Southern Surveyor Voyage SS 03/91 Biological Data Overview

This record is an overview entry for biological data collected on Southern Surveyor cruise SS 03/91. This cruise took place in the Great Australian Bight (transect south of Tasmania to Cape Leeuwin, WA) and off the west coast of Australia during 23 August - 10 September 1991, under the leadership of Don McKenzie and Bruce Phillips. Biological data collected on this cruise include puerulus and phyllosoma larvae samples from the continental shelf and slope in the vicinity of the Abrolhos Islands, in relation to the Leeuwin Current. Hydrographic sections were also carried out with the CTD across the Leeuwin Current. 45 XBTs were dropped on the transect from south of Tasmania to Cape Leeuwin at approximately 30 nm intervals and at each drop seawater samples were collected and frozen for subsequent analysis for phosphate, nitrate and silicate. Thirty salinity samples were collected and twelve samples were filtered for estimation of chloraphyll a. Please note: This metadata record is a preliminary entry derived from information in the cruise plan and/or cruise report. Individual data types - which may span several cruises - will be indexed separately within this metadata system in due course. - 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"南方考察号（Southern Surveyor）"SS 03/91航次采集的生物学数据概述条目。本次航次于1991年8月23日至9月10日期间实施，作业海域涵盖大澳大利亚湾（Great Australian Bight，塔斯马尼亚南部至西澳大利亚州卢因角断面）及澳大利亚西海岸附近海域，由唐·麦肯齐（Don McKenzie）与布鲁斯·菲利普斯（Bruce Phillips）领衔主持。本次航次采集的生物学数据包含阿布洛霍斯群岛（Abrolhos Islands）周边大陆架与陆坡区域的龙虾幼体后期（puerulus）及叶状幼体（phyllosoma larvae）样本，相关研究围绕卢因海流（Leeuwin Current）展开。本次航次同步使用温盐深仪（CTD）开展卢因海流断面的水文观测；在塔斯马尼亚南部至卢因角的断面上，以约30海里的间隔投放了45台抛弃式温深仪（XBT），每投放一次即采集海水样本并冷冻保存，用于后续磷酸盐、硝酸盐及硅酸盐的含量分析。本次航次共采集30份盐度样本，并对12份样本进行过滤以测定叶绿素a（chlorophyll a）含量。请注意：本元数据记录为基于航次计划及/或航次报告信息形成的初步条目。后续将在本元数据系统内，对跨多个航次的各类数据类型分别进行索引编目。- 本次航行期间记录的生物学野外数据记录表（Biological Field Data Sheets）已扫描为PDF格式，仅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"存储介质列表（Stored Media List）"下的详情链接。
