Dynamics of a Snowball Earth ocean [PDF]
Nature, 2013 Geological evidence suggests that marine ice extended to the Equator at least twice during the Neoproterozoic era (about 750 to 635 million years ago), inspiring the Snowball Earth hypothesis that the Earth was globally ice-covered. In a possible Snowball Earth climate, ocean circulation and mixing processes would have set the melting and freezing ...

Carbon cycling and snowball Earth [PDF]
Nature, 2008 The possibility that Earth witnessed episodes of global glaciation during the latest Precambrian challenges our understanding of the physical processes controlling the Earth's climate. Peltier et al. suggest that a 'hard snowball Earth' state may have been prevented owing to the release of CO(2) from the oxidation of dissolved organic carbon (DOC) in ...

Resilience of Snowball Earth to Stochastic Events [PDF]
Geophysical Research LettersEarth went through at least two periods of global glaciation (i.e., “Snowball Earth” states) during the Neoproterozoic, the shortest of which (the Marinoan) may not have lasted sufficiently long for its termination to be explained by the gradual volcanic

16th International Conference on Meteorology, Climatology and Atmospheric Physics—COMECAP 2023, 2023 Throughout the history of Earth, significant changes in its climate and consequent alterations to its surface have been recorded. One of the most extreme forms is the complete coverage of the planet by ice, known as Snowball Earth. This theory explains numerous findings from archaeological studies conducted worldwide during the Neoproterozoic Period ...

Bisnorgammacerane traces predatory pressure and the persistent rise of algal ecosystems after Snowball Earth [PDF]
Nature Communications, 2019 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]
Nature Communications, 2016 Large positive sulphur isotope excursions, recorded in the wake of the Marinoan glaciation have previously been interpreted assuming stable ocean sulphate concentrations.
