2009 University of Plymouth Wave Hub, Cornwall towed underwater video baseline benthic survey

This data set comprises of marine epibenthos (74 identified taxa derived from Algae, Annelida, Arthropoda, Bryozoa, Chordata, Cnidaria, Echinodermata, Mollusca, Nemertea, Porifera) quantified in June 2009 at The Wave Hub development zone, a Marine Renewable Energy Installation (MREI) in Hayle, Cornwall, South West UK. At each site a 200 x 0.5 metre transect of the seabed was undertaken. The survey was carried out as a baseline to characterise the seabed fauna present, prior to any subsea infrastructure being deployed at the test site. The design was also replicated to the east and west of the Wave Hub site to provide controls for future impact assessment.本数据集包含海洋底上生物（marine epibenthos），共计74个已鉴定分类群，这些类群分别隶属于藻类（Algae）、环节动物门（Annelida）、节肢动物门（Arthropoda）、苔藓动物门（Bryozoa）、脊索动物门（Chordata）、刺胞动物门（Cnidaria）、棘皮动物门（Echinodermata）、软体动物门（Mollusca）、纽形动物门（Nemertea）以及多孔动物门（Porifera）。该数据集的生物量化统计工作于2009年6月在英国西南部康沃尔郡海勒镇的海浪枢纽（Wave Hub）开发区完成，该区域为一处海洋可再生能源装置场址（Marine Renewable Energy Installation, MREI）。所有调查站点均布设了200米×0.5米的海底样带开展采样调查。本次调查属于基线调查，旨在表征该测试场址在部署任何海底基础设施前的现有海底动物群落特征。此外，该调查设计在海浪枢纽场址的东侧与西侧进行了重复布设，以设置对照样区，用于后续的海洋工程影响评估。
