Dr. Richard Ernst, the Scientist in Residence at the Department of Earth Sciences, has had a manuscript accepted into Nature Communications.
This paper provides geological evidence in support of a dramatic climate change event on Venus. In this "Great Climate Change Event", Venus went from Earth-like to hyper-warm (450C) conditions likely due to extensive volcanism, CO2 release and a runaway greenhouse effect that evaporated the oceans.
Paper Title: Tesserae on Venus may preserve evidence of fluvial erosion
Authors: Sara Khawja, Richard E. Ernst, Claire Samson, Paul K. Byrne, Richard C. Ghail, Lauren MacLellan
Two of the authors are Carleton University Earth Science students:
- Sara Khawja was Dr. Ernst's MSc student (co-supervised with Claire Samson)
- Lauren MacLellan is a 3rd year Undergraduate student who started working with Dr. Ernst (mapping on Venus) 2 years ago, at the end of her first year when she received the DSRI (Dean's Summer Research Internship). She has a separate MacLellan et al. manuscript on her detailed mapping of a volcanic region of Venus that is currently in review in Earth-Science Reviews
