Marine Futures Project - Abrolhos Islands - biota

The Marine Futures Project was designed to benchmark the current status of key Western Australian marine ecosystems, based on an improved understanding of the relationship between marine habitats, biodiversity and our use of these values. Approximately 1,500 km2 of seafloor were mapped using hydroacoustics (Reson 8101 Multibeam), and expected benthic habitats "ground-truthed" using towed video transects and baited remote underwater video systems. Both sources of information were then combined in a spatial predictive modelling framework to produce fine-scale habitat maps showing the extent of substrate types, biotic formations, etc.

Surveys took place across 9 study areas, including the Abrolhos Islands, a group of 122 limestone outcrops surrounded by fringing reed ca. 60km west from the city of Geraldton. The Abrolhos research location is the most northerly of the Marine Futures sampling sites, selected due to the unique mixture of tropical coral reef habitats, and temperate reef and seagrass communities.The hydroacoustics data were processed to construct full coverage maps of bathymetry and textural information.

海洋未来项目（Marine Futures Project）旨在基于对海洋栖息地、生物多样性与人类对这些生态资源利用之间关系的更深入认知，对西澳大利亚州关键海洋生态系统的现状开展基准评估。研究团队采用水声测绘（hydroacoustics）技术搭配Reson 8101多波束测深系统（Reson 8101 Multibeam），完成了约1500平方千米海底区域的测绘工作；同时通过拖曳视频样带与诱饵式远程水下视频系统，对预设底栖生境（benthic habitats）开展实地地面校验（ground-truthed）。随后将两类数据源整合至空间预测建模框架中，生成了涵盖基底类型、生物群落等要素的精细尺度生境分布图。

本次调查覆盖9个研究区域，其中包括阿布洛霍斯群岛（Abrolhos Islands）——这是一处由122座石灰岩露头组成的群落，坐落于杰拉尔顿市以西约60千米处，被沿岸芦苇带环绕。阿布洛霍斯群岛是海洋未来项目最北端的采样点位，其入选缘由为该区域兼具热带珊瑚礁生境、温带礁体与海草群落的独特复合生态系统特征。

水声测绘数据经处理后，生成了覆盖全区域的水深地形与纹理信息分布图。
