This report collects the abstracts of the presentations given during the “iNEST-Young Researchers Workshop: Advancing in understanding the Gulf of Trieste coastal dynamics through interdisciplinary research”, which took place on 15 July 2025 at the Adriatico Guesthouse (ICTP, Trieste).The workshop was organised as part of the Interconnected Nord-Est Innovation Ecosystem (iNEST) project, with the aim of highlighting the contribution of young researchers to the study of the Gulf of Trieste. The event provided an opportunity to present the preliminary results from the three funded young researchers projects – NEREIDES, REDEFINE and IF-MA – and to share novel approaches to understanding the complex interactions between river and marine systems.The works presented covered a wide range of disciplines, including physical oceanography, biogeochemistry, data management and innovative modelling approaches, all with the common goal of improving our knowledge of the Gulf of Trieste and supporting the development of a Digital Twin of the Northern Adriatic Sea.This collection of abstracts reflects the diversity of perspectives and methods presented during the workshop and it aims to serve both as a reference for participants and as a basis for future collaborations within the iNEST community. This work was funded by the European Union - NextGenerationEU, in the framework of the iNEST - Interconnected Nord-Est Innovation Ecosystem (iNEST ECS00000043 – CUP F43C22000190006) - Project NEREIDES-Bando Giovani Ricercatori.

The report was developed as part of the activities carried out by Spoke 8, Research Topic RT1 (Biology of hydrosphere ecosystems), Task S3_RT1.1.3 (Filling knowledge gaps in observation).
