Courageous Cruise 047 Biological Data overview, 1979

This record describes the datasets obtained on Courageous Cruise 047. The data were obtained from the Great Australian Bight in March and April 1979. Data were obtained from acoustic and trawl surveys of pelagic and demersal fish. New species distributions were obtained for fish including the footballer sweep (Neatypus obliquus), stargazer (Pleuroscopus psuedodorsalis), and various myctophids. Four species from trolling included Bonito (Sarda orientalis), Southern bluefin tuna (Thunnus maccoyi), Albacore (Thunnus alalunga) and Skipjack tuna (Katsuwonus pelamis). Length, numbers, weight and target signal strength were determined. Selected species of sponges were kept for taxonomic studies. Plankton observations were made in connection with studies of the distribution of pilchard (Sardinops neopilchardus). Additional information regarding this dataset is contained in the cruise summary for this voyage.(derived from the cruise report) - Biological Field Data Sheets recorded during this voyage have been scanned to PDF, and are available (to CSIRO Staff) on-line.

本记录描述了“Courageous Cruise 047”航次获取的数据集。这些数据于1979年3月至4月在大澳大利亚湾（Great Australian Bight）采集，来源于中上层鱼类（pelagic fish）和底层鱼类（demersal fish）的声学调查与拖网调查。研究获得了斜带新鳍鱼（footballer sweep，Neatypus obliquus）、瞻星鱼（stargazer，Pleuroscopus psuedodorsalis）及多种灯笼鱼（myctophids）等鱼类的新物种分布信息。拖钓捕获的四种鱼类包括东方狐鲣（Bonito，Sarda orientalis）、南方蓝鳍金枪鱼（Southern bluefin tuna，Thunnus maccoyi）、长鳍金枪鱼（Albacore，Thunnus alalunga）和鲣鱼（Skipjack tuna，Katsuwonus pelamis）。本次研究测定了鱼类的体长、数量、体重及目标信号强度，并选取部分海绵物种用于分类学研究。为探究沙丁鱼（pilchard，Sardinops neopilchardus）的分布规律，开展了浮游生物观测。关于本数据集的更多信息详见本次航次总结报告（数据来源于航次报告）。- 本次航次记录的生物实地数据表已扫描为PDF格式，可供CSIRO员工在线查阅，详情请见下方“存储介质列表（Stored Media List）”中的链接。
