Lead isotopes, reversible scavenging and ventilation processes in the South Atlantic Ocean
Olivelli and co-authors present seawater lead concentrations and lead isotopes for 10 depth profiles collected in the South Atlantic Ocean.
Scavenging
Surprise in the Gulf of Aqaba: intense dust inputs are not a source of trace metals to seawater!
Benaltabet and his colleagues present a 2-year time series of several trace metal concentration profiles sampled at a daily resolution.
Lead isotopes allow tracing the processes injecting of anthropogenic lead in deep waters
This work follows the penetration of anthropogenic lead (traced using its isotopic signatures) into the pristine deep Pacific Ocean.
Pulling back the veil on reversible scavenging of lead
This work further contains the role that reversible scavenging may play in the cycling of lead in the ocean, an ever-evolving global experiment where lead contamination can be tracked in real-time.
Extremely high radioactive levels in the manganese nodules
Volz and co-authors demonstrate that radioisotopes in the manganese nodules mostly exceed exempt activity levels…
Distributions, boundary inputs, and scavenging processes of trace metals in the East Sea (Japan Sea)
Seo and his colleagues show pronounced atmospheric and shelf inputs of trace elements in the Japan Sea.
Scavenging differentiates the distribution of cadmium, nickel, zinc and copper in the North Pacific Ocean
Zheng and co-authors observed sectional distributions of cadmium, nickel, zinc, and copper in the North Pacific Ocean during three GEOTRACES related cruises…
When lateral advective transport explains between 80 and 100% of the dissolved aluminium distribution
The results evidence that the effect of advection cannot be neglected in areas where a conjunction of significant horizontal dissolved aluminium gradients and significant horizontal currents is found.
Adding external sources allow a better simulation of the oceanic rare earth elements cycles
Oka and colleagues demonstrate that the global distribution of REE can be reproduced by considering the internal cycle associated with reversible scavenging and external REEs inputs around continental regions.
Isopycnal mixing controls protactinium and thorium distributions in the Pacific Southern Ocean
Pavia and co-workers determined the physical and chemical speciation as well as the vertical distribution of Protactinium-231 and Thorium-230 at 12 stations across the Southern Pacific Antarctic Circumpolar Current…
Time series thorium-230 data reveal scavenging intensification over the last 15 years in the Arctic Ocean
Authors demonstrate that the later hypothesis is likely explaining thorium-230-depletion in intermediate layers of the Amundsen basin.
A new model simulates the speciation and dispersion of hydrothermal iron
Roshan and collaborators present new observations of dissolved iron and its physical speciation in the South Pacific
Tracing scavenging intensity with the original coupling between scandium, yttrium and lanthanum in surface waters
The first basin-wide surface scandium (Sc), yttrium (Y) and lanthanum (La) concentration data in a section across the North Atlantic subtropical gyre (2011 GEOTRACES GA03) is reported by Till and […]
