SUMMARY:Goldschmidt 2026
DESCRIPTION:Montréal\, CanadaWebsite: https://conf.goldschmidt.info/goldschmidt/2026/goldschmidt/2026/meetingapp.cgi \n\n\n\nSubmit an abstract to the GEOTRACES sessions by 26 February 2026! \n\n\n\n\n\n**GEOTRACES and GEOTRACES related sessions\n\n\n\n12c – The Role of Boundaries Across Scales in Shaping Marine Trace Element Distributionshttps://conf.goldschmidt.info/goldschmidt/2026/goldschmidt/2026/meetingapp.cgi/Session/8629Trace elements and isotopes (TEIs) play essential roles in the ocean\, serving not only as micronutrients\, but useful tools for better understanding marine biogeochemistry. Their distributions are strongly influenced by boundaries – regions where physical\, chemical\, and biological gradients intersect to control redox states\, speciation\, and particle reactivity. This boundary concept encompasses large-scale interfaces (e.g. atmosphere-ocean\, seafloor-ocean\, land-ocean)\, and biogeochemical gradients\, including redox fronts\, Oxygen Minimum Zone (OMZ) – oxygenated transitions\, particle-seawater microenvironments\, and organism-associated microscale habitats (e.g.\, phycospheres\, benthic ecosystems)\, where intense exchange is mediated by chemical gradients and biological activity. At large-scale ocean interfaces\, inputs from natural and anthropogenic pathways\, rapid transformations (oxidation\, complexation\, adsorption)\, and burial occur\, thereby modulating oceanic TEI residence times. Within the water column\, sharp redox boundaries (e.g.\, at OMZs) regulate the solubility\, mobility\, and bioavailability of several TEIs (e.g.\, Fe\, Co). At the microscale\, particle surfaces and organic exudates define reactive microenvironments that control adsorption-desorption dynamics and trace metal speciation. Additionally\, the boundary between seawater and microorganism cells control metabolic processes and the internal cycle of TEIs. Recognizing this spectrum of boundaries highlights the interconnected pathways shaping TEI distributions across spatial scales\, helping to disentangle the importance of bottom-up versus top-down controls. Integrating processes from global interfaces to microscale gradients is thus essential for predicting how marine TEI cycling responds to climate change and anthropogenic perturbations. This session welcomes field observations\, laboratory experiments\, and modelling studies to gain further understanding on how different ocean “boundaries” control TEI distributions. \n\n\n\nConveners:Zhouling Zhang\, GEOMAR Helmholtz Centre for Ocean Research KielNolwenn Lemaitre\, Laboratoire d’Etudes en Géophysique et Oceanographie SpatialesRyan Cloete\, Stellenbosch UniversityAnh Le-Duy Pham\, University of California\, Los AngelesWen-Hsuan Liao\, National Cheng Kung University \n\n\n\n\n\n\n\n\n\n12j – Applications of naturally-occurring radioactive isotopes and constant flux proxies in seawater and marine sedimentshttps://conf.goldschmidt.info/goldschmidt/2026/goldschmidt/2026/meetingapp.cgi/Session/8897Naturally occurring radioisotopes and constant flux proxies have revolutionized our ability to quantify and reconstruct vertical particle settling and sediment deposition rates across a variety of modern and past oceanographic conditions. These geochemical tracers\, including U-series isotopes\, extraterrestrial helium-3\, meteoric beryllium-10\, and other isotopes with predictable production rates or input functions\, have thus enabled refined investigation into dynamic processes such as aerosol deposition\, continental input\, ocean circulation strength\, water mass changes\, hydrothermal metal fluxes\, biologic productivity and carbon export. Yet\, as constant flux proxies become more widely measured\, fundamental questions remain regarding when\, where\, and how the mechanics of each proxy system may or may not work as assumed and what information can be inferred when distinct proxies yield disparate results.This session invites observational and modeling contributions regarding recent applications\, insights\, and identified complications of naturally occurring radioisotopes and constant flux proxies applied in modern or paleoceanographic environments. \n\n\n\nConveners:Kassandra Costa\, Woods Hole Oceanographic InstitutionJennifer L Middleton\, Columbia UniversityFrank Pavia\, University of WashingtonKai Deng\, Tongji University \n\n\n\n\n\n\n\n09k – Integrating Biological and Geochemical Perspectives on Trace Metal(loid) Transformations Across Ecosystemshttps://conf.goldschmidt.info/goldschmidt/2026/meetingapp.cgi/Session/9054The biogeochemical cycling of trace metal(loid)s in both terrestrial and aquatic environments plays a central role in regulating ecosystem productivity\, elemental speciation\, and environmental health. Interactions among microbes\, minerals\, and dissolved species control the transformation\, bioavailability\, and isotopic signatures of key trace elements\, influencing complex biogeochemical feedbacks from local to global scales. Importantly\, trace metal(loid) transformations are tightly coupled to the cycling of carbon\, sulfur\, and other nutrients\, linking redox dynamics and microbial metabolism/detoxification processes to broader ecosystem function. This session unites studies that bridge biological and geochemical perspectives on trace metal(loid) cycling across redox gradients and physical scales—from laboratory experiments to field observations and modeling. We invite contributions examining mineral dissolution and precipitation\, redox transformations\, the formation of reactive organo-mineral complexes\, and methylation–demethylation reactions with a focus on elements including\, but not limited to\, mercury\, uranium\, arsenic\, selenium\, manganese\, and iron. We particularly welcome approaches integrating isotopic\, spectroscopic\, imaging\, -omics\, biosensor\, and modeling techniques to advance molecular understanding of trace element dynamics. By linking microbial and geochemical perspectives\, this session aims to provide new mechanistic insights into the speciation and environmental fate of trace metal(loid)s in societally important ecosystems including marine waters\, groundwater aquifers\, agricultural soils (such as rice paddies)\, and mining-impacted environments. \n\n\n\nConveners:Matthew Reid\, Cornell UniversityTim M.

