Coral Sea - Kenn Seamount - Geomorphology and Surface Classification

Voyage IN2019_V04 contributed an additional 29,000 kms2 of seafloor survey data to the Coral Sea knowledge base. From this new bathymetric data individual seamounts have been extracted and have been classified to the Geoscience Australia Geomorphology Classification Scheme. This dataset contains two layers representing the classification layers- 1) Surface (Plain, Slope, Escarpment) and 2) fine scale Geomorphology of the seamount for the Kenn Seamount.Ongoing research with this survey data will provide new insights into the detailed geomorphic shape and spatial relationships between adjacent seabed features. This information will be released in future publications to show the potential of how the scale of such seafloor data can be used for predictive habitat modelling when analysed with the biological data overlays.

Voyage IN2019_V04 为珊瑚海知识库新增了29000平方千米的海底调查数据。基于这批新的水深测量数据，研究人员已提取出单个海山，并依据澳大利亚地质调查局（Geoscience Australia）地貌分类方案完成分类。本数据集包含两类分类图层：1）表层地貌（平原、斜坡、悬崖）；2）肯恩海山（Kenn Seamount）的精细尺度海山地貌。依托本次调查数据开展的后续研究，将为揭示海底相邻地貌单元的精细地貌形态与空间关联关系提供全新视角。相关研究成果将在未来发表的文献中公开，以展示此类大规模海底数据结合生物数据叠加分析时，在预测性生境建模方面的应用潜力。

背景概述

该数据集基于2019年航次获取的珊瑚海海底测绘数据，专注于肯恩海山的地貌和表面分类，包含表面类型和精细地貌两个分类层。数据集位于南纬13.12°至26.91°和东经153.07°至166.74°的珊瑚海区域，深度范围为200至5000米，旨在支持海底特征分析和预测性栖息地建模研究。
