New algorithm unclogs major bottleneck in ocean geochemical and biogeochemical modelling
Numerical models are some of the principal tools for understanding the cycling of geochemical and biogeochemical tracers in the ocean…
Science Highlights
Some recent GEOTRACES science findings are reported below.
The tumultuous life of the Antarctic Circumpolar Current over 5,3 million years, including focus on the glacial-interglacial forcing!
Lamy and co-authors used sediment records from the pelagic central and remote South Pacific Ocean, to reconstruct the strength of the Antarctic Circumpolar Current and shifts of the Southern Ocean frontal system over the past roughly 5.3 Myr…
North-South radium-228 section in the Pacific Ocean
Moore and colleagues present results from radium-228 along the U.S. GEOTRACES Pacific Meridional Transect (GP15).
Strong lithogenic imprints in the Indian Ocean waters
Ueki and co-authors reported the first sectional distributions of zirconium, hafnium and niobium along a north-south track in the Indian Ocean.
The development of the modern Antarctic Circumpolar Current occurred much later than previously thought!
This study is challenging the belief that the onset of the Antarctic Circumpolar Current was solely triggered by the opening and deepening of Southern Ocean Gateways.
A dynamic iron cycle in Peru
Gu and colleagues explore the temporal variation of iron over 11 cruises along the Peruvian shelf.
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.
Aluminium, manganese, iron, cobalt, and lead display contrasting fate along north–south and east–west sections in the North Pacific Ocean
Chan et co-authors provide a comprehensive view of trace metal distribution in the subarctic Pacific Ocean.
Trans Polar Drift transport controls the dissolved copper-organic binding ligand distribution
Arnone and her colleagues report the concentrations and conditional stability constants of dissolved copper-binding ligands in the Arctic Ocean…
