Alpha radiation from polymetallic nodules and potential health risks from deep-sea mining
Autor: Jessica B. Volz, Walter Geibert, Dennis Köhler, Michiel M. Rutgers van der Loeff, Sabine Kasten
Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-10 (2023)
Abstract In search for critical elements, polymetallic nodules at the deep abyssal seafloor are targeted for mining operations. Nodules efficiently scavenge and retain several naturally occurring uranium-series radioisotopes, which predominantly emit

Data report: solid-phase major and minor elements and iron and sulfur species in sediments of the Anholt Basin, Baltic Sea collected during IODP Expedition 347
Autor: Dalton S. Hardisty, Jessica B. Volz, Sabine Kasten, Natascha Riedinger
In this report, we present bulk solid-phase major and minor element contents and Fe and S species in sediments from Site M0060 in the Anholt Basin recovered during Integrated Ocean Drilling Program Expedition 347 to the Baltic Sea. Site M0060 is char

Impact of depositional regimes on biogeochemical cycling of iron and stable Fe signatures in sediments from the Argentina Continental Margin
Autor: Simone A Kasemann, Anette Meixner, Jessica B. Volz, Elda Miramontes, Thomas Frederichs, Anne-Christin Melcher, Sabine Kasten, Male Köster, Susann Henkel, Thomas Pape
The Argentina Continental Margin represents a unique geologic setting where fundamental interactions between bottom currents and sediment deposition as well as their impact on biogeochemical processes and element cycling, in particular iron, can be s

Impact of simulated deep-sea polymetallic nodule mining on sediment and pore-water geochemistry in prospective mining areas in the NE Pacific Ocean
Autor: Laura Haffert, Sabine Kasten, Jessica B. Volz, Andrea Koschinsky, Matthias Haeckel
Industrial-scale harvesting of deep-sea mineral resources, such as polymetallic nodules, is likely to have severe consequences for the natural environment. However, the effects of mining activities on deep‑sea ecosystems, sediment geochemistry and

Diagenetic manganese and iron cycling and implications for past redox conditions in sediments along the Emperor Seamount Chain, NW Pacific Ocean
Autor: Denise Bethke, Weng-Si Chaoa, Jessica B. Volz, Annika Schnakenberg, Ingrid Dohrmann, Ingrid Stimac, Walter Geibert, Sabine Kasten
The deep water of the North Pacific Ocean is enriched in CO2 and nutrients as a result of organic matter degradation in the water column and surface sediments. Due to its large volume, the deep North Pacific may have played a fundamental role for the

Post-depositional manganese mobilization during the last glacial period in sediments of the eastern Clarion-Clipperton Zone, Pacific Ocean
Autor: Andrea Koschinsky, Jessica B. Volz, Bo Liu, Susann Henkel, Sabine Kasten, Male Köster
Publikováno v: EPIC3Earth and Planetary Science Letters, ELSEVIER SCIENCE BV, 532(116012), ISSN: 0012-821X
Numerous studies have provided compelling evidence that the Pacific Ocean has experienced substantial glacial/interglacial changes in bottom-water oxygenation associated with enhanced carbon dioxide storage in the glacial deep ocean. Under postulated

The manganese nodule belt within the Clarion and Clipperton Fracture Zones (CCZ) in the abyssal NE Pacific Ocean is characterized by numerous seamounts, low organic matter (OM) depositional fluxes and meter-scale oxygen penetration depths (OPD) into
