Abundances of benthic invertebrate species in the CEAMARC region 2007/08

Percent-cover estimates from forward facing still-images collected during the benthic trawls of the 2007/08 CEAMARC voyage (raw data-set here: https://data.aad.gov.au/metadata/records/CEAMARC_CASO_200708_V3_IMAGES). All fauna in the bottom third of each image was scored to the lowest taxonomic resolution possible. The images originate from 32 transects, but were split by their lon-lat-position within a spatial grid of environmental variables into 41 sites. This dataset contains: (1)- species/ morphotypes identified to the highest taxonomic resolution possible- broader taxonomic classification (phylum/class)- each species mobility, feeding-type and body-shape if possible- average abundances in percent-cover at each site(2)- the mean longitude of all images aggregated per site- the mean latitude of all images aggregated per site- the number of images scored per site

本数据集源自2007/08年度CEAMARC航次底拖网作业期间采集的正向静止图像的盖度百分比估算值（原始数据集链接：https://data.aad.gov.au/metadata/records/CEAMARC_CASO_200708_V3_IMAGES）。每张图像底部三分之一区域内的所有底栖生物，均以尽可能最低的分类分辨率进行评分定级。该批图像源自32条调查样带，但依据其在环境变量空间网格内的经纬度位置，被划分为41个采样站点。本数据集涵盖以下内容：(1) 以最高可实现分类分辨率鉴定的物种/形态型、更宽泛的分类学归类（门/纲级别）、若可行则记录各物种的运动方式、摄食类型与体型，以及各采样站点的盖度百分比平均丰度；(2) 各采样站点聚合的所有图像的平均经度、各采样站点聚合的所有图像的平均纬度，以及每个采样站点的有效评分图像数量。
