Liu and colleagues show that rainfall augments some fluxes of trace metals from the Congo River.

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…
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.
Distributions, boundary inputs, and scavenging processes of trace metals in the East Sea (Japan Sea)
Seo and his colleagues show pronounced atmospheric and shelf inputs of trace elements in the Japan Sea.
Icebergs as sources of trace metals to the ocean: which impact?
Earth’s Ice Sheets are known to release significant quantities of lithogenic particles into the ocean every year, but how does this material affect trace metal availability in the ocean?
Scavenging differentiates the distribution of cadmium, nickel, zinc and copper in the North Pacific Ocean
Zheng and co-authors observed sectional distributions of cadmium, nickel, zinc, and copper in the North Pacific Ocean during three GEOTRACES related cruises…
Surprising conservativity of trace metals along a costal embayment salinity gradient
Chen and co-workers analyzed an array of trace metals together with Rare Earth Elements in a salinity gradient in the Jinhae Bay, the largest semi-enclosed bay in South Korea…
Pros and cons of nine bioactive trace elements as tracers of modern and paleo-productivity
Horner and co-authors assess whether nine bioactive trace metals and their isotopes can be used as paleo-productivity proxies.
Spatial and temporal variability of bioactive trace metals, speciation and organic metal-binding ligands in the eastern Gulf of Mexico
Mellett and Buck present the concentrations of bioactive trace metals (Fe, Cu, Mn, Zn, Co, Ni, Cd, and Pb), Fe-and Cu-binding organic ligands, and electroactive Fe-binding humic substances in the eastern Gulf of Mexico.
Constraining Oceanic Copper Cycling through Artificial Intelligence and Ocean Circulation Inverse Model
Using available observations of dissolved copper, artificial neural networks, and an ocean circulation inverse model, authors calculated a global estimate of the 3-dimensional distribution and cycling of dissolved copper in the ocean.
Estuary solid loads and solid-solution exchanges yield considerable dissolved trace metal enrichments
Based on a thorough investigation of water and suspended sediment samples collected over two years and a six seasons, Samanta and Dalai (2018, see reference below) show that the annual […]
A new method for simultaneous analysis of nickel, copper and zinc isotopes in seawater
Takano and co-workers (2017, see reference below) have developed a new method to determine nickel (Ni), copper (Cu) and zinc (Zn) isotopes in seawater. This method is very simple and […]
What controls the copper isotopic composition in oceanic waters?
Takano and co-workers (2014, see reference below) strongly suggest that the isotopic composition of dissolved copper (δ65Cu) in surface seawater is mainly controlled by supply from rivers, the atmosphere and […]
Organic copper complexation may stabilise seawater stable copper isotopic composition
Three deep-sea profiles were produced for the analysis of copper (Cu) concentration, along a transect covering very different biogeochemical regions: the oligotrophic North Tasman Sea (30ºS), the Tasman Front (40°S) […]
Undocumented cadmium, zinc and copper sink in oxygen minimum zones
Cadmium (Cd) is a micronutrient for marine algae and has a marine distribution similar to the macronutrients nitrate and phosphate. The use of sedimentary microfossil records of Cd, thus, allow […]
Copper and zinc oceanic mass balance revisited
Little and co-workers (2014; see reference below) propose an update of the oceanic copper (Cu) and zinc (Zn) mass balance, with the original approach that takes into account the hitherto […]
