Soela Voyage SO 3/80 Biological Data Overview

This record is an overview entry for biological data collected on Soela cruise SO 3/80. This cruise took place in the Great Australian Bight during 26 April - 18 May 1980, under the leadership of John Stevens. Biological data collected on this cruise include EK 50 acoustic data of pelagic fish abundance. Phytoplankton filtered samples for later chlorophyll-a extraction. Fish eggs and larvae from the plankton samples. Numerous larval and juvenile cephalopods. Pilchard (27 kg) samples, the otoliths, scales and stomach contents of pilchards were retained. In the diel feeding study, Pterygotrigla polyommata occurred in every shot and preliminary results showed that 87% of this species caught in the post dawn trawl had food in their stomachs compared with 25-30% at other times.(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.

本记录为索拉号（Soela）科考航次SO 3/80所采集生物数据的概述条目。本次航次于1980年4月26日至5月18日在大澳大利亚湾开展，由约翰·史蒂文斯担任航次首席。本航次采集的生物数据包括：用于调查中上层鱼类丰度的EK 50声学数据；用于后续叶绿素a提取的浮游植物过滤样品；从浮游生物样品中分离得到的鱼卵及仔鱼；大量头足类幼体与稚体；获取了27千克的沙丁鱼样品，并留存了该批次沙丁鱼的耳石、鳞片及胃容物。在昼夜摄食研究中，每一网次均采集到棘鲂鮄（Pterygotrigla polyommata）；初步结果显示，黎明后拖网捕获的该物种个体中，87%的胃内含食物，而其他时段的这一比例仅为25%~30%。（数据源自本次航次报告）本次航行期间记录的生物实地数据表已扫描为PDF格式，仅对澳大利亚联邦科学与工业研究组织（CSIRO）员工开放在线查阅权限。详见下方「存储介质列表」下的详情链接。
