| Definition | A submersible 16-bit digital acoustic recorder used to detect, record and monitor marine bioacoustic and ambient noise in fresh or salt water. The SM2M consists of a single hydrophone, recorder and an arrangement of 32 D cell batteries, and offers a flexible recording scheduling system. The device can also accept 1.5V alkaline batteries, 1.2V NiMH batteries or 3V (or 3.3V) lithium batteries. The instrument is designed for short-term deployments and is depth rated to 150 metres. Its sample rate ranges from 4 to 96 kHz, allowing recording frequencies up to 48 kHz. The SM2M hydrophone sensitivity is -165 dB re: 1V/uPa. Storage is available on up to four 32 Gb SDHC cards, or on up to four 128 Gb SDCX cards. Since 2015, the SM2M has been superseded by the third and fourth generation SM3M and SM4M marine recorder families, with some models able to record ultrasonic frequencies. | ||
