Abstract Chemical weathering and the ensuing atmospheric carbon dioxide consumption has long been considered to work on geological time periods until recently when some modelling natural records have shown that weathering-related CO 2 can change at century glacial-interglacial scale. Last glacial interglacial transition period is a best test case understand interplay between Pco -temperature-chemical pulse of rapid chemical was initiated. Here we show, from high resolution 54 ka record...
Abstract A regional solid‐phase phosphorus (P) speciation study in the Central Indian Basin (CIB) was carried out to elucidate spatial distribution of sedimentary P species and diagenesis an oligotrophic setting. The results show that enrichment is order biogenic (P bio ) > authigenic auth iron bound Fe detrital det organic org P. higher concentrations are found siliceous oozes, which attributed high biological productivity overlying waters compared pelagic clay region. High contents with...
