R/V YUNUS-S (Istanbul University). Cruise report May 8-9, 2019 Istanbul – Istanbul

The objective of this cruise was to recover from Çınarcık Basin an instrumented frame deployed during a previous R/V Yunus-S cruise, November 12-13, 2018, recover the data recorded by the instruments, do maintenance and redeploy the frame at another site, in the Central basin. The frame was successfully recovered. The RBR/Paroscientific (Digiquartz) bottom pressure recorder functioned properly throughout the 6-month deployment. The other instrument, a Seaguard doppler recording current meter (RCM) equipped with additional sensors, operated properly for one month after deployment and stopped, presumably because of battery power failure. Pressure records from both instruments match but the noise level of the Digiquartz pressure sensor is about 1/50 of the noise level of the Aandera tide sensor fitted to the RCM. The instrumented frame was redeployed at the planned location without incident.
