Virtual Frontiers in Earth Magnetism: The legacy of MagNetZ webinar series

The MagNetZ (Magnetic Network on Zoom) webinar series stands as a cornerstone for geomagnetism research, hosting online seminars since the early 2020. Launched amid COVID-19 constraints, MagNetZ are convened by a team of scientists to give visibility to scientific work of both leading scientists and early career researchers, to foster virtual collaboration, overcoming geographical limits for students and professionals alike. It promotes open science sharing, with broad appeal evidenced by international viewership and institutional ties. The presentations typically began with a short talk, followed by interactive Q&A space, which are both recorded, post-edited and published on YouTube (https://www.youtube.com/@MagNetZ) in a continuously growing archive of recorded content. These webinars are also uploaded to the EarthRef.org Digital Archive (ERDA), development and maintained by the EarthRef.org Database Team and can be cited. Thus far, more than 80 webinars are available for viewing. MagNetZ also supports for national meetings, such as the UK-based annual Magnetic Interactions meeting, offering them the platform to view the recordings of three meetings so far. The webinars provide in-depth discussions on paleo- and rock-magnetism and geomagnetic modeling, with topics spanning from geo- and planetary magnetic field dynamics to mineral properties studies for paleoclimatic reconstructions, from paleomagnetic data for geodynamic applications to archaeomagnetism, and more. The core features of MagNetZ are to ensure accessibility for all genders, all career stages and geographical distributions, enhancing community networks, and serving as an educational hub for magnetic data in tectonics and climate studies. Its YouTube platform ensures enduring access, sparking collaborations and awareness.
