The primary objectives of this cruise were to recover an instrumented frame deployed in Kumburgaz basin during a previous R/V Yunus-S cruise January 29-30, 2018, recover the data recorded by the instruments, do maintenance and redeploy the frame at another site, in Çınarcık Basin. This cruise was also an opportunity to perform coring in Kumburgaz basin with a light gravity corer provided by İTÜ. The frame was successfully recovered. The bottom pressure recorder functioned until battery failure August 14, 2018. The other instrument (a Seaguard doppler recording current meter equipped with additional sensors) had failed during descent because of an insulation fault on a sensor and did not provide any useful data. The instrumented frame was redeployed at the planned location without incident.
