Abundance of epibenthic fauna on a Deep-Sea Cliff offshore Greenland and the Associated Epibenthic Fauna

Abundance data of the epibenthic fauna annotated on each photograph taken with the ROV Isis (NOC, UK) at a deep-sea wall located offshore the West coast of Greenland (Labrador Sea, [63°51.9'N, 53°16.9'W, depth: 703 to 803 m]). Abundances were standardized to 1 m² using the images' total area. Screenshots of the morphospecies are presented in the morphospecies guide pdf. These data were used to assess for differences in community composition analysis pooled in 20 m² samples defined according to high-resolution terrain abiotic clusters computed in an unsupervised way.

本数据集包含格陵兰岛西海岸外海域（拉布拉多海，坐标[63°51.9'N, 53°16.9'W]，水深703至803米）的深海海壁影像的丰度数据，该系列影像由英国国家海洋学中心（NOC）的伊西斯号遥控水下机器人（ROV，Remotely Operated Vehicle）拍摄，并针对每张照片中的底表动物群落（epibenthic fauna）完成标注。基于各影像的总覆盖面积，将丰度标准化为每平方米（1 m²）的丰度值。形态种（morphospecies）的截图已收录于《形态种指南》PDF文档内。本数据集已被用于评估经20平方米合并采样单元整合后的群落组成差异，这些采样单元由以无监督方式计算得到的高分辨率地形非生物聚类所定义。
