Maintenance and Update Frequency: notPlanned Statement: Two autonomous underwater sound recorders were deployed on the seafloor south of Bremer Bay in February 2015. One of these two recorders was a low-frequency (LF) sound recorder designed and built at the Centre for Marine Science and Technology (CMST, http://cmst.curtin.edu.au/products/underwater-sound-recorder/). It stayed in the water recording sea noise from the 10th of February 2015 to the 6th of February 2016. The recorder made 300-s recordings repeated with 900-s intervals (600-s sleep time). The housing of the recorder was equipped with cross-bars to stabilize its position on the seafloor. The second underwater sound recorder was a high-frequency (HF) SM2+ model from Wildlife Acoustics. It was recording sea noise at approximately the same location as the LF recorder from the 10th of February to the 11th of March 2015. The recorder was programmed to make recordings of approximately 960 s length repeated with 30 min intervals. A towed acoustic array was deployed from R/V Whale Song during its voyage in the Southern Ocean in January-February 2016. Recordings from the towed array were made in the region of the Bremer Canyon from about 7:00 to 22:00 WST on the 7th of February. The sampling rate of recording was 48,000 samples per second.
