Brief description
Since 2007, the Integrated Marine Observing System’s Animal Tracking Facility (formerly known as the Australian Animal Tracking And Monitoring System (AATAMS)) has established a permanent array of acoustic receivers around Australia to detect the movements of tagged marine animals in coastal waters. Simultaneously, the Animal Tracking Facility developed a centralised national database (https://animaltracking.aodn.org.au/) to encourage collaborative research across the Australian research community and provide unprecedented opportunities to monitor broad-scale animal movements. The resulting dataset comprises observations of tagged animals in Australian waters collected by IMOS infrastructure as well as receivers operated by independent research projects and organisations. This dataset constitutes a valuable resource facilitating meta-analysis of animal movement, distributions, and habitat use, and is important for relating species distribution shifts with environmental covariates. This dataset comprises all available (2007 – ongoing) quality-controlled animal detections collected across the collaborative, continental IMOS network for a range of aquatic species (fish, sharks, rays, reptiles, and mammals). Here, raw animal detections collated via the IMOS Australian Animal Acoustic Telemetry Database have been quality-controlled as per Hoenner et al. (2018). This dataset is updated on a six-monthly basis. Note - There is a static snapshot of the database (up until 2017) (http://dx.doi.org/10.4225/69/5979810a7dd6f), and this has been documented in a Scientific Data Publication (Hoenner et al. 2018).Lineage
Maintenance and Update Frequency: biannually
Statement: Several factors including transmission collisions caused by multiple transmitters within range of the same receiver, environmental noise or historical duplicate transmitter IDs, can generate erroneous data from acoustic telemetry systems. Over the years, statistical methods have been developed to automatically flag possible invalid detections. In Hoenner et al. (2018), IMOS developed a flexible quality control (QC) procedure for acoustic detection data that assesses, for each individual tag (note: only VEMCO/INNOVASEA tags were used in this study), the validity of acoustic detections based on a computed set of metrics. This QC procedure is available via the {remora} R package (https://imos-animaltracking.github.io/remora/) and can be used freely by acoustic telemetry researchers or other telemetry networks. We applied this QC algorithm to the raw detections stored in the IMOS Animal Acoustic Telemetry Database. The QC outputs an extra field, ‘Detection_QC’, summarising the output of the five tests undertaken on individual detections, i.e. ‘FDA_QC’, ‘Distance_QC’, ‘Velocity_QC’, ‘DetectionDistribution_QC’, and ‘DistanceRelease_QC’. If the five tests yielded a valid QC flag of 1, then ‘Detection_QC’ is assigned 1, meaning the detection is deemed ‘valid’. If only four of these fields had a QC flag of 1 then ‘Detection_QC’ = 2, meaning the detection is ‘likely to be valid’. Detections having three or less than three of these five fields with a QC flag of 1 are considered ‘likely invalid’ or ‘invalid’, respectively.
