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 …

Redox-sensitive trace metals have been used extensively as geochemical proxies to infer
the redox-status of marine sediments at the time of their deposition, and by extension, the …

The Carnian Pluvial Episode (Late Triassic) was a time of global environmental changes
and possibly substantial coeval volcanism. The extent of the biological turnover in marine …

The macronutrient phosphorus is thought to limit primary productivity in the oceans on
geological timescales. Although there has been a sustained effort to reconstruct the …

The cause of the end-Cretaceous mass extinction is vigorously debated, owing to the
occurrence of a very large bolide impact and flood basalt volcanism near the boundary …

Carbon fluxes in subduction zones can be better constrained by including new estimates of
carbon concentration in subducting mantle peridotites, consideration of carbonate solubility …

Eustatic sea-level changes of the Cretaceous are reevaluated based on a synthesis of
global stratigraphic data. A new terminology for local/regional or relative sea-level changes …

Although marine productivity is a key parameter in the global carbon cycle, reliable
estimation of productivity in ancient marine systems has proven difficult. In this study, we …

Ocean acidification may have severe consequences for marine ecosystems; however,
assessing its future impact is difficult because laboratory experiments and field observations …

Shallow-water carbonate sediments constitute the bulk of sedimentary carbonates in the
geologic record and are widely used archives of Earth's chemical and climatic history. One …
