iNEST-YR_REDEFINE project_dataset

The dataset collects the data produced during the activities of the REDEFINE (RivEr DischargEs in the GulF of TrIeste: a coNtribution to the improvEment of the digital twin of the northern Adriatic Sea) project. Monthly sampling was carried out from October 2024 to June 2025 under different hydrologic conditions (dry and flood periods) to investigate the contribution of the main rivers of Friuli Venezia Giulia (Italy), namely Isonzo, Timavo and Tagliamento, to the Gulf of Trieste, the northernmost basin of the Northern Adriatic Sea. Sampling stations were located in proximity of river mouths, upstream of the saltwedge to avoid the potential influence of seawater, with the aim of providing a biogeochemical characterisation of these rivers in terms of nutrients, carbonate system parameters and organic matter loading. In addition, the REDEFINE project aims to quantify the role of these rivers as sources of microbial pollution, with particular focus on antibiotic-resistant bacteria. This study was funded by the European Union - NextGenerationEU, in the framework of the iNEST - Interconnected Nord-Est Innovation Ecosystem (iNEST ECS00000043 – CUP F43C22000190006) - Project REDEFINE-Bando Giovani Ricercatori.

The dataset was developed as part of the activities carried out by Spoke 8, RT1 (Biology of hydrosphere ecosystems), Task S8_RT1.3.1 (Biological and biogeochemical data integration for local blue carbon managing).
