Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …

Seawater reverse osmosis (SWRO) desalination facilities produce freshwater and, at the
same time, discharge hypersaline brine that often includes various chemical additives such …

Deep-seafloor organisms consume oxygen, which can be measured by in situ benthic
chamber experiments. Here we report such experiments at the polymetallic nodule-covered …

The urgent need for effective climate change mitigation has spurred the exploration of
various negative emission technologies (NETs). Here, we investigate recent advancements …

Cycling of organic carbon in the ocean has the potential to mitigate or exacerbate global
climate change, but major questions remain about the environmental controls on organic …

We first review dissolved organic matter (DOM) concentrations and isotopic composition
(carbon only) in sediment pore waters at both the bulk level and at the compound and …

Rhenium (Re) and uranium (U) are essential proxies in reconstructing past oceanic
oxygenation evolution. However, their removal in continental shelf sediments, hotspots of …

The radiation of bioturbation during the Ediacaran–Cambrian transition has long been
hypothesized to have oxygenated sediments, triggering an expansion of the habitable …

The quantification of anaerobic oxidation of organic matter in the global seabed is to a large
extent based on transport-reaction modeling of pore water ions involved in the …

We assessed the relationship between rates of biological energy utilization and the biomass
sustained by that energy utilization, at both the organism and biosphere level. We compiled …
