| Acoustics Frequencies (kHz): | 38, 70, 120, 200 |
| Acoustics Mode: | CW |
| Acoustics Calibration: | 38.1 mm WC @ 4.25 m |
| Optics Calibration: | 10 cm long 3 tags at 1, 2, and 3 m |
| Logging range (m): | 100 |
| Deployment Depth (m): | 130 |
| Planning Comments: | CW deployment to check buoyancy. |
| Operation Comments: | Adjusted the float to reduce sinking rate. Achieved a sinking rate of 0.4 m/sec comparable to previous PLOAS rate ~ 0.33 m/sec. 70 kHz is still troubling and not pinging always. Need checking before next deployment. Starboard strobe failed – looks like a connection issue. Unable to evaluate camera quality. May need to adjust settings? Video seems to be dark – need to open aperture little more. Need to set camera time to UTC (except starboard camera). Picture captured time is in local time and possibly Sony camera may be using time from its internal clock time – Rob will investigate this. Need to set camera picture numbers synchronised. Decided to clear memory card so that all photo numbers are synchronised between cameras. Camera aspect ratio changes when PLOAS is swinging – or orientation of camera changing. Some settings may need to change in camera so that aspect ratio is locked always – communicated to Rob. Oblique camera was not giving same number of images as compared to vertical – possibly oblique camera may not be capturing image at every 1 second. Impulse noise in data – significant in 38 kHz – maybe USBL? Will check. |
