The RUDAR™ (Remote Underwater Digital Acoustic Recorder) is a very compact, long-term autonomous recording device that is light enough to be deployed by hand from small boats. The RUDAR™ system uses a custom-made version of the new
ST400 SoundScape embedded Linux mobile data recorder. Interchangeable Cetacean Research™ C54- or C304- series hydrophones are used for signal detection. This system has very low power consumption that allows extended remote recording sessions and continuous high-speed data acquisition.
Development Background - the idea for a portable remote underwater recording device came about after several conversations in 2000 and 2001 with fisheries biologist Rodney Rountree of the University of Massachusetts at Amherst. The first conceptual RUDAR™ prototype was completed in early January 2002 for NOAA and the University of Hawaii's Coral Reef Ecosystem Investigation.
RUDAR™ Features:
- Maximum working depths of 1500m or 3500m
- Up to four hydrophone channels sampled with 24-bit resolution
- Sample rates selectable over wide frequency range
- Flexible recording scheme programmability
- Can record using two independent schemes and sample rates simultaneously
- Data written to hot-pluggable internal hard drives for very long recording times
- Ultra-fast data transfer for post processing analysis
- Embedded Linux operating system
- Light weight for easy deployment from small boats
- Rugged housing for long life in harsh oceanographic conditions
