MicroMARS opens the door to routine and cost effective underwater acoustic monitoring on a large scale. To date, acoustic recorders have tended to be ponderous devices in large housings crammed full of batteries and storage devices. With microMARS, these days are gone. Making use of the latest miniaturized storage, data transfer and processing technology, microMARS is the size of a ‘tall boy’, yet it packs a punch: up to two terabytes of memory translates to 460 days of storage continuous at 25kHz sample rate, or 46 days at the recorders maximum 250kHz rate. A single ‘D’ size lithium battery is sufficient to operate the recorder for approximately 10-12 days at 25-250kHz. An acoustic event detector marks data segments of potential interest. With its replaceable transducer end caps, microMars can be optimized for high or low frequency sampling, and housing options are available for 300m, 1000m and 4000m depth ratings.






Cost Effective Solution

 Combine microMARS with our ARC-1 Acoustic Release, and you have a complete, miniature sized acoustic monitoring package for significantly less than an acoustic recorder alone otherwise costs. Attach a SeaTag or PERC device and you have a way to physically locate a device that has gone “missing” (for example: the equipment could have been caught up in someone’s fishing gear, moved several kilometers away, and eventually lost.) The microMARS Software (MM-SW) is included with purchase.

 microMARS development was sponsored by National Oceanic and Atmospheric Administration’s (NOAA) Advanced Sensor Technology Working Group (ASTWG) in order to facilitate deployment of large and dense monitoring arrays that were previously cost prohibitive. We are also partnering with our friends at Bio-Waves who will provide data analysis services related to deployment/retrieval and analysis of data collected from microMARS. The project is now nearing completion. Bio-Waves specializes in marine animal bioacoustics and has extensive experience with post-processing and analysis of data collected from autonomous recorders, including automated detection and classification of marine mammal calls, underwater noise measurement, detection and measurement of sonar signals, and other types of analyses.
