Eddies in the western Adriatic current downstream of cape Gargano: predictions, monitoring, and adaptive sampling during the DART experiment

As part of the Dynamics of the Adriatic in Real-Time (DART) international collaborative project, a real-time coastal monitoring and prediction system was implemented with a focus on the study of the complex dynamics of the swiftly-evolving fronts and eddies of the Western Adriatic Current (WAC) in the central Adriatic Sea. During August and September 2006, a series of anticyclones formed in the WAC downstream of Cape Gargano. They were directly observed in real-time through remotely sensed Chlorophyll and Sea Surface Temperature imagery from MODIS Aqua, and by ship and mooring measurements. Three trawl-resistant, profiling SEPTR moorings deployed across the WAC show mesoscale variability in the mixed layer slope across the current and anti-cyclonic horizontal shear in currents except during a period of high winds. The anti-cyclonic eddies were successfully forecast by both the Navy Coastal Ocean Model (NCOM) and Adriatic Regional Ocean Modeling System (AdriaROMS) nowcast/forecast systems. The forecasts from these models, validated using remote sensing, were used to redirect ship sampling to provide high-resolution measurements of these eddy features.
