Journal ArticleDOI
Interlaboratory comparison study of Mg/Ca and Sr/Ca measurements in planktonic foraminifera for paleoceanographic research
Yair Rosenthal,Suzanne Perron-Cashman,Caroline H Lear,Edouard Bard,Stephen Barker,Katharina Billups,Martha Bryan,Margaret Lois Delaney,Peter B deMenocal,Gary S. Dwyer,Henry Elderfield,Chris German,Mervyn Greaves,David W. Lea,Thomas M Marchitto,Dorothy K. Pak,Georges L. Paradis,Ann D. Russell,Ralph R Schneider,Kathleen Scheiderich,Lowell D. Stott,Kazuyo Tachikawa,Eric Tappa,Robert C. Thunell,Michael W. Wara,Syee Weldeab,Paul A. Wilson +26 more
TL;DR: In this article, 13 laboratories from the USA and Europe participated in an intercomparison study of Mg/Ca and Sr/Ca measurements in foraminifera, including five planktonic species from surface sediments from different geographical regions and water depths.
Journal ArticleDOI
Copper speciation and isotopic fractionation in plants: uptake and translocation mechanisms.
Brooke M. Ryan,Jason K. Kirby,Fien Degryse,Hugh H. Harris,Mike J. McLaughlin,Mike J. McLaughlin,Kathleen Scheiderich +6 more
TL;DR: The lack of isotopic discrimination in oat plants suggests that Cu uptake and translocation are not redox selective, and the presence of isotopically light Cu in tomatoes is attributed to a reductive uptake mechanism, andThe isotopic shifts within various tissues are attributed to redox cycling during translocation.
Journal ArticleDOI
Global variability of chromium isotopes in seawater demonstrated by Pacific, Atlantic, and Arctic Ocean samples
Kathleen Scheiderich,Kathleen Scheiderich,Marghaleray Amini,Marghaleray Amini,Chris Holmden,Roger Francois +5 more
TL;DR: In this article, the authors presented multiple sites in the Arctic Ocean, and three locations in the Atlantic and Pacific Oceans, where the highest δ53Cr values occur in Pacific-sourced waters, which also have the lowest Cr concentration.
Journal ArticleDOI
Copper Isotope Fractionation during Equilibration with Natural and Synthetic Ligands
Brooke M. Ryan,Jason K. Kirby,Fien Degryse,Kathleen Scheiderich,Mike J. McLaughlin,Mike J. McLaughlin +5 more
TL;DR: The results show that complexation of Cu by organic ligands can affect the isotopic signature of the free Cu ion, which is considered the most bioavailable species, and highlight the importance of understanding fractionation processes in the uptake medium when using Cu isotopes to study the uptake mechanisms of organisms.
Journal ArticleDOI
Molybdenum isotope, multiple sulfur isotope, and redox-sensitive element behavior in early Pleistocene Mediterranean sapropels
TL;DR: In a recent study as mentioned in this paper, the same authors used geochemical redox proxies (Re, Mo, Mo isotopes, V, Fe/Al, and multiple S isotopes) in 8 sapropels from the Pleistocene to confirm water column euxinic conditions of varying intensity during sapropel deposition.
