Terrain model of the Håkon Mosby Mud Volcano (10 m grid size)

The Håkon Mosby Mud Volcano is a natural laboratory to study geological, geochemical, and ecological processes related to deep-water mud volcanism. High resolution bathymetry of the Håkon Mosby Mud Volcano was recorded during RV Polarstern expedition ARK-XIX/3 utilizing the multibeam system Hydrosweep DS-2. Dense spacing of the survey lines and slow ship speed (5 knots) provided necessary point density to generate a regular 10 m grid. Generalization was applied to preserve and represent morphological structures appropriately. Contour lines were derived showing detailed topography at the centre of the Håkon Mosby Mud Volcano and generalized contours in the vicinity. We provide a brief introduction to the Håkon Mosby Mud Volcano area and describe in detail data recording and processing methods, as well as the morphology of the area. Accuracy assessment was made to evaluate the reliability of a 10 m resolution terrain model. […]

哈科恩·莫斯比泥火山，作为研究深海泥火山相关的地质、地球化学和生态过程之自然实验室，具有显著的科学价值。在“极地星”号科考船ARK-XIX/3航次中，利用Hydrosweep DS-2多波束系统对哈科恩·莫斯比泥火山的精细水深地形进行了记录。调查线的密集分布和缓慢的船速（5节）确保了必要的点密度，从而生成了规则的10米网格。为保留并适当地表征地貌结构，进行了概括处理。等深线绘制展示了哈科恩·莫斯比泥火山中心区域详细的拓扑地貌以及周边地区的概括等深线。本报告对哈科恩·莫斯比泥火山区域进行了简要介绍，并详细描述了数据记录与处理方法，以及该区域的地貌特征。此外，还进行了精度评估，以评价10米分辨率地形模型的可靠性。
