The study, “Lower Triassic carbonate δ238U record demonstrates expanded ocean anoxia during Smithian Thermal Maximum and improved ventilation during Smithian-Spathian boundary cooling event,” was published in the journal Palaeogeography, Palaeoclimatology, Palaeoecology. The work was supported by NASA Astrobiology through the Exobiology Program. This newly-revealed science is also a critical part of NASA’s work to understand the Universe, advance human exploration, and inspire the next generation. As NASA’s Artemis program moves forward with human exploration of the Moon, the search for life on other worlds remains a top priority for the agency.
