Evaluation of Aliasing in Aeromagnetic Surveys ‐ Update to Reid 1980 Analysis
Abstract Regularly spaced magnetic anomaly surveys, consisting of parallel traverse lines and perpendicular (more widely spaced) tie lines, are routinely collected for multiple applications including geologic studies and, more recently, as reference for alternative magnetic navigation. A key factor…

Impact‐Generated Mixing, Melting and Vaporization of the Early Earth's Crust
Abstract Earth's primary accretion was followed by a protracted flux of interplanetary collisions by leftover planetesimals. The effects of the largest collisions—with bodies possibly exceeding 1,000 km diameter—would have been devastating for terrestrial near‐surface environments. While our…

Morphological Evolution of Impact Craters and Associated Gravity Anomalies: New Perspectives From Numerical Modeling
Abstract Hyper‐velocity impacts on planetary surfaces lead to impact craters whose morphology evolves due to exogenous factors such as atmospheric processes, as well as endogenous factors including tectonic and metamorphism. On Earth, erosion processes driven by climate (fluvial, aeolian, glacial…

High Latitude Dayside Aurora Ionospheric Electrodynamics Using Data Assimilation
Abstract Under favorable conditions, the interaction between the interplanetary magnetic field (IMF) and Earth's magnetic field can result in a dayside aurora at magnetic latitudes above approximately 80°, referred to as the high latitude dayside Aurora (HiLDA). This term broadly includes several…
