The rare earth elements in rivers, estuaries, and coastal seas and their significance to the composition of ocean waters
TLDR
The concentrations of rare earth elements (REEs) in samples from 15 rivers, from 6 estuarine transects, and of 5 coastal seawaters are reported and have been used with literature data to examine the continuity in average REE pattern between average continental crust and the dissolved input of REE to the oceans via estuaries.About:

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).

Trace Elements in River Waters
TL;DR: In this article, the authors reviewed the recent literature on trace elements in rivers, in particular by incorporating the results derived from recent ICP-MS measurements, and the basic questions which they want to address are the following: What are the trace element levels in river waters? What controls their abundance in rivers and fractionation in the weathering+transport system?

Rare earth elements in pore waters of marine sediments
TL;DR: In this paper, the rare earth elements (REEs) were measured in pore waters of the upper ∼25 cm of sediment from one site off Peru and three sites on the California margin.

Rare earth element geochemistry of Late Devonian reefal carbonates, Canning Basin, Western Australia : Confirmation of a seawater REE proxy in ancient limestones
TL;DR: In this article, rare earth element and yttrium (REE+Y) concentrations were determined in 49 Late Devonian reefal carbonates from the Lennard Shelf, Canning Basin, Western Australia, and the results suggest that most limestones should record important aspects of the REE geochemistry of the waters in which they precipitated, provided they are relatively free of terrigenous contamination and major diagenetic alteration from fluids with high, non-seawater-like REE contents.

Chemical and physical denudation in the Amazon River Basin
TL;DR: In this article, major and trace element data on the suspended and dissolved phases of the Amazon River and its main tributaries are presented, where the proportions derived from different sources are calculated.

Ferrozine---a new spectrophotometric reagent for iron
TL;DR: The ferroin group has been known to react as bidentate ligands with certain metal ions such as ferrous, cuprous, and cobaltous, to give colored complex species.

The rare earth elements in seawater
Henry Elderfield,Mervyn Greaves +1 more
TL;DR: In this article, the depth distributions of La, Ce, Nd, Sm, Eu, Gd, Dy, Er and Yb in the oceanic water column are used to evaluate the marine geochemical cycle of the rare earth elements and their application as water-mass tracers.

Flocculation of dissolved organic and inorganic matter during the mixing of river water and seawater
TL;DR: In this paper, a new approach to estuarine studies is presented which establishes 1) the extent and salinity dependence of non-conservative behaviour; 2) composition and chemical form of removal products; and 3) abiological removal mechanisms.
Journal ArticleDOI
Mobility and fractionation of rare earth elements during weathering of a granodiorite
TL;DR: The rare earth elements (REE) have been mobilised and fractionated during supracrustal alteration of the Torrongo granodiorite as mentioned in this paper, and the residual products are especially depleted in the heavy REE.

The mechanism of iron removal in estuaries
TL;DR: A survey of U.S. east coast estuaries confirms that large-scale rapid removal of iron from river water is a general phenomenon during estuarine mixing as discussed by the authors.
