Climatic Effects of Ocean Salinity on M Dwarf Exoplanets

Kyle Batra, Stephanie L. Olson

Ocean salinity is known to dramatically affect the climates of Earth-like planets orbiting Sun-like stars, with high salinity leading to less ice and higher surface temperature. Ho…

Superhabitability of High-Obliquity and High-Eccentricity Planets

Jonathan Jernigan, Émilie Laflèche, Angela Burke +1

Planetary obliquity and eccentricity influence climate by shaping the spatial and temporal patterns of stellar energy incident at a planet's surface, affecting both the annual mean…

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…

Earth as an Exoplanet. II. Earth's Time-variable Thermal Emission and Its Atmospheric Seasonality of Bioindicators

Jean-Noel Mettler, Sascha P. Quanz, Ravit Helled +2

We assess the dependence of Earth's disk-integrated mid-infrared thermal emission spectrum on observation geometries and investigate which and how spectral features are impacted by…

The Effect of Ocean Salinity on Climate and Its Implications for Earth's Habitability

Stephanie L. Olson, Malte F. Jansen, Dorian S. Abbot +2

The influence of atmospheric composition on the climates of present-day and early Earth has been studied extensively, but the role of ocean composition has received less attention.…
