Forster (Cape Hawke to Black Head), NSW Bathymetry Acquisition (20190018S)

The Forster, Cape Hawke to Black Head, bathymetry survey was acquired by the NSW government (Department of Planning and Environment – DPE) onboard the RV Bombora during the period 27 Feb 2019 – 14 Oct 2020, using DPE’s R2Sonic 2022 multibeam sonar. The survey was completed as part of the SeabedNSW program funded by NSW government through Coastal Reforms (>2015), HabMap Program funded through Marine Parks Authority (now under Marine Estate Management Authority) or through collaborations with partner agencies or institutions. The purpose of the project was to 1) provide a baseline dataset and 2) map the spatial distribution of seabed types. This dataset contains 32-bit floating point geotiff files of bathymetry and backscatter in 5m resolution for the study area, derived from the processed Hypack, R2Sonic GUI, POSView, POSPac, Qimera and FMGT software. General details on vessel setup, mobilisation and processing are provided at https://www.environment.nsw.gov.au/-/media/OEH/Corporate-Site/Documents/Research/Our-science-and-research/seabed-nsw-standard-operating-procedures-multibeam-surveying-190101.pdf with survey specific details in the Survey Report and DPIE Rigor Statement (can be provided upon request).This dataset is not to be used for navigational purposes.

本次霍克斯角（Cape Hawke）至黑角（Black Head）海域的福斯特片区水深测绘调查，由新南威尔士州政府规划与环境部（Department of Planning and Environment，缩写DPE）于2019年2月27日至2020年10月14日期间，在“邦博拉号”（RV Bombora）研究船上完成，测绘所用设备为DPE配备的R2Sonic 2022多波束声呐（multibeam sonar）。本次调查作为SeabedNSW项目的一部分开展，该项目由新南威尔士州政府通过2015年起实施的海岸改革计划（Coastal Reforms）提供资助；同时也属于HabMap项目的工作范畴，该项目原由海洋公园管理局（现隶属于海洋资产管理局）资助，或由合作机构与伙伴单位共同支持。本项目的目标为：1）构建基准数据集；2）绘制海底类型的空间分布图谱。本数据集包含研究区域内分辨率为5米的水深测绘与海底反向散射强度数据的32位浮点型GeoTIFF（geotiff）文件，数据源自经Hypack、R2Sonic GUI、POSView、POSPac、Qimera及FMGT软件处理后的成果。关于船舶配置、动员部署及数据处理的通用细节，可参阅链接https://www.environment.nsw.gov.au/-/media/OEH/Corporate-Site/Documents/Research/Our-science-and-research/seabed-nsw-standard-operating-procedures-multibeam-surveying-190101.pdf；本次调查的专属细节则收录于《调查报告》与DPIE严谨性声明（可按需索取）。本数据集不得用于导航用途。
