Tests of seismic attenuation show fluid saturation and high pressure near a seismic source reduce high-frequency content, challenging the idea of slow slip as the cause of low-frequency earthquakes.

Rotation of Europa’s Icy Shell Driven by Deep Ocean Currents
A model using currents in the deep ocean to drive rotation of Europa’s ice shell from below can explain why its surface may drift despite being tidally locked.

Clues from a Subglacial Lake for Holocene Grounding Line Change
Organic carbon sampled in the lake contained radiocarbon, indicating connection to the ocean in the mid-Holocene, when the grounding line was up to 260 kilometers inland of its current position.

The Depleted Mantle Merry-Go-Round
Abyssal peridotites show through their isotopic composition a complex history. From differences we can infer the existence of ultra depleted mantle and an uneven contribution to ridge magmatism.
