice melting and downward transport of meltwater by two-phase flow in Europa's ice shell
With its young surface, very few impact craters, and the abundance of tectonic and cryovolcanic features, Europa has likely been subjected to relatively recent endogenic activity. Morphological
Ice collapse over trapped water bodies on Enceladus and Europa
Icy satellite surfaces are riddled with geological indicators that can inform what lies beneath. Here we investigate effects of trapped or perched subsurface liquid water on the surface above. We use
Water generation and transport below Europa's strike‐slip faults
Jupiter's moon Europa has a very young surface with the abundance of unique terrains that indicate recent endogenic activity. Morphological models as well as spectral observations suggest that it
Timing of chaotic terrain formation in Argadnel Regio, Europa, and implications for geological history
Abstract Chaos terrains are among the most prominent landforms of Europa, and are generally among the youngest features recorded on the surface. Chaos units were formed by to endogenic activity,
Domes, pits, and small chaos on Europa produced by water sills
Pits, domes, and small chaos on Europa's surface are quasi-circular features a few to a few tens of kilometers in diameter. We examine if injection of water sills into Europa's ice shell and their
Can Earth-like plate tectonics occur in ocean world ice shells?
Abstract The outer H2O ice shell of Europa, a Galilean satellite of Jupiter thought to exhibit a global interior water ocean, shows evidence for plate-like surface motions along tectonic boundaries.
Dynamic Europa ocean shows transient Taylor columns and convection driven by ice melting and salinity
The meridional oceanic heat transport is intense enough to result in a nearly uniform ice thickness, that is expected to be observable in future missions.
Active Surface and Interior of Europa as a Potential Deep Habitat
Jupiter’s moon Europa may have an internal ocean of liquid water, along with the chemical compounds and energy source that life requires. Europa is covered by the solid icy shell, similar to other
Material transport across Europa's ice shell
Jupiter's moon Europa exhibits a deformed icy surface with salt deposits concentrated along the varied geological features. The topographic alignment of salt deposits has been speculated to indicate


Evaluation of models for the formation of chaotic terrain on Europa
Chaotic terrain on Europa is interpreted to be the result of the breakup of brittle surface materials over a mobile substrate. Two end-member models have been proposed for the mobile substrate: a
Geological evidence for solid-state convection in Europa's ice shell
The morphology and geological interpretation of distinct surface features—pits, domes and spots—discovered in high-resolution images of Europa obtained by the Galileo spacecraft are reported, finding that the formation of the features can be explained by thermally induced solid-state convection within an ice shell, possibly overlying a liquid water layer.
Topographic variations in chaos on Europa: Implications for diapiric formation
[1] Disrupted terrain, or chaos, on Europa, might have formed through melting of a floating ice shell from a subsurface ocean [Carr et al., 1998; Greenberg et al., 1999], or breakup by diapirs rising
A melt-through model for chaos formation on Europa
The character of chaotic terrain on Europa is consistent with its formation by the melting of a thin conducting ice shell from below. Tidal dissipation can provide adequate energy for such a process.
Evidence for a subsurface ocean on Europa
High-resolution Galileo spacecraft images of Europa are presented, in which evidence for mobile ‘icebergs’ is found and the detailed morphology of the terrain strongly supports the presence of liquid water at shallow depths below the surface, either today or at some time in the past.
Ice diapirs on Europa: Implications for liquid water
Early examinations of Galileo images of Europa revealed features that look like low topographic domes. These small (5–10 km in radius) domes have been interpreted as surface manifestations of
Convective instability in Europa's floating ice shell
Models of the tidally heated, floating ice shell proposed for the jovian satellite Europa generally find shell thicknesses less than 30 km. Past parameterized convection models indicated that such
Chaos on Europa
The characteristics of chaos regions on Europa suggest they may be sites of melt-through from below. They are wide ranging in size, location, and age. The largest are hundreds of kilometers across.
Brine mobilization during lithospheric heating on Europa: Implications for formation of chaos terrain, lenticula texture, and color variations
The background lineated plains on Europa are locally highly modified and destroyed in regions known as chaos and lenticulae. Produced there are (1) isolated fragments and polygons of background
Subglacial lakes and jökulhlaups in Iceland
Active volcanoes and hydrothermal systems underlie ice caps in Iceland. Glacier-volcano interactions produce meltwater that either drains toward the glacier margin or accumulates in subglacial lakes.
