A better insight into parameters that control particle flux in the ocean
Xiang and co-workers compiled full ocean-depth size-fractionated particle data from three recent U.S. GEOTRACES cruises.
Science Highlights
Some recent GEOTRACES science findings are reported below.
Assessment of deep-sea mining on Ocean health
Artigue and co-workers conducted a study to constrain how lithium and strontium from hydrothermal vents are dispersed in the ocean.
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.
Nickel bioactive role in the oceans assessed by its isotopes
Lemaitre and her colleagues realized the simultaneous analysis of the dissolved nickel isotopes and concentrations in the North Atlantic.
After the Mediterranean Sea one, don’t miss the Arctic present-day total mercury mass balance!
They provide an updated mass balance of the Arctic land and ocean mercury cycle.
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.
