Alkalinity, the excess of proton acceptors over donors, plays a major role in ocean chemistry,
in buffering and in calcium carbonate precipitation and dissolution. Understanding alkalinity …

Subduction of lithospheric plates at convergent margins leads to transport of materials once
close to or at the surface of Earth to great depths. Some of them later return to the surface by …

The Cenozoic era (66 to 0 million years) is marked by long-term aberrations in carbon
cycling and large climatic shifts, some of which challenge the current understanding of …

The shape of the ocean floor (bathymetry) and the overlaying sediments provide the largest
carbon sink throughout Earth's history, supporting~ one to two orders of magnitude more …

Estimates of sedimentary organic carbon burial fluxes based on inventory and isotope mass
balance methods have been divergent. A new calculation of the isotope mass balance using …

The middle Miocene climate transition∼ 14 Ma marks a fundamental step towards the
current “ice-house” climate, with a∼ 1‰ δ 18 O increase and a∼ 1‰ transient δ 13 C rise in …

We investigate if the commonly neglected riverine detrital carbonate fluxes might
reconciliate several chemical mass balances of the global ocean. Particulate inorganic …

Constraining rates of marine carbonate burial through geologic time is critical for interpreting
reconstructed changes in ocean chemistry and understanding feedbacks and interactions …

The global geochemical cycles of calcium and strontium in seawater link the chemical
composition of the oceans to the global carbon cycle and Earth's climate through the …

Terrigenous materials are transported to the ocean via various pathways, which can modify
the weight contents of calcium carbonate (wt% CaCO3) in marine sediment and mask …
