OCD200201. FV Ocean Dawn ES60 Acoustic Data

38kHz Simrad ES60 acoustic data collected during commercial fishing of spawning blue grenadier off the Tasmanian west coast in 2002. FV Ocean Dawn was one of three factory freezer vessels collection acoustic and biological data as part of a FRDC project. Acoustic data is held by the CSIRO Marine Science Acoustic Group (Hobart). Additional data: gps embedded in ES60 .raw files, AMFA (Australian Fisheries Mangement Authority) observer biological data (species, length, weight, sex, stage)(contact AFMA Observer section), AFMA trawl shot log - filled in by ships officers for each trawl shot, showing catch, location etc (contact AFMA Observer section). Complementary data sets as per above collected by vessels FV Aoraki and FV Petersen during the 2002 season. ES60 history files only. No cruise track or digitised echogram data available. Note cruise dates here indicate the period for which we hold data. This is a subset of the voyage duration. The actual start/end dates of this voyage are not known. This information is probably in the trawl log sheets of which we have copies.

本数据集包含2002年于塔斯马尼亚西海岸外海域针对产卵期蓝鳕（blue grenadier）开展的商业捕捞作业所采集的38kHz Simrad ES60声学数据。
渔船FV Ocean Dawn是参与渔业研究与发展公司（Fisheries Research and Development Corporation, FRDC）项目的3艘工厂冷冻渔船之一，负责采集声学与生物学数据。该声学数据由霍巴特的澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation, CSIRO）海洋科学声学研究组保管。
附加数据包括：嵌入ES60设备生成的.raw文件中的全球定位系统（Global Positioning System, GPS）数据；澳大利亚渔业管理局（Australian Fisheries Management Authority, AFMA）观察员采集的生物学数据（涵盖物种、体长、体重、性别、发育阶段），相关咨询可联系AFMA观察员部门；AFMA拖网作业日志——由船舶船员针对每一次拖网作业填写，记录了渔获量、作业位置等信息，相关咨询可联系AFMA观察员部门。
2002年作业季期间，渔船FV Aoraki与FV Petersen亦采集了符合上述标准的配套数据集，仅包含ES60相关历史文件，无航迹或数字化回声图数据可供获取。
请注意：此处标注的航次日期仅代表本机构持有数据的时间段，仅为整个航次时长的子集。该航次的实际起止日期暂不可考，相关信息大概率留存于我们已获取副本的拖网作业日志中。
