Courageous Cruise 034 Biological Data overview, 1978

This record describes the datasets obtained on Courageous Cruise 034. The data were obtained from the Australian NW Shelf ((North West Cape to Port Hedland areas) in May 1978. Data were obtained from acoustic and trawl surveys of pelagic and demersal fish. Predominant species included goatfish (Mullidae), threadfin bream (Nemipteridae), lizard fish (Synodontidae), scad and trevally (Carangidae), pufferfish (Tetradontidae), bigeye (Priacanthidae), emperor (Lethrinidae) and to a lesser extent sea perch (Lutjanidae). Length, numbers, weight and target signal strength were determined. Zooplankton, phytoplankton and nutrient samples were also collected from three transects. 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.

本记录介绍了勇毅号（Courageous）034航次所获取的数据集。该数据采集于1978年5月，覆盖澳大利亚西北陆架（西北角至黑德兰港海域）。数据源自中上层与底层鱼类的声学调查及拖网调查。本次调查的优势类群包括羊鱼科（Mullidae）的羊鱼、金线鱼科（Nemipteridae）的丝鳍鲷、蜥鱼科（Synodontidae）的蜥鱼、鲹科（Carangidae）的竹荚鱼与鲹类、四齿鲀科（Tetradontidae）的鲀类、大眼鲷科（Priacanthidae）的大眼鲷、裸颊鲷科（Lethrinidae）的裸颊鲷；占比相对较低的类群则包含笛鲷科（Lutjanidae）的海鲈。研究人员测定了样本的体长、个体数量、体重及目标信号强度。此外，团队还在三条调查断面上采集了浮游动物、浮游植物及营养盐样本。本数据集的补充信息详见本次航行的航次总结（资料源自航次报告）——本次航行期间记录的生物野外数据记录表已扫描为PDF格式，可供澳大利亚联邦科学与工业研究组织（CSIRO）工作人员在线查阅。相关详情可点击页面下方"Stored Media List"下的链接查看。
