The oceanic chemistry of the rare-earth elements
TL;DR: Because of the unique chemical characteristics of the rare-earth elements (rees), they provide information as oceanic tracers of element source and reactivity as well as their interaction with the biogeochemical cycle.

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.

Chemostratigraphy of the Jurassic System: applications, limitations and implications for palaeoceanography
TL;DR: The use of one sedimentary component (marine organic carbon), one divalent transition metal substituted in carbonate (manganese), and two isotopic tracers: strontium-isotope ratios ( 87 Sr/ 86 Sr) and carbon-isotropic ratios (δ 13 C carb and δ 13C org ) in carbonates and in organic matter) has been used for the study of the Jurassic System as mentioned in this paper.

Radiogenic isotopes: tracers of past ocean circulation and erosional input
TL;DR: The radiogenic isotope composition of dissolved trace metals in the ocean represents a set of relatively new and not yet fully exploited tracers with a large potential for oceanographic and paleoceanographic research on timescales from the present back to at least 60 Ma.

Strong and deep Atlantic meridional overturning circulation during the last glacial cycle
Evelyn Böhm,Jörg Lippold,Marcus Gutjahr,Martin Frank,Patrick Blaser,Benny Antz,Jens Fohlmeister,Norbert Frank,Morten B. Andersen,Michael Deininger +9 more
TL;DR: It is shown that a deep and vigorous overturning circulation mode has persisted for most of the last glacial cycle, dominating ocean circulation in the Atlantic, whereas a shallower glacial mode with southern-sourced waters filling the deep western North Atlantic prevailed during glacial maxima.

A Sm-Nd isotopic study of atmospheric dusts and particulates from major river systems
TL;DR: In this paper, the average ratio of Sm/Nd is about 0.19 in the upper continental crust, and has remained so since the early Archean, thereby precluding the likelihood of major mafic-to-felsic or felsicto-mafic trends in the overall composition of the sedimentary mass through earth history.

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.
Journal ArticleDOI
Nd isotopic variations and petrogenetic models
TL;DR: In this article, the authors analyzed the geochemical properties of a chondritic reservoir with high Fe, high Fe basalt, Ti basalt and alkali basalts and compared the results with the present value of the source regions of the earth.
Journal ArticleDOI
Rare earth elements in the Pacific and Atlantic Oceans
TL;DR: The first profiles of rare earth elements in the Pacific Ocean were reported in this paper, showing that the distribution of the rare earth groups is consistent with two simultaneous processes: 1) cycling similar to that of opal and calcium carbonate 2) adsorptive scavenging by settling particles and possibly by uptake at ocean boundaries.
