Journal ArticleDOI
Ocean particle chemistry: The fractionation of rare earth elements between suspended particles and seawater
TL;DR: In this paper, a new method is explored for estimating the residence time of suspended particles by combining the Ce concentration data of dissolved and surface-bound phases with the Ce(III) oxidation rate measurements of MOFFETT (1990).
Journal ArticleDOI
The Aquatic Chemistry of Rare Earth Elements in Rivers and Estuaries
TL;DR: In this article, a comparison of field and laboratory experiments highlights key features of rare earth element fractionation in major river systems is presented, showing that the dissolved pool of both rivers is highly HREE enriched with respect to the REE composition of their suspended particles.
Book ChapterDOI
Chapter 158 Marine chemistry and geochemistry of the lanthanides
R.H. Byrne,E.R. Sholkovitz +1 more
TL;DR: In this paper, the characteristics and properties of lanthanides in seawater and the rationale for studying the lanthanide composition of natural waters are discussed, as well as the biogeochemical and physical processes responsible for these distributions.
Journal ArticleDOI
A new approach to the nd residence time in the ocean : the role of atmospheric inputs
TL;DR: In this paper, the authors present direct evidence of the rare earth elements isotopic exchange between particulate lithogenic fraction and seawater without significant mass transfer, and suggest that the partial dissolution of atmospheric fallout is probably one of the main rare earth element sources of the ocean.
Journal ArticleDOI
The distribution and speciation of iron along 6°E in the Southern Ocean
TL;DR: The distribution and speciation of iron were determined along a transect in the eastern Atlantic sector (6°E) of the Southern Ocean during a collaborative Scandinavian/South African Antarctic cruise conducted in late austral summer (December 1997/January 1998) as discussed by the authors.

Journal ArticleDOI
Oceanographic distributions of cadmium, zinc, nickel, and copper in the North Pacific
TL;DR: The vertical profiles of Cd, Zn, Ni, and Cu have been determined at three stations in the North Pacific and in the surface waters on a transect from Hawaii to Monterey, California as discussed by the authors.
Journal ArticleDOI
A chemical technique for the separation of ferro-manganese minerals, carbonate minerals and adsorbed trace elements from pelagic sediments
Roy Chester,M.J. Hughes +1 more
TL;DR: In this paper, a method is described which may be used to separate chemically those trace elements incorporated into pelagic sediments by ferro-manganese nodules, carbonate minerals (excluding dolomite) and by adsorption onto mineral surfaces.
Journal ArticleDOI
Sampling and analytical methods for the determination of copper, cadmium, zinc, and nickel at the nanogram per liter level in sea water
TL;DR: In this paper, a dithiocarbamate extraction method coupled with atomic absorption spectrometry and electrothermal atomization is described which is essentially 100% quantitative for each of the four metals studied.
Journal ArticleDOI
The contrasting biogeochemistry of iron and manganese in the Pacific Ocean
TL;DR: In this article, the vertical and horizontal distributions of dissolved and suspended particulate Fe and Mn, and vertical fluxes of these metals (obtained with sediment traps) were determined throughout the Pacific Ocean.
