SUMMARY:GEOTRACES Online Seminar Series - #1 Data synthesis\, modelling & integration
DESCRIPTION:The GEOTRACES Online Seminar Series is an initiative led by the Early Career Scientist (ECS) committee\, held on a monthly basis. It aims to foster scientific exchange across the GEOTRACES community and beyond by bringing together senior scientists and early-career researchers around shared themes in trace element and isotope biogeochemistry.Seminar format:Each seminar will focus on one coherent topic and feature two connected talks:– A senior scientist providing synthesis\, context\, and big-picture framing– An early-career scientist presenting new data\, methods\, or emerging perspectives \n\n\n\nSchedule:\n\n\n\n\n\nThe series will run monthly from April to November 2026 (with a break in July)\, with seminars planned for the last Tuesday of each month. Plus\, an end-year special seminar around mid-December. \n\n\n\nSeminars will be held at either 09:00 CET/CEST or 15:00 CET/CEST\, depending on the speakers’ locations\, to facilitate participation across different regions. Each seminar will last about one hour. \n\n\n\n \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nPlatform: Zoom\n\n\n\nA single recurring link will be used for all seminars: click here to access the seminar.If needed\, you can also join manually using: Meeting ID: 636 5773 3493 / Passcode: 651026 \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nSEMINAR #1 – APRIL 2026\n\n\n\n\n\n\n\nTime: April 28 @ 15:00 CESTModerator: Dr. Anh Pham (University of California\, Los Angeles)Seminar access (Zoom): Zoom Link / Meeting ID: 636 5773 3493 / Passcode: 651026\n\n\n\n\n\n\n\n\n\nBringing it all together: using models to build process understandingDr. Gregory De Souza (ETH Zurich\, Switzerland) – Senior Scientist \n\n\n\nAbstract: Two decades of GEOTRACES observations provide us with a wealth of TEI data at a range of spatial scales. Inferring controlling processes from these data requires an understanding of how sources and sinks — whether in the open ocean or at its margins — interact with ocean circulation to produce observed distributions of dissolved species. In this talk\, I will give an overview of the diversity of approaches that have used conceptual and/or numerical models to synthesize observational data into an understanding of TEI cycling in the sea and at its interfaces. \n\n\n\n\n\nSenior scientistDr. Gregory De SouzaETH Zurich\, Switzerland\n\n\n\n\n\n\n\n\n\n\n\nMapping ocean trace metal distributions: A global data-driven view of lead and its isotopesDr. Arianna Olivelli (Flanders Marine Institute\, Belgium) – Early Career Scientist \n\n\n\nAbstract: Despite the rapid growth of GEOTRACES observations\, resolving large-scale distributions of trace metals remains challenging due to their sparse and heterogeneous coverage. In recent years\, machine learning (ML) techniques have offered new opportunities to advance data-driven oceanographic research at global and regional scales. In this talk\, I will present my work to develop the first global maps of lead (Pb) concentrations and isotope compositions from surface to depth using the tree-ensemble algorithm XGBoost and explainable ML tools. These maps provide an observation-based view of Pb distributions and variability that is difficult to achieve from measurements alone. I will discuss key methodological choices\, lessons learned\, and potential future applications of these maps. Additionally\, I will explore the use of different ML approaches for the synthesis and integration of in situ observations within the wider GEOTRACES context. \n\n\n\n\n\nEarly Career ScientistDr. Arianna OlivelliFlanders Marine Institute\, Belgium\n\n\n\n\n\n\n\n\n\nUpcoming seminars:\n\n\n\nMay 26\, 2026 @ 15:00 CESTTopic: Trace metal input in polar environmentsSpeakers: Jon Hawkings (University of Pennsylvania) & Laramie Jensen (Columbia University) \n\n\n\nJune 30\, 2026 @ 15:00 CESTTopic: Atmospheric aerosol deposition to the global oceanSpeakers: Clifton Buck (University of Georgia) & Prema Piyusha Panda (Stellenbosch University) \n\n\n\n\n\n\n\nFurther seminars will be announced in due course.

SUMMARY:EGU General Assembly 2026
DESCRIPTION:Vienna\, Austria & Onlinehttps://www.egu26.eu/\n\n\n\nThe EGU General Assembly 2026 brings together geoscientists from all over the world to one meeting covering all disciplines of the Earth\, planetary\, and space sciences. The EGU aims to provide a forum where scientists\, especially early career researchers\, can present their work and discuss their ideas with experts in all fields of geoscience. \n\n\n\n\n\n\n\nDeadline for abstract submission is 15 January 2026\, 13:00 CET. \n\n\n\n\n\n\n\nGEOTRACES relevant session:\n\n\n\n\n\n\n\nChemical Processes in Coastal Oceans: Natural and Anthropogenic impacts on the biogeochemical processes \n\n\n\nConvener: Aridane González GonzálezCo-conveners: David González-Santana\, Melchor Gonzalez-Davila\, J. Magdalena Santana-Casiano \n\n\n\nCoastal oceans are dynamic interfaces between land and sea\, playing a critical role in global biogeochemical cycles with a high impact on socio-economic activities and social developments. The dynamic and physical processes as well as the human activities that take place in coastal areas make them natural laboratories to improve our knowledge about several biogeochemical interactions. In addition\, these regions are affected by both natural and anthropogenic factors such as coastal acidification\, organic matter\, nutrients\, and pollution\, among others. All these factors have impacts on the natural cycles and the magnitude of these impacts should be studied and understood in order to propose solutions to the decision makers that could help to know\, understand\, take decisions\, and protect or regulate the coastal environments. \n\n\n\nThis session aims to bring together researchers from diverse fields to discuss the latest findings on the biogeochemical processes occurring in coastal oceans\, improve our knowledge\, identify impacts\, and propose solutions in terms of coastal management and blue economy. We welcome research studies that focus on both natural and anthropogenic processes that are affecting the biogeochemical cycles in coastal waters\, trace metal chemistry\, CO2 system\, ocean acidification\, ocean alkalinization\, nutrient cycle\, organic matter\, CO2 sequestration\, blue carbon\, etc. \n\n\n\nTo submit an abstract please follow the instructions available here: https://www.egu26.eu/authors/how-to-submit.html
