| 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... |

| 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... |

| 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... |

| The objectives were (1) to recover acoustic ranging data logged by the Geomar and LGO acoustic transponder networks since the previous data recovery cruise (on R/V Yunus, May 4 and 5, 2017) (2) to recover as many of the 4 LGO "Fetch" acoustic transceivers as possible (4) to deploy at the seafloor the BPR mooring frame prepared by DT-INSU for bottom pressure and current recording. All the equipment shipped by GEOMAR (from Kiel), LGO and DT-INSU (both from Brest) were on board as well as 4 wooden boxes prepared for the return shipment of the LGO geodetic beacons. The Geomar beacons remained silent, but data could be downloaded from 3 or the 4 LGO beacon, thus providing measurements of all baselines of the French network; 2 of the 4 LGO acoustic beacons... |

| The objective of this cruise was to recover from the Central Basin an instrumented frame deployed during a previous Istanbul University R/V Yunus-S cruise, May 8-9, 2019, recover the data recorded by the instruments, do maintenance, and redeploy the frame at another site, in Imrali 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 during the whole period, except for the conductivity sensor. The instrument was at the outlet of a canyon located close to the epicenter of the Sept 26, 2019 Magnitude 5.8 earthquake. Following the... |
