Modified SVP-BTC60 drifters were successfully tested in-situ near Sevastopol bay in April 2005 under support of Ukrainian NAVY Hydrograph. After this testing, two buoys (ID34859 and 34860) were deployed in the Black Sea from ship of opportunity “Sevastopol-1” along the lane “Sevastopol-Istanbul”. The buoys had a system of temperature chain packaging, updated to have the drifters automatically deployed after drop to water. According to this goal, the buoys were equipped with holder to fix the chain during transportation and avoid to get the chain entangled during self-deployment.
This deployment was next phase to investigate spring season variability of subsurface temperature in west part of the sea. New unique information was obtained that allow in combination with last year data to restore the dynamics of thermocline evolution during autumn 2004 and spring 2005.
