Southern Surveyor Voyage SS 04/91 Biological Data Overview

This record is an overview entry for biological data collected on Southern Surveyor cruise SS 04/91. This cruise took place in the North West Shelf during 12-30 September 1991, under the leadership of Wade Whitelaw. Biological data collected on this cruise include demersal fish and invertebrate samples from 105 stations, with up to 70 species being caught per 30 min trawl. Greatest diversity occurred at the shallower stations. Length frequency data for 14 species of fish (see taxonomy keywords) and otoliths for 4 of the main species (L. choerorynchus, S. undosquamis, N. furcosus and L. sebae) were collected. Numerous fish specimens were retained for further taxonomic identification and stock discrimination studies. Live berried scampi samples were obtained from 3 scampi trawls for larval rearing studies (UWA). 35 mm camera photography of 63 trawls including video photography of the last trawl to study the effects of the trawl on the benthos were obtained. Numerous whale sightings were also observed during the cruise and 3 hydrographic transects were completed with the submersible data logger (SDL). Please note: This metadata record is a preliminary entry derived from information in the cruise plan and/or cruise report. Individual data types - which may span several cruises - will be indexed separately within this metadata system in due course. - Biological Field Data Sheets recorded during this voyage have been scanned to PDF, and are available (to CSIRO Staff) on-line.

本记录是南方调查者号（Southern Surveyor）SS 04/91航次所采集生物数据的概述条目。

该航次于1991年9月12日至30日在西北大陆架开展，由Wade Whitelaw带队。

本次航次采集的生物数据包括来自105个站位的底层鱼类（demersal fish）和无脊椎动物（invertebrate）样本，每30分钟拖网可捕获多达70个物种。物种多样性最高的区域位于较浅的站位。

采集了14种鱼类的体长频率数据（详见分类学关键词），以及4种主要物种（L. choerorynchus、S. undosquamis、N. furcosus和L. sebae）的耳石（otoliths）样本。保留了大量鱼类标本，用于后续分类鉴定（taxonomic identification）和种群鉴别（stock discrimination）研究。

通过3次挪威海螯虾拖网获取了抱卵活样本，用于幼体培育（larval rearing）研究（UWA）。

获取了63次拖网的35毫米相机摄影资料，包括最后一次拖网的视频记录，以研究拖网对底栖生物（benthos）的影响。航次期间还记录到多次鲸鱼目击事件，并使用水下数据记录仪（submersible data logger，SDL）完成了3条水文断面（hydrographic transects）测量。

请注意：本元数据记录是基于航次计划和/或航次报告信息生成的初步条目。各类独立数据（可能跨多个航次）将适时在本元数据系统中单独建立索引。
