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）及邻近陆架海底共计50000平方千米海域的移动无脊椎动物与鱼类生物多样性展开调查。本次调查依托QDPIF科考船“格温多琳·梅”号（Gwendoline May），在为期1个月的航次中，于148个覆盖各类已知物理环境的采样点位，采用8英寻网板拖网（otter trawl，单船高位佛罗里达飞人型拖网）完成1千米拖曳采样。共鉴定得到约1550个物种或物种等价操作分类单元（operational taxonomic units，OTU）。本数据集总计包含11325条样点-物种记录。
