Viruses in marine sediments: a review of their effect on biogeochemistry and microbial interactions [PDF]
Applied and Environmental MicrobiologyViruses are known to impact the flow of carbon through the environment, while also impacting the microbial community around them. While this has been reexamined in recent years in the marine water column, viral impacts on marine sediments, the microbes ...

Tidewater cycle drives alpine glacial sediment plume geochemistry [PDF]
Nature CommunicationsSediments transported by glacial meltwaters are important sources of trace-metal micronutrients for coastal microbial communities, linking cryospheric processes with ocean fertilization and biogeochemical cycles.

Combining colour parameters and geochemical tracers to improve sediment source discrimination in a mining catchment (New Caledonia, South Pacific Islands) [PDF]
SOIL, 2021 Tracing the origin of sediment is needed to improve our knowledge of hydro-sedimentary dynamics at the catchment scale. Several fingerprinting approaches have been developed to provide this crucial information.

Manganese incorporation in living (stained) benthic foraminiferal shells: a bathymetric and in-sediment study in the Gulf of Lions (NW Mediterranean) [PDF]
Biogeosciences, 2018 Manganese geochemistry in deep-sea sediments is known to vary greatly over the first few centimeters, which overlaps the in-sediment depth habitats of several benthic foraminiferal species.

Spatial variability of organic matter molecular composition and elemental geochemistry in surface sediments of a small boreal Swedish lake [PDF]
Biogeosciences, 2017 The composition of sediment organic matter (OM) exerts a strong control on biogeochemical processes in lakes, such as those involved in the fate of carbon, nutrients and trace metals.

Bacterial diversity and biogeochemistry of different chemosynthetic habitats of the REGAB cold seep (West African margin, 3160 m water depth) [PDF]
Biogeosciences, 2012 The giant pockmark REGAB (West African margin, 3160 m water depth) is an active methane-emitting cold seep ecosystem, where the energy derived from microbially mediated oxidation of methane supports high biomass and diversity of chemosynthetic ...

Central Tethyan platform-top hypoxia during Oceanic Anoxic Event 1a [PDF]
Climate of the Past, 2019 Short-term hypoxia in epeiric water masses is a common phenomenon of modern marine environments and causes mass mortality in coastal marine ecosystems.
