Dear MARMAM community, The first edition of BioMonWeek, led by Biodiversa+ and co-organized with GBIF, BioAgora, MARCO-BOLO and the Alliance for Nature, is taking place in Montpellier, 4-8 May 2026. Biodiversity Monitoring Week (BioMonWeek) is a new European conference aiming to mirror the GEOBON conference in alternate years. This inaugural edition marks a launch guided by a vision to deliver an impactful biannual format. The event will bring together science, policy, and business communities to exchange monitoring knowledge, build networks, and drive tangible societal impact to help reverse the global biodiversity crisis. The programme will feature plenary keynotes and panels, contributed sessions and workshops, focusing on 9 different themes, one of them related to Marine Monitoring: Observing Ocean ecosystems. Within this theme, there is a specific session on "Marine mammal monitoring programmes to support management", currently accepting contributions. Other sessions may be of interest, so please take a look at the programme and further details on the event, here: https://2026.biomonweek.eu/page/home/ Note that, at this stage, your pre-registration and abstract submission will not be considered 100% commitment.
