Seabed Habitats and Hazards of the Joseph Bonaparte Gulf and Timor Sea, Northern Australia

The Joseph Bonaparte Gulf and Timor Sea region (JBG-TS) is an area of significance for multiple resource needs, from marine planning to offshore industry development. As such, information on seabed environments in this region is of interest to both industry and marine management. Geoscience Australia is focussed on the collation and preparation of regional pre-competitive environmental datasets, the outputs of which can be used for pre and post-bid environmental assessments and for emergency response planning.

This report provides a spatial synthesis of seabed environments for the Joseph Bonaparte Gulf and Timor Sea region (JBG-TS) by identifying and describing significant habitats, communities, and potential geohazards. Data are sourced from existing literature, including publicly available industry data, as well as data collected from two seabed mapping surveys to the Van Diemen Rise in the eastern Timor Sea (GA-322 and GA-325).

约瑟夫·波拿巴湾与帝汶海区域（Joseph Bonaparte Gulf and Timor Sea，简称JBG-TS）在海洋规划、近海产业开发等多类资源需求领域均具有重要价值。因此，该区域的海底环境信息受到产业界与海洋管理部门的共同关注。澳大利亚地球科学局（Geoscience Australia）目前致力于区域性预竞争性环境数据集的整理与编制工作，其产出成果可用于竞标前后的环境评估以及应急响应规划。
本报告针对约瑟夫·波拿巴湾与帝汶海区域（JBG-TS）的海底环境开展空间综合分析，对区域内的重要生境、生物群落以及潜在地质灾害进行识别与描述。本次研究的数据来源包括现有文献资料、公开可获取的产业数据，以及针对帝汶海东部范迪门海隆开展的两次海底测绘航次（GA-322与GA-325）所采集的数据。
