Mapping and Characterisation of Key Biotic and Physical Attributes of the Torres Strait Ecosystem (Prawn Trawl)

The mobile invertebrate and fish biodiversity of the 50,000 km² area of the Torres Strait Protected Zone and adjacent shelf seabed was sampled by a 1 km tow of a 8 fthm otter trawl (single high-flying Florida Flyer) at 148 sites, representing a wide range of known physical environments, during one 1-month-long voyage on the QDPIF vessel Gwendoline May. About 1,550 species/species-equivalent OTUs (operational taxonomic units) were identified. The dataset comprises 11,325 site-by-species records.

本数据集针对托雷斯海峡保护区（Torres Strait Protected Zone）及相邻陆架海床总计50000平方公里海域内的移动无脊椎动物与鱼类生物多样性开展采样调查。本次调查依托昆士兰州农渔厅（QDPIF）所属科考船"格温多琳·梅号"（Gwendoline May）完成，航次为期1个月。调查在148个覆盖多样已知物理环境的采样位点开展，采用8英寻桁拖网（单台高空作业型佛罗里达飞翼拖网）进行1公里拖曳采样。本次采样共鉴定出约1550个物种或物种等价操作分类单元（operational taxonomic units，简称OTU）。本数据集共计包含11325条位点-物种关联记录。
