The objective of this cruise was to the final recovery, from Imrali Basin of an instrumented frame deployed during a previous Istanbul University R/V Yunus-S cruise, Nov 19-20, 2019. Because of COVID-19 restrictions, the recovery cruise, initially planned in May 2020 was delayed until November The frame was successfully recovered, but instruments were out of battery power. The RBR/Paroscientific (Digiquartz) bottom pressure recorder functioned continuously for 4 months and 10 days, then suffered cyclic perturbations and interruptions due to battery problems until June 24, 2020 when it stopped. The other instrument, a Seaguard doppler recording current meter (RCM) equipped with additional sensors (conductivity, pressure, temperature) provided 4.5 month of hourly data, but with cyclically missing records (1/3) after 1.5 months.
