Passive acoustic monitoring data recorded by recorder AU0302 at mooring F4-OZA2 in Fram Strait in 2020/2021 ...

Passive acoustic monitoring (PAM) data were collected by recorder AU0302 of type AURAL (Autonomous Underwater Recorder for Acoustic Listening (AURAL; Model 3, Multi-Électronique) at 79.1669° N, 6.3327° E, mooring F4-OZA2, in Fram Strait. During a deployment period from July 2020 to July 2022, passive acoustic data were collected from July 2020 to May 2021 (recording period) by AU0302 as part of the Frontiers in Arctic Marine Monitoring (FRAM) observatory in Fram Strait. The recorder was moored at 300 m depth and scheduled to record at a duty cycle of 10 min per 1 h at a sample rate of 32,000 Hz. Due to a firmware bug, the set duty cycle changed on 2021-01-02 to continuous recording of files with 10 min duration. Further details about the data acquisition and processing of this data set can be found in the accompanying metadata file (see Additional metadata) as well as the data processing report (see Data Processing Report). Passive acoustic data archived here represent data processing Level 1+, according to ... : Each daily .tar contains the 10-minute audio files (.wav format) collected during the respective day.--Please note that this data set may also be listed as ARKF04-OZA2_AU0302_1 at other data portals, such as the Open Portal to Underwater Soundscapes (OPUS), available at https://opus.aq. ...
