Olga Verkhoglyadova, 2024, "Temporal Variability of Equatorial Ionization Anomaly Crest Locations Extracted from Global Ionospheric Maps", https://doi.org/10.48577/jpl.VWPE33, Space Weather, JPL Open Repository
The Equatorial Ionization Anomaly (EIA) crest location is known to vary over a variety of temporal scales. For the first time we perform a statistical survey of the temporal variation of the EIA crest location viewed globally and spanning 20 years. We extract the crest location f... |

Joana Voigt, 2024, "Unraveling Geologic Processes and Aqueous Alteration at Tyrrhena Terra, Mars", https://doi.org/10.48577/jpl.OXSPKN, JGR: Planets, JPL Open Repository
The central eastern Tyrrhena Terra region of Mars contains abundant aqueously altered minerals including Fe/Mg-smectites, smectite/chlorite mixtures, chlorites, zeolites, and carbonates. This study relates detections of these alteration-generated materials with mafic outcrops, ge... |
