KuramBio 2012_Lebensspuren and benthic fauna area data

Lebensspuren data genrated by the random selection of 50 frames per station of the KuramBio 2012 expedition (8 stations analyzed; the depth of the stations ranged from 4,868 m to 5,768 m). In these 400 frames, the area of 5,692 lebensspuren was measured and the lebensspuren were classified. Additionally, megabenthic fauna was quantified and classified as "faunal coverage" at each station, which was the area covered by all individual megabenthic organisms. This "faunal coverage" area is based on the measurements of 4,009 individual animals. Environmental variables: content of grain fractions (%Sand, %Silt/Clay), organic carbon in the sediment (total weight (wt%) of the sediment), and chlorophyll-α concentrations (Chl.-α, μg/g) were obtained from previously published data on the studied stations (Sattarova and Artemova, 2015; Schmidt et al., 2019).本数据集的生物遗迹（Lebensspuren）数据源自KuramBio 2012年科考航次的8个分析站位，每个站位随机选取50帧图像，共计得到400帧分析图像；各站位水深范围为4868米至5768米。在这400帧图像中，研究人员对5692个生物遗迹的面积进行了测量并完成分类。此外，各站位还对大型底栖动物（megabenthic fauna）开展量化工作，并以“动物覆盖度”为指标进行分类，该指标指所有单个大型底栖生物所占的总面积。该“动物覆盖度”的面积数据基于4009个个体动物的测量结果。环境变量包括沉积物粒度组分占比（%砂粒、%粉砂/黏土）、沉积物有机碳含量（以沉积物总重量百分比wt%计）以及叶绿素-α浓度（Chl.-α，μg/g），上述数据均取自已发表的对应站位研究文献（Sattarova与Artemova，2015；Schmidt等，2019）。
