Physiological limits to life in anoxic subseafloor sediment
In subseafloor sediment, microbial cell densities exponentially decrease with depth into the
fermentation zone. Here, we address the classical question of'why are cells dying faster than …

Sedimentary parameters control the sulfur isotope composition of marine pyrite
Reconstructions of coupled carbon, oxygen, and sulfur cycles rely heavily on sedimentary
pyrite sulfur isotope compositions (δ34Spyr). With a model of sediment diagenesis, paired …
