Welcome to the inaugural edition of our EuroMarine Researchers in the Spotlight series, where we engage in captivating conversations with prominent researchers within our network.

Jellyfish, encompassing various species of gelatinous zooplankton, play crucial roles in marine ecosystems, providing ecosystem services often overlooked, including carbon cycling, habitat provision, and compounds with biotechnological applications. We interviewed Isabella D´Ambra from SZN and Cornelia Jaspers from DTU Aqua on their experiences leading the JELLY-NEXT Foresight Workshop, which aimed at bridging gaps through collaboration, data sharing, and engagement with research infrastructures (RIs) to enhance monitoring and data collection efforts.

Despite their importance, understanding jellyfish mass appearances (blooms and outbreaks) and their impacts on human activities remain limited due to scattered data, methodological differences, and a lack of standardized protocols.

Initiatives like the JEDI database and JellyWatch have attempted to gather data, but issues persist, including the mismatch between molecular and morphological data and the lack of consisent abundance recordings.

To address these challenges, the proposal suggests forming a working group (WG JELLY-NEXT) composed of experts from various disciplines to assess current knowledge, identify research priorities, and develop strategies.

The WG aims to bridge gaps through collaboration, data sharing, and engagement with research infrastructures (RIs) to enhance monitoring and data collection efforts. Overall, the proposal emphasizes the need for concerted efforts to advance jellyfish research, address urgent issues, and support the next generation of researchers.
