The Black Sea Physical Analysis and Forecasting System (BSFS) operates within the Monitoring Centre (BLK-MFC) as part of Copernicus Marine Service (CMEMS). Here we present ongoing research development activities for future generations BSFS. current system has 1/40-degree horizontal grid NEMO ocean model featuring 121 vertical levels. Significant enhancements encompass integration biharmonic viscosity instead traditional Laplacian constant viscosity. This adaptation effectively mitigates small-scale noise, thereby elevating accuracy in representing mesoscale eddies. A notable advancement includes implementation a two-way nested domain surrounding Bosphorus Strait, employing NEMO-AGRIF mesh refinement algorithm. newly constructed high-resolution Strait 1/200-degree resolution, facilitating much better resolution strait's bathymetry. Further refinements recent developments targeting improvements model's eddy kinetic energy (EKE), relative vorticity fields, minimized drift below thermocline which is crucial longer reanalysis scope. concurrent effort involves new encompassing Azov Sea, coupled with sea-ice model. initiative utilization different bulk formulas, enabling incorporation sea ice fluxes AGRIF capabilities. Testing enhanced configuration rigorous assessments aimed at validating efficacy these updates, ensuring comprehensive evaluation system's performance.
