The behaviour of dissolved organic material, iron and manganese in estuarine mixing
TLDR
Fractionation by ultra-filtration of the dissolved organic material (DOM) in the River Beaulieu, with typical concentrations of dissolved organic carbon (DOC) of 7-8 mg C/l, showed it to be mainly in the nominal molecular weight range of 103-105, with 16-23% of the total DOC in the fraction > 105 as mentioned in this paper.About:

Organic geochemistry of natural waters
TL;DR: The first part of the book as mentioned in this paper is a general overview of the amount and general nature of dissolved organic carbon in natural waters, and the second part is a summary of the data that has accumulated from many disciplines over the last decade.
Journal ArticleDOI
The rare earth elements in rivers, estuaries, and coastal seas and their significance to the composition of ocean waters
TL;DR: 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.
Journal ArticleDOI
A review of the export of carbon in river water: fluxes and processes.
TL;DR: This review summarizes data on exports of carbon from a large number of temperate and boreal catchments in North America, Europe and New Zealand, finding a lack of information on the flux of particulate organic carbon and dissolved CO2 is highlighted.
Journal ArticleDOI
Rare earth elements in river waters
TL;DR: In this article, the authors measured the input to the oceans of rare earth elements (REE) in the dissolved and the suspended loads of rivers, and found that the dissolved loads in the five major rivers had relatively heavy-REE enrichments relative to the NASC and the suspension material, with the (La/Yb)N ratio of about 0.4.

The low-temperature geochemical cycle of iron: From continental fluxes to marine sediment deposition
Simon W. Poulton,Robert Raiswell +1 more
TL;DR: In this paper, a comparison of the globally-averaged compositions of riverine particulates and marine sediments reveals that the latter are depleted in FeHR, FePR and FeT but enriched in FeU.

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.

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
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.
Journal ArticleDOI
The removal of dissolved humic acids and iron during estuarine mixing
TL;DR: In this article, a small fraction of river dissolved organic matter is preferentially and rapidly flocculated during estuarine mixing and this fraction is the high molecular weight component of dissolved humic acids (0.45−0.1 μm filtered).
