In 2021 an AAD Moored Acoustic Recorder was integrated into each of the three KOMBIs deployed during the TEMPO voyage. MARs contained a factory calibrated HTI hydrophone and AAD-calibrated electronics that recorded continuously producing hour-long wav files at 12 kHz sample rate 16-bit depth. The start date and time of each recording is embedded in the file name of each wav file (i.e. yyyy-mm-dd_HH-MM-SS). Passive acoustic recorders recorded low and mid-frequency sounds that may be used for investigation of physical environment (e.g. ice, wind, waves, earth), biological environment (e.g. animal vocalisations and sounds) and anthropogenic noise (e.g. sounds produced by ships, construction, and other human activities). These data are for recorder 001 - also see the metadata records for recorders 002 and 003. {"type": "Point", "coordinates": [62.0613, -66.5661]} 62.0613 62.0613 -66.5661 -66.5661 AMD AMD/AU CEOS EARTH SCIENCE > OCEANS > OCEAN ACOUSTICS > AMBIENT NOISE EARTH SCIENCE > OCEANS > OCEAN ACOUSTICS > AMBIENT NOISE > BIOLOGICAL AMBIENT NOISE EARTH SCIENCE > OCEANS > OCEAN ACOUSTICS > AMBIENT NOISE > PHYSICAL AMBIENT NOISE EARTH SCIENCE > OCEANS > OCEAN ACOUSTICS > AMBIENT NOISE > TOTAL AMBIENT NOISE GEOGRAPHIC REGION > POLAR HYDROPHONES KOMBI MOORINGS OCEAN > SOUTHERN OCEAN Passive Acoustic Recorder GET DATA > DIRECT DOWNLOAD documentDigital Download the dataset.
