µRUDAR™
The Cetacean Research™ µRUDAR™ (micro Remote Underwater Digital Acoustic Recorder) is a very compact, short-term, autonomous recording device that is designed for fast and easy deployment in a wide range of applications. Uses range from remote detection of methane bubbles to recording wild cetacean vocalizations during the night. The µRUDAR™ uses the Sensor Technology SQ26-06 hydrophone and the M-Audio MicroTrack II digital recorder with a 16GB industrial-grade compact flash memory card. This easy-to-use recording system can be deployed to depths of up to 250m and will provide more than 10 hours of continuous 24-bit, 96kHz sample-rate data acquisition.

RUDAR™
The Cetacean Research™ RUDAR™ (Remote Underwater Digital Acoustic Recorder) is a compact, long-term autonomous recording device that is light enough to be deployed by hand from small boats. The RUDAR™ system utilizes the data acquisition and processing components of the new ST1400ENV mobile data recorder & sound level monitor. Interchangeable Cetacean Research™ C55- 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:
- Working depths of more than 1000m available
- 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
- Light weight for easy deployment from small boats
- Rugged housing for long life in harsh oceanographic conditions
