Atmospheric carbon depletion as a tracer of water oceans and biomass on temperate terrestrial exoplanets

Kavli Affiliate: Sara Seager | First 5 Authors: Amaury H. M. J. Triaud, Julien de Wit, Frieder Klein, Martin Turbet, Benjamin V. Rackham | Summary: The conventional observables to identify a habitable or inhabited environment in exoplanets, such as an ocean glint or abundant atmospheric O$_2$, will be challenging to detect with present or upcoming […]
