Evaporation Reverses Groundwater Flow and Forms Hyper-Salinity

by D. Scott Mackay 4 December 20201 December 2022

A numerical model of groundwater-surface water systems shows how floodplain evaporation can reverse stream-groundwater flow and produce strong buoyancy changes associated with salinity.

Mmm, Salt—Europa’s Hidden Ocean May Contain the Table Variety

Katherine Kornei, Science Writer by Katherine Kornei 9 July 20197 March 2022

Hubble Space Telescope observations suggest that sodium chloride exists in young, geologically active regions on Europa, likely fed by upwelling from the moon’s subsurface ocean.

Chemical Patterns May Predict Stars That Host Giant Planets

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 25 June 20197 March 2022

Stars with giant planets tend to have a few key elements in abundance. A new algorithm used these patterns to predict hundreds of stars that will likely have exoplanets if we go looking for them.

Local Heat Source Needed to Form Liquid Water Lake on Mars

by Terri Cook 12 March 201910 March 2022

Thermal modeling suggests that active magmatism in the past few hundred thousand years could account for the presence of a large lake previously hypothesized beneath the Red Planet’s southern ice cap.

Waves of Deadly Brine Can Slosh After Submarine Landslides

Katherine Kornei, Science Writer by Katherine Kornei 28 January 201916 September 2022

Brine pools—hypersaline, low-oxygen waters deadly to many forms of ocean life—can experience waves hundreds of meters high when hit by a landslide, potentially overspilling their deep-sea basins.

Seeking Salt That Surfaces from Europa’s Hidden Ocean

Sarah Stanley, Science Writer by Sarah Stanley 31 January 20187 March 2022

Irradiation-induced color changes in sodium chloride could reveal whether it came from ocean water mixing with surface water, a key component of the moon’s potential to support life.
