Ultraviolet protection on a snowball Earth [PDF]
, 2001 Habitats in the Antarctic provide an insight into habitats available on snowball earth. Physical UV protection on snowball earth would have been dominated by the manifestations of ice and snow in different habitats.

Snowball Earth, population bottleneck and Prochlorococcus evolution. [PDF]
Proc Biol Sci, 2021 Prochlorococcus are the most abundant photosynthetic organisms in the modern ocean. A massive DNA loss event occurred in their early evolutionary history, leading to highly reduced genomes in nearly all lineages, as well as enhanced efficiency in both ...

Initiation of a Marinoan Snowball Earth in a state-of-the-art atmosphere-ocean general circulation model [PDF]
Climate of the Past, 2011 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]
Earth System Dynamics, 2016 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 ...

Frontiers in Earth Science, 2022 The history of the nitrogen cycle on Earth is linked to the redox evolution of the surface environment. Many nitrogen cycle fluxes are microbially mediated, and the particular fluxes operating at any given time in an ecosystem depend on the presence ...

Climate and ocean circulation in the aftermath of a Marinoan snowball Earth [PDF]
Climate of the Past, 2022 When a snowball Earth deglaciates through a very high atmospheric CO2 concentration, the resulting inflow of freshwater leads to a stably stratified ocean, and the strong greenhouse conditions drive the climate into a very warm state.
