The Amazonian mangrove systems accumulate and release dissolved neodymium and hafnium to the oceans
Xu and colleagues investigated the concentrations of rare earth elements in the Amazonian mangrove.
Trace metal fluxes of cadmium, copper, lead and zinc from the Congo River into the South Atlantic Ocean are supplemented by atmospheric inputs
Liu and colleagues show that rainfall augments some fluxes of trace metals from the Congo River.
Overlooked riverine contributions of dissolved neodymium and hafnium to the Amazon estuary and oceans
Xu and colleagues investigated the isotopic composition of dissolved neodymium and hafnium along the entire salinity gradient of the Amazon estuary.
Terrestrial iron inputs and reverse weathering in the Amazon mouth
Understanding the key processes that condition the net input of chemical species to the ocean is an important challenge…
North African dust is an important (but not dominant) source of iron to the Gulf of Mexico
Hayes and colleagues have combined data to estimate how important North African dust could be as a source of iron to the Gulf of Mexico.
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.
The power of combining geochemical tracer data with direct current measurements
Learn about new discoveries done combining seawater Rare Earth Elements concentrations and direct physical oceanographic observations
Land inputs in the Arctic transported up to the North Pole
A new study found that freshwater runoff from rivers and continental shelf sediments are bringing significant quantities of carbon and trace elements into parts of the Arctic Ocean
Unprecedented iron delivery from the Congo River margin to the South Atlantic Gyre
Radium isotopes are used to demonstrate that make the Congo the most significant riverine source of iron to the South Atlantic.
Solute-particle interactions and the enhanced dissolved barium flux from the Ganga River estuary
Dissolved and particulate barium (Ba) were investigated in samples that were collected in six periods of contrasting water discharge over two years (2012 and 2013) by Saumik and Dalai (2016, […]
