Evaluating the Plausible Range of N2O Biosignatures on Exo-Earths: An Integrated Biogeochemical, Photochemical, and Spectral Modeling Approach
Edward W. Schwieterman, Stephanie L. Olson, Daria Pidhorodetska +7
Nitrous oxide (N2O) -- a product of microbial nitrogen metabolism -- is a compelling exoplanet biosignature gas with distinctive spectral features in the near- and mid-infrared, an…
The future lifespan of Earth's oxygenated Atmosphere
K. Ozaki, C. Reinhard
Earth's modern atmosphere is highly oxygenated and is a remotely detectable signal of its surface biosphere. However, the lifespan of oxygen-based biosignatures in Earth's atmosphe…
Constraining Prebiotic Chemistry Through a Better Understanding of Earth's Earliest Environments
Timothy W. Lyons, Karyn Rogers, Ramanarayanan Krishnamurthy +5
Any search for present or past life beyond Earth should consider the initial processes and related environmental controls that might have led to its start. As on Earth, such an und…
Oceanic and atmospheric methane cycling in the cGENIE Earth system model
Christopher T. Reinhard, Stephanie L. Olson, Sandra Kirtland Turner +3
The methane cycle is a key component of the Earth system that links planetary climate, biological metabolism, and the global biogeochemical cycles of carbon, oxygen, sulfur, and hy…
Exogeoscience and Its Role in Characterizing Exoplanet Habitability and the Detectability of Life
Cayman T. Unterborn, Paul K. Byrne, Ariel D. Anbar +24
The search for exoplanetary life must encompass the complex geological processes reflected in an exoplanet's atmosphere, or we risk reporting false positive and false negative dete…
A sluggish mid-Proterozoic biosphere and its effect on Earth's redox balance
Kazumi Ozaki, Christopher T. Reinhard, Eiichi Tajika
The possibility of low but nontrivial atmospheric oxygen (O2) levels during the mid-Proterozoic (between 1.8 and 0.8 billion years ago, Ga) has important ramifications for understa…
