Our paper on marine benthic Be fluxes came out @ScienceAdvances! We show benthic fluxes from ocean sediments, rather than riverine dissolved load, may dominate the oceanic 9Be budget, complicating the use of 10Be/9Be as a paleo-denudation tracer. OA link https://t.co/u6KvjLUlta

🌊Exciting partnership! ECNU, IMBeR, and SCOR signed a Trilateral MoU, marking the continuation of ECNU’s collaboration with IMBeR and SCOR to jointly advance marine science research and promote sustainable ocean development. @SCOR_Int @ECNUER

Marine Be isotopes have been utilized to date archives and reconstruct paleo-magnetism and continental denudation. We here modeled the global oceanic cycle of Be isotopes, with a detailed analysis of the effects of external inputs, scavenging, and circulation on seawater 10Be/9Be

Very interesting GEOTRACES session at @goldschmidt2023 today!
The room is packed!!

[Kai Deng @Geo_KDeng]

Great talk on all kinds of marine particles (especially Mn oxides)! And really enjoyed the event "Meet the Plenary Tuesday" with @PhoebeLam9

[GEOTRACES @geotraces]

Congratulations to Phoebe Lam who has just received the P. Gast Medal at @goldschmidt2023!

Talk: Marine particle geochemistry: influence on biogeochemical cycles in the ocean

[Kai Deng @Geo_KDeng]

Besides, there are many exciting talks in our session tomorrow! @April__Abbott will give an invited talk on the role of sediment composition on the benthic flux of neodymium!

Will present tomorrow morning at @goldschmidt2023 in the #GEOTRACES session (13cO1)! The presentation is about our recent paper on #benthic fluxes of #beryllium and its implications for #beryllium #isotopes as a continent #denudation proxy.

@isotope_Ral Indeed!😃

[Kai Deng @Geo_KDeng]

Thrilled to begin my new journey as a #Humboldt research fellow @AvHStiftung at @GFZ_Potsdam! Will explore the link between continent weatherability and metal isotopes in #basalt catchments. Exciting times ahead! 🤞😊

[Kai Deng @Geo_KDeng]

@April__Abbott Look forward to it!

4) At last, huge thanks to an amazing co-author team from Switzerland, Germany, the US, and China!🥳

3) The benthic flux provides a resolution to the oceanic 9Be imbalance, and could even be higher than the riverine dissolved load! A new model considering the benthic source is thus required to interpret paleo-records of Be isotopes (& other particle-reactive elements).
