Geochemistry offers unique solutions to global and local challenges. However, translating this promise into practice necessitates an open, diverse, equitable and inclusive scientific model. This cross-cutting theme links sessions and abstracts, submitted to any of the other themes, that explore various aspects of using geochemistry to inform the public and policy.

⏲️ Registration and abstract submission for the 5th workshop on waves and wave-coupled processes will close in 2 weeks. If you plan to join us in Reading (UK) on 10–12 April and/or submit an abstract, don’t forget to submit the forms before 1 March. The workshop will aim to cover the following topics: Dynamics of ocean waves Air-sea fluxes and atmospheric wave boundary layer Wave influences in the upper ocean Wave-sea-ice interactions Wave-current interactions Wave-coupled processes in extreme conditions Wave-coupled effects in gas transfer and aerosol production Wave-coupled role in ocean biogeochemistry, and other air-sea interface processes Coupling strategies For more information and to access the registration and abstract submission forms ➡️ https://lnkd.in/gAAWUsus #5thWSwaves

The first method from my PhD was published in April! If you fancy reading it, here's the link: https://lnkd.in/e6zGyKkz This method provides an accurate and more time efficient way to isolate different sediment grain size fractions which are already sieved <63 µm for further work such as radiogenic isotopes or clumped isotopes. We provide three grain size examples (<2 µm, 2-10 µm and 10-63 µm) using both lithogenic or biogenic (carbonate rich) sediment samples. We hope this separation method will provide a more standardised way of comparing radiogenic isotopes between studies (watch this space!)

New article just released in Earth and Planetary Science Letters, examining the behaviour of iron and chromium isotopes in the smoke-like plumes from two hydrothermal vents along the Mid-Atlantic Ridge! Our paper uses some of samples from the #GEOTRACES research program and includes my data on particle elemental composition and the subsequent iron and chromium isotopic composition of the particles I digested as part of my #PhD research! Our data helps us to better understand the dynamic behaviour of different elements in our oceans, constrain their global balance, and demonstrates the power of isotopic techniques in revealing the secrets of the natural world. #science #oceanography #chemistry https://lnkd.in/eHppgs4f
