My name is Jacob Poore, and I am from East Providence, Rhode Island. Here at Wesleyan, I am a Junior studying Physics and Integrated Design Engineering (IDEAS) with the aim to enter graduate school for Mechanical/Aerospace Engineering in the near future. I am also a member of the Wesleyan University Varsity Wrestling Team.
Abstract: This study examines 38,657 Martian impact craters to test whether ejecta complexity predicts depth-diameter (d/D) ratios, a key metric encoding impact energy and subsurface conditions. While complex ejecta craters show significantly higher d/D ratios than simple ejecta craters (p < 0.001), ejecta complexity explains less than 0.2% of variance in crater geometry. In contrast, geographic factors, particularly latitude and its interaction with crater diameter, explain 42% of variance, with high-latitude craters showing systematically shallower depths independent of ejecta type. These findings reveal that latitude-dependent subsurface ice dominates crater morphology. The results challenge assumptions that ejecta patterns reliably preserve impact physics and demonstrate that environmental context is essential for crater classification, surface dating, and automated detection algorithms.
