but decreased ammonium and silicate concentration in the upper sediment layers. The effects of fauna and bioturbation potential on biogeochemistry were very limited in both mud and sand habitats. Our ...

Benthic ecosystems, which include the sediments and organisms at the bottom of aquatic environments, play a crucial role in nutrient cycling and overall ecosystem health. Bioturbation, the process ...

Marine sediments are extremely diverse and cover the majority of the Earth's surface. By stirring up and churning the seafloor—a process known as "bioturbation"—small creatures living in the ...

For instance, greigite formation was observed in deep-sea sediments influenced by turbidites and bioturbation, indicating that these processes can enhance the preservation of magnetic signals in ...
