Preprint: Scientific mediation as a social technology in public research institutions: insights from a decade of action research in a geological survey

This preprint presents a Practice Insight submitted to the Journal of Science Communication (JCOM) on 16 March 2026. The paper proposes scientific mediation as an epistemological construct and social technology grounded in a decade of action research (2016–2026) within the Geological Survey of Brazil. It analyses how a geoscientist-led mediation practice evolved from the VisualiGEO experimental channel into the Geoscience Audiovisual method and, later, into the institutionalisation of Geoscientific Mediation as a finalistic line of action.\n\n> The manuscript is based on three main sets of evidence: institutional documentation related to the internalisation of scientific mediation in SGB; historical usage data from the VisualiGEO YouTube channel; and usage data from audiovisual training series hosted on Vimeo. The article discusses the operating conditions, limits, transferability, and scalability of scientific mediation as a practice relevant to public research institutions internationally.\n\n> This file is the author’s submitted manuscript version (preprint), not the publisher’s Version of Record.
