Constraints on the Role of Marine Authigenic Clay Formation in Determining Seawater Lithium Isotope Composition Open
Silicate weathering reactions generate alkalinity that drives carbonate burial in the ocean, ultimately considered to balance solid‐earth CO 2 degassing. Because silicate weathering occurs at a climate dependent rate, it provides a negativ…

Denudation and weathering rates from meteoric 10Be/9Be: A versatile tool in mafic, carbonate or slate-dominated lithologies from the critical zone to very large catchments  Open
Meteoric 10Be is a cosmogenic nuclide produced in the atmosphere and delivered to Earth’s surface by precipitation, whereas stable 9Be is a trace metal released from bedrock during weathering. The ratio (10Be(meteoric)/9Be) is set in…

Climatic controls on leaf wax hydrogen isotope ratios in terrestrial and marine sediments along a hyperarid-to-humid gradient Open
The hydrogen isotope composition of leaf wax biomarkers (δ2Hwax) is a valuable tool for reconstructing continental paleohydrology, since it serves as a proxy for the hydrogen isotope composition of precipitation (δ2Hpre). To yield robust p…

Transport and accumulation of litter in submarine canyons: a geoscience perspective Open
Marine litter is one of the most pervasive and fast-growing aspects of contamination in the global ocean, and has been observed in every environmental setting, including the deep seafloor where little is known about the magnitude and conse…

Controls on global submarine canyon occurrence and formation processe s– Insights from Spatial Point Pattern Analysis – Open
Submarine canyons are the main conduits that transport material such as sediment, organic carbon, and litter from the continent to the deep sea. This transport of material is more efficient when the canyon heads incise into the shelf, as o…
