Ice fabric in an Antarctic ice stream interpreted from seismic anisotropy

Editors’ Highlight—

Large-scale ice flow models assume that ice is isotropic, but this study suggests the presence of highly anisotropic ice within a fast-flowing ice stream in West Antarctica. The authors analyzed the shear wave splitting of events generated on the bed of the ice stream. From the delay time, they derived the deviation of the shear wave velocity to the isotropic velocity, and from this they inferred that the fabric is a mix of horizontal partial girdle and cluster fabric. This anisotropic fabric type has not been observed in glaciers before.

Early Results: Juno at Jupiter 

Early results from Juno's mission at Jupiter including approach to Jupiter and the first perijove pass (PJ1). Juno's scientific objectives include the study of Jupiter's interior, atmosphere and polar magnetosphere with the goal of understanding Jupiter's origin, formation and evolution. This collection of papers provides early results from Juno's measurements of the gravity and magnetic fields, deep atmospheric microwave sounding, infrared, visible and ultraviolet images/spectra and an array of fields and particles instruments as well as context for the early results with respect to current theory and models of Jupiter's formation and evolution. Topics include both Juno - Jupiter related theoretical models and data analysis as well as collaborative observations made from Earth based assets.
