Results of nodule detection along AUV track SO242/1_41-1_AUV5 (Abyss_191) during SONNE cruise SO242/1

Images were acquired by the DeepSurvey Camera on board GEOMAR's AUV Abyss. Nodules were delineated by the CoMoNoD algorithm [see related to references]. Result files are computed per AUV dive. Nodule detections below 5cm^2 are neglected as are detections above 707cm^2. Abundance statistics are computed per m^2 and gridded per m^2 as well. For overlapping images, max-pooling has been applied to select the values reported in the result files. Pixel values in the rendered maps correspond to the units reported in the ASCI files (median-nodule-size: cm^2, nodule-number: m^-2, percent-coverage: %, sorting, skewness and pixel-contributions are unit-free).

本数据集的图像由GEOMAR旗下的“阿比斯号”自主水下航行器（Autonomous Underwater Vehicle，AUV）搭载的DeepSurvey相机（DeepSurvey Camera）采集获取。结核轮廓由CoMoNoD算法（CoMoNoD algorithm）勾勒划定[详见相关参考文献]。结果文件按单次AUV下潜任务生成。面积小于5平方厘米（cm²）或大于707平方厘米（cm²）的结核检测结果将被剔除。丰度统计以每平方米（m²）为单位进行计算，并同样以每平方米（m²）为单位完成网格化处理。针对存在重叠的图像，采用最大池化（max-pooling）操作选取结果文件中记录的数值。渲染生成的地图中，像素值与ASCI文件中记录的单位保持一致：结核中位尺寸单位为平方厘米（cm²），结核数量单位为每平方米（m⁻²），覆盖率单位为百分比（%），排序、偏度及像素贡献度均为无量纲量。
