Aphroditides, Polynoids) from trawl samples in the Weddell Sea and neighbouring seas during POLARSTERN cruises ANT-I/2, ANT-II/4, ANT-V/3-4, ANT-VII/4, ANT-IX/3 and ANT-X/3 between 1983 and 1992

The data set comprises a total of 3,240 records of abundance of 24 polychaete taxa of the families Aphroditides and Polynoids (88 % of the taxa were identified at species or subspecies level). The data were collected in the Southern Ocean, i.e. the Weddell Sea, the Lazarev Sea and the plateau region of South Orkney (depth range: 126 - 2025 m). A total of 135 trawls (Agassiz trawl, bottom trawl, dredge, benthopelagic trawl) were used during RV "Polarstern" cruises ANT I/2 (1983), ANT II/4 (1983/84), ANT V/3 and 4 (1986/87), ANT VII/4 (1989), ANT IX/3 (1990/91) and ANT X/3 (1992).

本数据集总计包含3240条丰度记录，涉及鳞沙蚕科（Aphroditides）与多鳞虫科（Polynoids）下的24个多毛类（polychaete）分类群，其中88%的分类群已鉴定至物种或亚种水平。该数据集的采样工作实施于南大洋海域，具体覆盖威德尔海（Weddell Sea）、拉扎列夫海（Lazarev Sea）及南奥克尼高原区域，采样水深范围为126至2025米。本次采样共计使用135组采样作业，涵盖阿加西拖网（Agassiz trawl）、底拖网（bottom trawl）、挖泥采样器（dredge）与底栖浮游拖网（benthopelagic trawl），作业开展于“极星号”（RV Polarstern）科考航次ANT I/2（1983年）、ANT II/4（1983/1984年）、ANT V/3与ANT V/4（1986/1987年）、ANT VII/4（1989年）、ANT IX/3（1990/1991年）及ANT X/3（1992年）期间。
