New software enables global ocean biogeochemical modeling in Python
The newly designed tmm4py software makes biogeochemical modelling more widely accessible.
Science Highlights
Some recent GEOTRACES science findings are reported below.
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.
Rare Earth and neodymium isotope cycles in the abyssal Pacific Ocean are shaking up the paradigm established for particle reactive tracers
Du and colleagues demonstrate the importance of the abyssal sediment source in the control of the trace element and isotopes marine distribution.
Anthropogenic iron impact on the surface productivity in the Pacific Transition Zone
Hawco and colleagues investigated the influence of industrial emissions on oceanic iron supply and its ecological consequences in the North Pacific.
Trace metal effluxes from Peruvian shelf sediments
Liu and co-authors compared four methods to estimate dissolved iron fluxes from Peruvian shelf sediments, revealing large variability.
Coupling copper and neodymium data highlights the importance of the margin sources for the copper oceanic cycle
Lemaitre and co-workers analysed the dissolved concentrations and isotopes along the GEOVIDE (GA01) section in the North Atlantic Ocean.
High levels of anthropogenic lead in the Indian Ocean
Yadav and her colleagues provide comprehensive insights into the distribution and sources of dissolved lead in the Indian Ocean.
Elevated methylmercury level in Arctic rain and aerosol linked to oceanic dimethylmercury emissions
He and colleagues highlight a previously underappreciated pathway of mercury transport, underscoring its significance to human health.
