From: Ery Hughes < [ mailto:ery.hughes@ucl.ac.uk | ery.hughes@ucl.ac.uk ] > If you are attending Goldschmidt 2026 in Montreal (or even if you’re not…), consider signing up to our full‑day workshop dedicated to advancing the science and practice of volcanic gas measurements and modelling - Modelling volatile behaviours in magmas - it is free and running both in-person in Montreal and virtually! We have space for 50 participants in-person so first in, first served! If you’re not in Montreal or we’ve reached our in-person limit, you can join us online. Please sign up using this link: [ https://forms.gle/dQHS3qWW2dfvJH3dA | https://forms.gle/dQHS3qWW2dfvJH3dA ] The workshop will run from 9:00 am until 4:00 pm EST on Sunday 12th July 2026 and will be housed at McGill University (more details to come), leading seamlessly into the Goldschmidt Icebreaker at 5:00 pm The workshop will begin with an overview of natural volcanic degassing processes and the current state of in situ and satellite‑based monitoring techniques. A series of structured presentations will provide insights into case studies from natural volcanic systems. Topics will include gas measurements during monitoring, experimental approaches (including melt and fluid inclusion analyses), sulfur partitioning, Raman‑based SO₂/CO₂ speciation, and current challenges in calibrating and applying numerical models. Participants will also engage in guided group exercises run through VICTOR designed to reproduce benchmarking results, compare methodological approaches, and identify priorities for improving data quality and model performance. Outcomes from these activities will contribute to an updated Workshop White Paper, helping to shape collective standards and future directions. All researchers, students, and professionals engaged in volcanic gas studies are encouraged to attend this collaborative event. Cost: Free!
