The long-term goals of this project are as follows 1 to investigate the dynamics of semi-enclosed seas dominated by buoyancy input and wind forcing and influenced by complex topography and 2 to improve the understanding of coastal marine environmental evolution, with particular emphasis on eddy dynamics. The main objective of the MARMARA project is to study the near-surface dispersion and circulation in the Marmara Sea, a small 70 x 250 km basin connecting the Aegean Sea through the Dardanelles Strait to the Black Sea via the Bosphorus Strait. The investigators planned to study the surface circulation dynamics of the Marmara Sea at scales from inertialtidal to seasonal using drifter observations and ancillary satellite data sea surface temperature SST and ocean color over about a year from summer 2008 to spring 2009, in conjunction with other observational programs and numerical simulation exercises conducted by colleagues in the Turkish Straits System. The investigators deployed surface drifters in two main episodes in late summer 2008 and winter 2009 at key locations to maximize the geographical coverage of the Marmara Sea and to construct maps of mean circulation and eddy variability in terms of seasons and major wind regimes Eulerian statistics. The deployments will mostly be in small 1 nm clusters of three drifters to assess the horizontal dispersion of the surface waters Lagrangian dispersion statistics. The drifter data also will be used in concert with satellite images SST and ocean color to describe qualitatively the surface dynamics.
