A memory of Paleozoic to Quaternary Greenhouse climates recorded in Southern African regolith

Abstract In this article, we explore the potential of iron-rich duricrust regoliths from old erosional anorogenic surfaces to record clues of the long-term continental paleoclimatic evolution. We coupled geochemical, mineralogical and geochronological analyses on iron oxides and...

Ediacaran coupling of climate and biosphere dynamics

Climate change is demonstrably linked to radiations, extinctions, and turnovers in the biosphere throughout the Phanerozoic (538.8 Ma to present). Here, we suggest this connection existed as early as the late Ediacaran (ca. 579−538.8 Ma), the first interval in Earth’s history to...

Trace Elements in Total Atmospheric Deposition Directly Measured Over the Caribbean Region: Natural Versus Anthropogenic Sources and Geographic Origin

Abstract Dust, sea salt, and anthropogenic and biogenic particles in total atmospheric deposition are sources of essential elements that can significantly impact biogeochemical cycles in the Atlantic Ocean and in islands of the Caribbean region. This unique 41‐month data set reco...

Seasonal dependence of temperate forest soil respiration to soil temperature and water content clarified through data-driven modeling

Soil respiration is commonly modelled as a function of soil temperature and soil moisture, without explicitly accounting for seasonal effects. We have therefore developed a data-driven model that integrates interactions among soil temperature, soil moisture, and seasonality. This...
