Queensland IMOS acoustic telemetry array

This sub-facility of the Integrated Marine Observing System Animal Tracking Facility (IMOS ATF) provides infrastructure to understand the distribution and movement of key focal marine species along the coast of Queensland. Deployment of a network of acoustic receivers in conjunction with the DAF Queensland Shark Control Program and collaborator installations provides a tracking platform that spans Queensland inshore coastal and reef environments. This infrastructure enhances existing arrays managed by other research groups to provide better coverage throughout Queensland. This new infrastructure was funded by the Department of Environment and Science, Queensland, and operated by AIMS as an IMOS project (Dec 2019-June 2023), with continuation of the array beneficial to record movements of animals fitted with 10-year tags.

Acoustic receivers were deployed primarily in coastal locations with >20 collaborator groups on existing/accessible infrastructure for maintenance. Of the 327 receivers total in Queensland, AIMS and direct collaborators maintain 134 receivers (as at June 2022, current locations indicated in yellow), spanning 16.7 degress of latitude from the far northern Great Barrier Reef to Qld/NSW border. Detections are recorded from animals tagged along Australia's east coast, and 812 animals were tagged between 2019-2023, comprising 511 from priority species (conservation concern, bather concern, and fishery importance) and 301 additional species, adding value to the project.

Management of this acoustic receiver array is in conjunction with several IMOS installations (Capricorn-Bunker reefs, Stradbroke Island, in New South Wales, and nationally), and other groups (JCU, DAF, DES, UQ, Biopixel Oceans Foundation, USC, Griffith University), and data from the Queensland installation is integrated into the IMOS ATF national database, Animal Tracking (aodn.org.au). Data recorded by receivers help define the extent and timing of movement of tagged individuals of a range of management-relevant species along the east coast of Queensland. This includes enabling estimates of home ranges, dispersal distance, residency times, and migration pathways. These data can be integrated across species and with data from beyond Queensland (i.e. movements into New South Wales), to improve our understanding of space use and distribution of key species.

本设施为综合海洋观测系统动物追踪设施（Integrated Marine Observing System Animal Tracking Facility, IMOS ATF）的子设施，旨在探明昆士兰州沿岸重点海洋物种的分布特征与移动规律。本项目联合昆士兰州鲨鱼管控项目（DAF Queensland Shark Control Program）及合作方布设的声学接收基站网络，搭建了覆盖昆士兰州近岸海域与礁盘环境的全域追踪平台。该设施补强了其他研究团队已运维的接收阵列，进一步优化了昆士兰州全域的监测覆盖范围。这套新设施由昆士兰州环境与科学部资助，作为IMOS项目由澳大利亚海洋科学研究所（Australian Institute of Marine Science, AIMS）负责运营（2019年12月—2023年6月）；延续该阵列的运维，将有助于记录搭载10年寿命电子标签的海洋动物的移动轨迹。

声学接收基站主要布设于沿岸区域，现有超20个合作团队依托可访问的既有设施完成基站运维。截至2022年6月，昆士兰州全域共部署327台声学接收基站，其中澳大利亚海洋科学研究所与直接合作方负责运维134台（当前基站位置以黄色标注），监测范围覆盖16.7个纬度跨度，从最北部的大堡礁延伸至昆士兰州与新南威尔士州的州界。本项目的追踪数据采集自在澳大利亚东海岸佩戴电子标签的海洋动物，2019至2023年间共计为812头个体佩戴了标签，其中511头属于优先关注物种（涵盖受保护物种、涉泳客安全物种及渔业重要物种），另有301头来自其他物种，为项目增添了额外科研价值。

本声学接收阵列的管理工作联合了多项IMOS设施（包括新南威尔士州的卡普里科恩-邦克礁、斯特拉德布罗克岛及全国性站点）与多家合作机构：詹姆斯库克大学（James Cook University, JCU）、昆士兰州农业与渔业部（DAF）、昆士兰州环境与科学部（Department of Environment and Science, DES）、昆士兰大学（University of Queensland, UQ）、生物像素海洋基金会、阳光海岸大学（University of the Sunshine Coast, USC）、格里菲斯大学。昆士兰州站点的监测数据已整合至IMOS ATF国家级数据库——动物追踪数据库（aodn.org.au）。接收基站记录的数据可用于明确昆士兰州东海岸各类管理相关物种的标记个体的活动范围与移动时序，包括估算其活动家域、扩散距离、停留时长及洄游路径。此类数据可跨物种整合，并结合昆士兰州以外的监测数据（如进入新南威尔士州的动物移动数据），进一步深化我们对重点物种空间利用模式与分布规律的认知。
