Evidence of an Extended Alfvén Wing System at Enceladus: Cassini's Multi‐Instrument Observations
Abstract We report in situ evidence for Enceladus' Alfvén wing system and its coupling with Saturn's ionosphere, based on multi‐instrument observations from the Cassini spacecraft. Analysis of 36 events, including 13 from non‐flyby paths, confirms the existence of a Main Alfvén Wing (MAW) current system generated at Enceladus, and associated Reflected ...

Export fluxes in a naturally iron-fertilized area of the Southern Ocean – Part 1: Seasonal dynamics of particulate organic carbon export from a moored sediment trap [PDF]
A sediment trap moored in the naturally iron-fertilized Kerguelen Plateau in the Southern Ocean provided an annual record of particulate organic carbon and nitrogen fluxes at 289 m. At the trap deployment depth, current speeds were typically low (~ 10

Stress Barriers and Their Impact on Rupture Propagation
Abstract Earthquake ruptures often exhibit complex behaviors, including abrupt arrest followed by delayed re‐nucleation. While on‐fault stress heterogeneity is a recognized contributing factor, as it can arrest or slow down rupture propagation, its interaction with propagating ruptures remains complex and not fully understood. Here, we study frictional

The first observed stellar occultations by the irregular satellite Phoebe (Saturn IX) and improved rotational period [PDF]
peer reviewedWe report six stellar occultations by Phoebe (Saturn IX), an irregular satellite of Saturn, obtained between mid-2017 and mid-2019. The 2017 July 6 event was the first stellar occultation by an irregular satellite ever observed.

Abstract This study presents the first high‐resolution spatial and temporal analysis of wind flow, sediment transport and topographic evolution under simultaneous storm conditions across two morphologically contrasting beach‐dune systems, characterized by a gently sloping dune face (11°) and a steep, scarped dune face (36°).
