Riverine Li isotope fractionation in the Amazon River basin controlled by the weathering regimes
Mathieu Dellinger,Mathieu Dellinger,Jérôme Gaillardet,Jérôme Gaillardet,Julien Bouchez,Damien Calmels,Pascale Louvat,Anthony Dosseto,Caroline Gorge,Lucia Alanoca,Laurence Maurice +10 more
TL;DR: In this paper, Li isotope composition of river-borne dissolved and solid material in the largest River system on Earth, the Amazon River basin, was analyzed to characterize Li isotopes fractionation at a continental scale.

Julie Cosmidis,Julie Cosmidis,Karim Benzerara,Guillaume Morin,Vincent Busigny,Oanez Lebeau,Didier Jézéquel,Vincent Noel,Gabrielle Dublet,Guillaume Othmane +9 more
TL;DR: In this paper, the depth variations of Fe and P speciation in Lake Pavin (Massif Central, France), a deep (bottom depth 92 m) and permanently stratified lake with anoxic and ferruginous conditions in the water column below 60 m depth.

EXAFS analysis of iron cycling in mangrove sediments downstream a lateritized ultramafic watershed (Vavouto Bay, New Caledonia)
Vincent Noel,Cyril Marchand,Cyril Marchand,Farid Juillot,Farid Juillot,Georges Ona-Nguema,Eric Viollier,Gregory Marakovic,Luca Olivi,Ludovic Delbes,Frédéric Gelebart,Guillaume Morin +11 more
TL;DR: In this paper, the distribution and speciation of Fe in mangrove sediments along a botanical gradient were determined by using X-ray absorption spectroscopy (XAS) at the Fe K-edge.
Journal ArticleDOI
Seasonal variability in concentration, composition, age, and fluxes of particulate organic carbon exchanged between the floodplain and Amazon River
Patricia Moreira-Turcq,Marie-Paule Bonnet,Marcelo Amorim,Marcelo Bernardes,Christelle Lagane,Laurence Maurice,Marcela A.P. Pérez,Patrick Seyler +7 more
TL;DR: In this article, the composition, sources, and age of particulate organic matter were determined in an Amazonian river-floodplain system during rising, high, falling, and low water periods over 7 yr (1999-2006).
Journal ArticleDOI
Glacial influence on the geochemistry of riverine iron fluxes to the Gulf of Alaska and effects of deglaciation
Andrew W. Schroth,John Crusius,John Crusius,F. Chever,Benjamin C. Bostick,Olivier Rouxel,Olivier Rouxel,Olivier Rouxel +7 more
TL;DR: In this article, the authors examined the source and chemical nature of riverine Fe input to the Gulf of Alaska (GoA) due to the widespread watershed deglaciation that is underway.

Geochemistry of the Amazon: 2. The influence of geology and weathering environment on the dissolved load
TL;DR: In the Amazon Basin, substrate lithology and erosional regime (seen in terms of transport-limited and weathering-limited denudation) exert the most fundamental control on the chemistry of surface waters within a catchment.

The ferrozine method revisited: Fe(II)/Fe(III) determination in natural waters
Eric Viollier,Patrick W. Inglett,Kimberley S. Hunter,Alakendra N. Roychoudhury,P. Van Cappellen +4 more
TL;DR: The original ferrozine method has been modified to sequentially determine the Fe(II)/Fe(III) speciation in small volumes of fresh and marine water samples, at the submicromolar level as discussed by the authors.
