Atmospheric CO2 over the Past 66 Million Years from Marine Archives
Throughout Earth's history, CO2 is thought to have exerted a fundamental control on
environmental change. Here we review and revise CO2 reconstructions from boron isotopes …

Ocean alkalinity, buffering and biogeochemical processes
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 …

Ocean carbon storage across the middle Miocene: A new interpretation for the Monterey Event
Abstract The Miocene Climatic Optimum (MCO, 14–17 Ma) was~ 3–4° C warmer than
present, similar to estimates for 2100. Coincident with the MCO is the Monterey positive …

The Cenozoic Seawater Conundrum: New constraints from Mg isotopes in island dolostones
Abstract The Mg/Ca ratio of seawater increased from∼ 1.5 to its present value of 5.4 over
the Neogene, indicating a fundamental imbalance in the Mg–Ca cycle during the late …

Limits to timescale dependence in erosion rates: Quantifying glacial and fluvial erosion across timescales
Earth's topography and climate result from the competition between uplift and erosion, but it
has been debated whether rivers or glaciers are more effective erosional agents. We …

Mg isotopes of siliciclastic sediments on continental marginal sea: Insights for the potential to trace silicate weathering
In the last decade, much attention has been devoted to Mg isotopic behavior during various
weathering processes. Nonetheless, whether Mg isotopes in terrigenous siliciclastic …
