Southern Surveyor Voyage SS 02/97 Biological Data Overview

This record is an overview entry for biological data collected on Southern Surveyor cruise SS 02/97. This cruise took place in the Torres Strait, Gulf of Carpentaria and the Arafura Sea during 12 February - 12 March 1997, under the leadership of John Salini. Biological data collected on this cruise include vertebrate and invertebrate bycatch species in prawn trawls from nine areas of the northern prawn fishery and the Torres Strait including seven subsampling prawn trawl experiments; RoxAnn and EK500 acoustic data to help discriminate bottom environments, accompanied by dredge tows and abiotic samples; saurid specimens for phylogenetic analyses and photographic specimens of commercial fishes. 24 live sea snakes were also tested for post-trawl survival, and leiognathids (ponyfish) chemically treated for otolith marking. 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.

本元数据记录为“南方调查号”（Southern Surveyor）SS 02/97航次所采集生物数据的概览条目。该航次于1997年2月12日至3月12日期间，在托雷斯海峡、卡奔塔利亚湾与阿拉弗拉海开展，由约翰·萨利尼（John Salini）担任航次负责人。本航次采集的生物数据涵盖北部虾类渔场及托雷斯海峡共9个区域的虾拖网作业所获脊椎动物与无脊椎动物兼捕物种，包含7次虾拖网抽样实验；辅以可用于底质环境判别的RoxAnn与EK500声学数据，同步配套拖曳采泥作业数据与非生物样本；用于系统发育分析的蜥形鱼（saurid）标本及商业鱼类摄影标本。此外，还对24条活海蛇开展了拖网作业后存活率测试，并对鲾科（ponyfish）样本进行化学处理以完成耳石标记。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，对涵盖多个航次的各类独立数据类型分别进行索引。
