IMOS - Animal Tracking Facility - Acoustic Tracking - Quality Controlled Detections (2007 -2021)

Over the last decade, the Integrated Marine Observing Systems 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 67 million valid detections from 1891 receiving stations. This dataset consists of detection data for 7800 tags deployed on 154 species (fish, sharks, rays, reptiles, and mammals), with distances traveled 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 IMOS Animal Tracking Portal at https://animaltracking.aodn.org.au/detection. 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 organismId has been used to record the transmitter serial number. The initial deployment/release of the animal has also been added to the dataset via EMoF using an occurrenceId of the transmitter tag with a postfix of '-release'. Parameters include transmitter type, length and weight of the released animal.

近十年来，海洋综合观测系统动物追踪设施（Integrated Marine Observing Systems Animal Tracking Facility，IMOS ATF）已在澳大利亚周边布设永久性声学接收器阵列，用于监测加装电子标记的海洋动物在近岸水域的移动轨迹。与此同时，IMOS ATF搭建了国家级集中式数据库（https://animaltracking.aodn.org.au/），旨在推动用户群体间的协作研究，并为量化众多生物类群的个体行为提供了前所未有的契机。本研究公开了该数据库及配套的质量控制流程，该流程用于整合来自1891个接收站点的6700万条有效探测记录。本数据集包含针对154个物种（鱼类、鲨类、鳐类、爬行类及哺乳类）所部署的7800个标记的探测数据，标记动物的移动距离从数公里至数千公里不等。这套声学探测数据集为动物移动、分布及栖息地利用的荟萃分析提供了宝贵资源，同时也为探究物种分布变化与环境协变量之间的关联提供了重要支撑。
本次提供的IMOS ATF数据集副本为通过IMOS动物追踪门户（https://animaltracking.aodn.org.au/detection）下载的有效探测数据。本数据集已进行汇总处理：将原始探测记录精简为每只动物、每个站点、每日（协调世界时UTC）的探测次数统计。已采用达尔文核心（Darwin Core，DwC）字段中的organismId来记录发射器序列号。已通过测量与事实扩展（Extension of Measurement or Facts，EMoF）字段，将动物的初始投放/释放信息添加至数据集中，其关联的occurrenceId为发射器标记的ID后接后缀'-release'。数据集包含的参数包括发射器类型、释放动物的体长与体重。
