IMOS - Animal Tracking Facility - Acoustic Tracking - Quality Controlled Detections (2007 -2017)

OBIS and OBIS Australia

Over the last decade, the Integrated Marine Observing System's Animal Tracking Facility (IMOS ATF) has established a permanent array of acoustic receivers around Australia to detect the movements of tagged marine animals in coastal waters. Simultaneously, IMOS ATF developed a centralised national database (https://animaltracking.aodn.org.au/) to encourage collaborative research across the user community and provide unprecedented opportunities to quantify individual behaviour across a broad range of taxa. Here we present the database and quality control procedures developed to collate 48.5 million valid detections from 1891 receiving stations. This dataset consists of detection data for 3523 tags deployed on 117 species (fish, sharks, rays, reptiles, and mammals), with distances travelled ranging from a few to thousands of kilometres. This dataset of acoustic detections 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 copy of the IMOS ATF data is of the valid detections downloaded via the metadata record at https://catalogue-imos.aodn.org.au/geonetwork/srv/eng/metadata.show?uuid=0ede6b3d-8635-472f-b91c-56a758b4e091. This dataset has been summarized by reducing the detection records to the count of detections per animal per site per day (UTC). The DwC field eventId has been used to record the transmitter serial number. The initial deployment/release of the animal has also been added to the dataset using an occurenceId of transmitter tag with a postfix of '-release'.
Details of the acoustic receiver sites is at https://catalogue-imos.aodn.org.au/geonetwork/srv/eng/metadata.show?uuid=4a97bd11-e821-4682-8b20-cb69201f3223.

N/A

This dataset was downloaded from OBIS (https://obis.org/). The records for only marine mammals, seabirds, sea turtles and rays and sharks were extracted. Records with no longitude/latitude or no date (eventDate) were excluded.
