Aegean Circulation Based on the 2002 Pilot Drifter Array
A collaboration between the University of Miami, the Greek National Center of Marine Research and the University of
Athens.

GPS Units
• Holey sock drogue at 10 m mid-depth.
• GPS navigation and one hour reporting.
• Uplink through ARGOS.
• Data on GTS and website link.
• Hull Sea Surface Temperature
• Stranding recovery by NCMR and U. Athens.

Program involved deployment of 30 Global Positioning System/ARGOS drifters.
Drogues are WOCE standard by at a 10m mid-depth rather than the 15 m. This is to allow shallow water capability.
Launches were done from IMS cruises.

Some M2 tide
Tradition is that this component is weak: Island scattering on coast?

Conclusions
• A thirty drifter array in 2002 provides a rich starting point to begin a new assessment of not only the Aegean, but marginal seas with complicated topographies in general.
• The data is still being collected; but the results to date suggest a very rich set of results.