SUMMARY:XMAS2027
DESCRIPTION:There will be two GEOTRACES related sessions/workshops at the forthcoming XMAS2027 meeting\, January 12 to 15\, 2027\, Xiamen (China). Abstracts can be submitted until 30 June 2026. Further details are available on the conference webpage: https://mel-xmas.net/index.html \n\n\n\n\n\n\n\nTrace metal biogeochemical cycles in the ocean (session) \n\n\n\nThe international GEOTRACES program and the development of trace metal clean analysis techniques has led to a revolution in our understanding of marine trace metal dynamics. The sources\, sinks and speciation of trace metals have been subject to intense study for several decades revealing the important roles of shelf sediments\, atmospheric deposition\, hydrothermal vents and the cryosphere as trace metal sources. Bioessential roles for micronutrients including iron\, manganese\, and cobalt in primary metabolism are well established. The importance of different biogenic\, authigenic and lithogenic particulate phases for controlling metal distributions is increasingly recognized. Unfortunately\, anthropogenic pollutants such as lead and mercury remain pervasive\, and climatic shifts in ocean temperature\, oxygen and pH are increasingly recognized as drivers of changing trace metal dynamics. Key questions in the context of climate change are how these physical drivers\, combined with changing source dynamics\, will affect the bioaccessibility of metals to marine biota. Understanding the role of trace metals in biogeochemical cycles is important to constrain the effects of climate change on the past\, present and future ocean system\, and to fully comprehend the implications of proposed ocean intervention schemes such as iron fertilization. We encourage submissions from interdisciplinary teams focusing on the sources\, sinks\, speciation and biological utilization of trace metal in marine systems worldwide. Studies that combine multiple methodological approaches or inter-regional comparisons to understand trace metal dynamics are especially welcomed. \n\n\n\nConveners \n\n\n\nRuifang Xie\, Shanghai Jiao Tong UniversityMark Moore\, University of SouthamptonLaramie Jensen\, Columbia UniversityMark Hopwood\, Southern University of Science and Technology \n\n\n\n\n\n\n\nA GEOTRACES synthesis workshop: Building data outcomes for the Pacific Ocean and its marginal seas (workshop) \n\n\n\nThe international GEOTRACES program has generated a wealth of knowledge on the biogeochemical cycles of trace elements and their isotopes in the ocean. With this growing body of observations\, there is a compelling opportunity to move toward synthesizing GEOTRACES data and draw broader insights into the role of metal dynamics in ocean biogeochemistry\, for example through the GEOTRACES Intermediate Data Product 2025 (IDP 2025). Here\, we take the Pacific Ocean and its marginal seas as a focus region\, offering diverse biogeochemical regimes and dataset with full potential to be realized through coordinated synthesis. To achieve this\, the workshop will feature invited talks in an extended format\, drawing on perspectives from field and laboratory observations and modeling to concrete proposals for synthesis outputs. Open discussion sessions and opportunities for networking will further support the collaborative exchange needed to turn this collective expertise into lasting scientific impact. \n\n\n\nYuping Guo\, GEOMAR Helmholtz Centre for Ocean Research KielZanna Chase\, The University of TasmaniaYihua Cai\, Xiamen UniversityTe Liu\, University of Southampton
