Courageous Cruise 046 Biological Data overview, 1979

This record describes the datasets obtained on Courageous Cruise 046. The data were obtained from the Great Australian Bight in February and March 1979. Data were obtained from acoustic and trawl surveys for pelagic and demersal fish. The dominant species in the catches included stingaree, Jackass morwong (Nemadactylus macropterus), latchet, and Chinaman leatherjacket (Navon ayraud). Length, numbers, weight and target signal strength were determined. Plankton samples were taken at intervals during the cruise. Photography of the catch from each trawl shot. In addition, approximately thirty seven 35 mm colour transparencies of unidentified, unusual or previously unphotographed fish species. 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.

本记录详述了勇敢号第046次巡航（Courageous Cruise 046）所获取的数据集。数据采集于1979年2月至3月的澳大利亚大湾（Great Australian Bight）海域，通过针对中上层鱼类与底栖鱼类的声学调查及拖网调查获取。渔获物中的优势物种包括刺魟（stingaree）、驴突吻鲈（Nemadactylus macropterus）、棘鲂鮄（latchet）以及中华革鲀（Navon ayraud）。本次调查测定了渔获的体长、个体数量、体重及目标信号强度。巡航期间按固定间隔采集浮游生物样本，并对每一次拖网下网作业的渔获物进行摄影记录。此外，还拍摄了约37张35毫米彩色正片（幻灯片），内容为未鉴定、罕见或此前未被影像记录的鱼类物种。本数据集的补充信息载于本次航行的巡航总结报告（源自巡航报告）。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，可在线供澳大利亚联邦科学与工业研究组织（CSIRO）工作人员查阅。详见下方"Stored Media List"下的详情链接。
