Bisnorgammacerane traces predatory pressure and the persistent rise of algal ecosystems after Snowball Earth [PDF]
It remains unclear when and why the world’s oceans, once largely occupied by bacteria, became dominated by photosynthetic algae. Here, using fossil lipids in million year old rocks, the authors show that predation after the Snowball Earth glaciations ...

Multiple sulfur isotope evidence for massive oceanic sulfate depletion in the aftermath of Snowball Earth [PDF]
Large positive sulphur isotope excursions, recorded in the wake of the Marinoan glaciation have previously been interpreted assuming stable ocean sulphate concentrations.

Maintenance of the great late Ediacaran ice age [PDF]
Geological records witness extensive glaciations in the late Ediacaran, ranging from ~580 to 560 Ma or younger. However, the explanation of maintenance for this regionally diachronous and globally continuous glacial epoch is still unclear.

Initiation of a Marinoan Snowball Earth in a state-of-the-art atmosphere-ocean general circulation model [PDF]
We study the initiation of a Marinoan Snowball Earth (~635 million years before present) with the state-of-the-art atmosphere-ocean general circulation model ECHAM5/MPI-OM. This is the most sophisticated model ever applied to Snowball initiation.

A conceptual model of oceanic heat transport in the Snowball Earth scenario [PDF]
Geologic evidence suggests that the Earth may have been completely covered in ice in the distant past, a state known as Snowball Earth. This is still the subject of controversy, and has been the focus of modeling work from low-dimensional models up to ...

Ocean ventilation is an important regulator for atmospheric CO2 level (pCO2) by affecting the relative proportion of carbon stored in the atmosphere and deep ocean.
