What controls the barium distribution in the Arctic Ocean?
They synthesized what controls the barium distribution in the Arctic Ocean.
Radium-224 and radium-223: powerful chronometers to estimate the residence time of Amazon waters on the Brazilian continental shelf
In this study, radium is used as a tracer for the waters of the Amazon that mix with those of the Atlantic Ocean.
From Alaska to Tahiti, the distribution and bulk deposition fluxes of trace elements
A suite of trace element was measured in aerosols collected in the North and equatorial Pacific.
In situ detection of Particulate Inorganic Carbon using optical sensors
They have developed optical sensors for particulate inorganic carbon concentration.
When titanium is not always behaving as a lithogenic conservative tracer: an Amazon estuary story
They established the distribution of titanium in Amazon and Pará rivers and their related plume during the high discharge period.
Central Arctic fertilization by the Transpolar Drift
Their findings highlight the importance of the Transpolar Drift in delivering dissolved silica and iron to feed low diatom primary production in the central Arctic Ocean.
Dust deposition rates extracted from a data-assimilation model of the aluminium oceanic cycle
Xu and Weber developed a data-assimilation model of the aluminum oceanic cycle.
Intense benthic nepheloid layers in the Northwest Atlantic Ocean lead to unexpected distributions of dissolved and particulate thorium-230 and protactinium-231
Chen and colleagues explore the behaviour of thorium-230 and protactinium-231 in the benthic nepheloid layers…
