The microbial carbon pump and climate change
The ocean has been a regulator of climate change throughout the history of Earth. One key
mechanism is the mediation of the carbon reservoir by refractory dissolved organic carbon …

Snowball Earth climate dynamics and Cryogenian geology-geobiology
Geological evidence indicates that grounded ice sheets reached sea level at all latitudes
during two long-lived Cryogenian (58 and≥ 5 My) glaciations. Combined uranium-lead and …

Evolution of the global phosphorus cycle
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 …

Rise to modern levels of ocean oxygenation coincided with the Cambrian radiation of animals
The early diversification of animals (∼ 630 Ma), and their development into both motile and
macroscopic forms (∼ 575–565 Ma), has been linked to stepwise increases in the …

Authigenic carbonate and the history of the global carbon cycle
We present a framework for interpreting the carbon isotopic composition of sedimentary
rocks, which in turn requires a fundamental reinterpretation of the carbon cycle and redox …

Enigmatic origin of the largest-known carbon isotope excursion in Earth's history
Carbonate rocks from the Middle Ediacaran period in locations all over the globe record the
largest excursion in carbon isotopic compositions in Earth history. This finding suggests a …

The earliest Cambrian record of animals and ocean geochemical change
The Cambrian diversification of animals was long thought to have begun with an explosive
phase at the start of the Tommotian Age. Recent stratigraphic discoveries, however, suggest …
