Soela Voyage SO 4/86 Biological Data Overview

This record is an overview entry for biological data collected on Soela cruise SO 4/86. This cruise took place in waters to the and east and north of Tasmania in two legs. Leg 1 from 8 - 17 July, and Leg 2 from 18 - 28 July 1986, under the leadership of F. R. Harden Jones. Aims:,br> Part 1 1. To carry out exploratory and experimental fishing in eastern and western waters of Tasmania, with particular reference to canyons, gullies, slopes, banks, sea mounts and depths of 1300 - 1500 m, making use of demersal and pelagic trawls, droplines and traps as in cruise 3/86. Particular attention will be given to handling of the catch. Part 2 1. To sample icthyop1ankton on the east coast of Tasmania and south east coast of New South Wales. 2. If blue grenadier larvae are found in the ichthyoplankton, to sample the adults of the species and to attempt artificial fertilisations. 3. To continue with the exploratory and experimental fishing studies on an opportunistic basis. 4. a. To collect water samples from approximately five stations. The samples collected will be from depths between the surface and 1000 meters and will be analysed for nutrients both total and dissolved forms. b. To collect water from a yet to be determined depth (less than 1000 meters) for storage experiments to be carried out over the following two years. c. To determine a horizontal nutrient profile in surface water from Storm Bay to Princess Wharf. The results to be correlated with underway temperature, salinity and fluorescence results.(derived from the cruise plan).(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.

Harden Jones）主持。 航次目标分为两部分： 第一部分 1. 在塔斯马尼亚东西部海域开展探索性与试验性捕捞作业，重点关注峡谷、海沟、斜坡、浅滩、海山及1300~1500米水深区域，沿用航次3/86所用的底拖网（demersal trawl）、中层拖网（pelagic trawl）、延绳钓及陷阱渔笼等装备，并特别注重渔获物的处理流程。 第二部分 1. 在塔斯马尼亚东海岸及新南威尔士州东南海岸采集鱼类浮游生物（ichthyoplankton）样本。 2. 若在鱼类浮游生物样本中发现蓝无须鳕（blue grenadier）仔鱼，则对该物种的成体进行采样，并尝试开展人工授精实验。 3. 以机会性采样为原则，持续推进探索性与试验性捕捞研究。 4. a. 于约5个站位采集水样，采样深度覆盖表层至1000米，将对样本中的总态及溶解态营养盐进行分析。 b. 采集深度尚未确定（小于1000米）的水样，用于未来两年开展的储存实验。 c. 测定从风暴湾（Storm Bay）至公主码头（Princess Wharf）的表层海水水平营养盐分布剖面，并将结果与航行途中获取的温度、盐度及荧光数据进行关联分析。 本概述基于航次计划及航次报告编制。本航次期间记录的生物野外数据记录表已扫描为PDF格式，仅可通过在线渠道供澳大利亚联邦科学与工业研究组织（CSIRO）职员查阅，详见下方“存储介质列表”下的详情链接。
