Fig. 5. Reflective green edge from haloarchaeal pigments.
A laboratory reflection spectrum of H. lacusprofundi (top panel) and an environmentally characterized halophile bloom under a simulated Earth atmosphere (bottom panel), including atmospheric absorption and scattering, are shown, plotting wavelength in nanometers (nm) (abscissa) versus percent reflectivity (ordinate) (DasSarma and Schwieterman 2019). Dashed lines are shown for reference and strong water (H2O) and oxygen (O2) interference bands labeled.
