Hf isotope ratio analysis using multi-collector inductively coupled plasma mass spectrometry: an evaluation of isobaric interference corrections
From measurements of Hf–Yb mixtures, we have found that the correction of isobaric interferences involving accepted Yb isotope ratios and reasonable estimates of mass bias result in a significantlyExpand
Evolution and Biogeography of Deep-Sea Vent and Seep Invertebrates
The recent evolution of many vent and seep invertebrate species suggests that Cenozoic tectonic history and oceanic circulation patterns have been important in defining contemporary biogeographic patterns. Expand
Application of the Ce anomaly as a paleoredox indicator: The ground rules
Much attention has been paid, in recent years, to the potential application of the Ce anomaly, measured in various marine phases, as a paleoceanographic indicator of widespread marine anoxia. In thisExpand
Deep, diverse and definitely different: unique attributes of the world's largest ecosystem
Abstract. The deep sea, the largest biome on Earth, has a series of characteristics that make this environment both distinct from other marine and land ecosystems and unique for the entire planet.Expand
The effect of plume processes on the Fe isotope composition of hydrothermally derived Fe in the deep ocean as inferred from the Rainbow vent site, Mid-Atlantic Ridge, 36°14′N
Abstract The Rainbow hydrothermal vent site, which is the largest known point source for dissolved Fe delivered to the deep North Atlantic ocean, has remained invariant in its Fe isotope compositionExpand
The distribution and stabilisation of dissolved Fe in deep-sea hydrothermal plumes
We have conducted a study of hydrothermal plumes overlying the Mid-Atlantic Ridge near 5° S to investigate whether there is a significant export flux of dissolved Fe from hydrothermal venting to theExpand
Hydrothermal scavenging of rare-earth elements in the ocean
SUSPENDED participate samples collected from the TAG hydrothermal vent field, at 26° N on the Mid-Atlantic Ridge, contain ˜10% of the total rare-earth element content (by volume) of ambient seaExpand
Redox cycling of rare earth elements in the suboxic zone of the Black Sea
REE cycling in the Black Sea occurs at the oxic/suboxic interface, not at the interface with anoxic waters as has been reported previously. REE cycling in the Black Sea is associated with the redoxExpand
An improved method for extracting marine sediment fractions and its application to Sr and Nd isotopic analysis
The radiogenic isotopic composition of both detrital and Fe–Mn fractions in marine sediments can be used in paleoceanography to infer changes of bottom-water circulation. We have examined variousExpand
Basin-scale transport of hydrothermal dissolved metals across the South Pacific Ocean
Complementary simulations with a global-scale ocean biogeochemical model suggest that the observed transport of hydrothermal dissolved iron requires some means of physicochemical stabilization and indicate that hydrothermally derived iron sustains a large fraction of Southern Ocean export production.
