Abstract: Mapping the history of atmospheric O2 during the late Precambrian is vital for evaluating potential links to animal evolution. Ancient O2 levels are often inferred from geochemical analyses of marine sediments, leading to the assumption… read more here.

DOI: 10.3390/atmos16111308
Abstract: Atmospheric carbon dioxide (CO2) levels are rising globally, yet their multiscale variability in remote oceanic regions remains poorly characterized. This study examines a 45-year monthly CO2 record (1980–2024) from the Azores, a subtropical North Atlantic… read more here.
