An original approach to assess the particulate trace metal concentrations in seawater
Sohrin and co-workers propose defining particulate trace metal as the difference between total dissolvable and dissolved metals after a long storage of filtered and unfiltered acidified seawater.
Constraining aerosol deposition over the global ocean by the cosmogenic beryllium-7
He and co-workers propose a global estimate of aerosol deposition onto the ocean using the cosmogenic radionuclide beryllium-7.
Oceanic lead concentrations and isotopes mapped using explainable machine learning
Using three machine learning models, Olivelli and her colleagues generated global climatologies of lead concentrations and isotopes…
Dissolved nickel sources: transformation and sinks in the Arabian Sea
Malla and co-authors present an extensive study of the distribution of dissolved nickel in the Arabian Sea.
Linking cadmium cycling to phosphate dynamics in the Indian Ocean: Evidence from GEOTRACES transects
Mishra and Singh determined cadmium and phosphate concentrations along 34 complete vertical profiles in the Indian Ocean.
New software enables global ocean biogeochemical modeling in Python
The newly designed tmm4py software makes biogeochemical modelling more widely accessible.
Aerosol dissolution and iron isotope fractionation during atmospheric transport
Camin and co-authors present the iron concentrations and isotopic compositions of aerosols in previously undocumented areas of the Pacific Ocean.
Paradoxical influence of hydrothermal methylmercury on local ecosystems
Torres Rodríguez and her colleagues investigate hydrothermal mercury inputs at the Tonga volcanic arc and their impact on local surface ocean ecosystems.
