Equipment performance report for the Drifting Acoustic Spar Buoy Recorder (DASBR).

Emily T. Griffiths & Jay Barlow
The Drifting Acoustic Spar Buoy Recorder (or DASBR) is an autonomous Passive Acoustic Monitoring (PAM) system developed at the Southwest Fisheries Science Center (SWFSC) to provide a practical, low-cost option for collecting high-quality marine acoustic data. Most autonomous recording systems (such as Cornell's Pop-ups and SIO's HARPS) are bottommounted and therefore limited to shelf and slope waters. Fixed moorings in deep pelagic waters are generally too expensive for common use. Hydrophone arrays towed behind research...
