CCS - CCS_SF_03 Mooring data May 2019 deployment EDGE System

This bio-acoustic data was collected between the 7th May 2019 and the 18th November 2019 at the proposed site for subsea CCS off Gippsland, Victoria using the EDGE system. \n\nData summary:\nTurret system experienced problems where rotation of the system failed sometime after deployment. E&T sent a team to fix this. \n\nEDGE System:\nThe EDGE system comprises a Simrad WBAT self contained echosounder connected to a Simrad ES70-7CD 70 kHz 7 degree transducer. The transducer is set atop a turret where a belt driven motor rotates the transducer through 360 degrees over a 20 minute period. A second rotation of 20 minuts occurs to take the transducer back to the starting postion. The rotation comprises steps of 7 degrees rotation where 20 pings are recorded at each step. \n\nThe EDGE system was mounted to seafloor lander 2 (CCS_SF_03) and was deployed on the 7th of May 2019 in approximately 120m of water at site proposed for subsea CCS (38.2566S, 147.4247E). \n\nParameter | Value\nTransducer manufacturer | Simrad\nTransducer model | ES70-CD\nTransducer serial number | 120\nTransceiver manufacturer | Simrad\nTransceiver model | WBAT\nTransceiver serial number | 253667\n\nFrequency (kHz) | Power (W) | Pulse duration (ms) | Ping Rate (pings per second) | Ping Rate (pings per second)\n70 | 500 | 2.048 | 450 | 1.2\n\nEchosounder system was uncalibrated.
