Wollongong seabed landforms derived from multibeam echosounder data 2022

Multibeam echosounder (MBES) bathymetry data were collected offshore of Wollongong, NSW in 2016-17. Bathymetry data coverage extends from Bellambi Point to Port Kembla, and ranges from 4 to 62 m depth. This dataset represents a classification of seabed landforms derived from this MBES, which delineates the prominent seabed features observed. This classification defines areas of reefs, peaks, plains, scarps, depressions and channels. Features were classified using the Seabed Landforms Classification Toolset developed for ArcGIS by the Coastal and Marine Unit, DPE (Linklater et al. 2023) which are publicly available on SEED (https://datasets.seed.nsw.gov.au/dataset/seabed-landforms-classification-toolset) and GitHub (https://github.com/LinklaterM/Seabed-Landforms-Classification-Toolset/). \r\n\r\nA preliminary classification of this Wollongong survey was presented in Linklater et al. (2019), and this classification represents the final interpreted product for this survey. This dataset contributes toward an understanding of the distribution of submerged reefs along the NSW coast, which provides fundamental baseline information for managers, users and custodians of the marine environment. \r\n\r\nThe source MBES dataset for this classification is available on the Australian Ocean Data Network portal: https://portal.aodn.org.au/\r\n\r\nLinklater, M., Morris, B.D. and Hanslow, D.J.

2016至2017年，于澳大利亚新南威尔士州（New South Wales, NSW）伍伦贡（Wollongong）近岸海域采集了多波束测深仪（Multibeam Echosounder, MBES）水深地形数据。本次采集的水深地形数据覆盖范围从贝拉米角（Bellambi Point）至肯布拉港（Port Kembla），水深范围为4至62米。本数据集为基于上述MBES数据提取并分类的海底地貌类型，精准勾勒出研究区内清晰可见的典型海底地貌特征。该分类体系涵盖了礁体、海峰、海床平原、陡坡、凹陷与水道等地貌类型。地貌分类工作采用了新南威尔士州规划与环境部（Department of Planning and Environment, DPE）海岸与海洋单元针对ArcGIS软件开发的《海底地貌分类工具集》（Seabed Landforms Classification Toolset），该工具集已在SEED平台（https://datasets.seed.nsw.gov.au/dataset/seabed-landforms-classification-toolset）与GitHub开源仓库（https://github.com/LinklaterM/Seabed-Landforms-Classification-Toolset/）公开发布，相关成果见于Linklater等人2023年的研究。

伍伦贡海域本次调查的初步地貌分类结果曾于Linklater等人2019年的研究中发表，本数据集为该调查的最终解译成果。本数据集有助于明晰新南威尔士州沿岸水下礁体的分布格局，可为海洋环境的管理者、使用者与管护者提供基础的基准数据。
