Sediment fluxes to the seafloor govern fate of elements and compounds in ocean serve as a prerequisite for research on elemental cycling, benthic processes sediment management strategies. To quantify these over areas, it is necessary scale up mass accumulation rates (MAR) obtained from multiple sample stations. Conventional methods spatial upscaling involve averaging data or interpolation. However, approaches may not be sufficiently precise account variations MAR, leading poorly constrained...
Dissolved silicate (H 4 SiO ) is essential for the formation of opaline skeletal structures diatoms and other siliceous plankton. A fraction particulate biogenic silica (bSi) formed in surface waters sinks to seabed, where it either dissolves returns water column or permanently buried. Global budgets are still poorly constrained since data on benthic bSi cycling lacking, especially continental margins. This study describes Skagerrak, a sedimentary depocenter particles from North Sea....
The Skagerrak basin represents the main sink area for fine-grained sediment in North Sea region and constitutes a natural deposition center sediments that are supplied from Atlantic, Baltic surrounding continental margins coasts. However, exact sources their proportional contributions to deposits not well understood. To trace predominant of gain better understanding sedimentary processes basin, radiogenic Sr, Nd, Hf isotope signatures clay mineral compositions detrital fraction surface...
Abstract End‐member modelling of bulk grain‐size distributions allows the unravelling natural and anthropogenic depositional processes in salt marshes quantification their respective contribution to marsh accretion. The sedimentology two is presented: (1) a sheltered back‐barrier marsh; (2) an exposed, reinstated foreland marsh. Sedimentological data are supplemented by age model based on lead‐210 decay caesium‐137, as well geochemical data. shows that growth settings primarily controlled...
Since industrial times, human and natural processes have affected the sediment system of North Sea. As a substantial proportion suspended in Sea is ultimately deposited Skagerrak, it offers representative archive for reconstructing temporal variability system. However, little known about how sedimentation rates Skagerrak may changed over time. In this study, we present high-resolution age-depth models based on radionuclide 210Pb anthropogenic time markers 137Cs, 14C mercury to determine...
