Do you want to know more about iron and its isotopes? This review is for you!
Authors present a comprehensive review of iron and iron isotope sources, internal cycling, and sinks in the ocean.
Science Highlights
Some recent GEOTRACES science findings are reported below.
Actinium-227 distribution traces at least three processes in the North Atlantic Ocean
Le Roy and colleagues report an oceanic section of Actinium-227 in the North Atlantic Ocean.
Transient tracers, water mass ages and mixing time scales in the Arctic Ocean
Smith and colleagues determined iodine-129, chlorofluorocarbons and sulfur hexafluoride during three GEOTRACES cruises in the Arctic Ocean.
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…
Tracing dust deposition with aluminium and silicate at a resolution never reached before
Benaltabet and his colleagues propose a study of the dissolved aluminium and silicate fate in the Gulf of Aqaba (Red Sea).
Different fates of four poorly soluble trace elements in the Pacific Ocean
Zheng and co-authors present the full-depth distributions of aluminum, lead, manganese and copper in the western South Pacific.
Internal tides, energetic dynamical processes that generate particle nepheloids at different depths
In this study, Barbot and co-authors identified the sites where internal tides are responsible for sediment resuspension…
Greenland’s floating ice tongues, sources of dissolved lead to the Arctic
Using helium and neon as tracers for subglacial meltwater, Krisch and colleagues found that subglacial discharge is a source of dissolved lead.
Shelf sediments in the Benguela Upwelling System as a major source of trace metals to the shelf and eastern South Atlantic Ocean
Liu and her colleagues investigated dissolved trace metals distributions within the Benguela Upwelling System sampled from GEOTRACES GA08 cruise.
