OCD200203. 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.

2002年在塔斯马尼亚西海岸外对产卵蓝鳕鱼开展商业捕捞期间，采集了38kHz Simrad ES60声学数据。FV Ocean Dawn号是参与FRDC项目的三艘工厂冷冻船之一，负责采集声学与生物数据。声学数据由CSIRO海洋科学声学组（霍巴特）持有。附加数据包括：嵌入ES60 .raw文件中的全球定位系统（GPS）数据、澳大利亚渔业管理局（AMFA，Australian Fisheries Management Authority）观察员生物数据（物种、体长、体重、性别、发育阶段）（请联系AMFA观察员部门）、AMFA拖网作业日志——由船员为每次拖网作业填写，记录渔获量、位置等信息（请联系AMFA观察员部门）。2002渔季期间，FV Aoraki号与FV Petersen号亦采集了上述补充数据集。本数据集仅包含ES60历史文件，无巡航轨迹或数字化回声图数据可用。请注意，此处所列巡航日期仅对应我们持有的数据时间段，为整个航行周期的子集。该航行的实际起止日期尚未明确，相关信息或可在我们持有的拖网作业日志副本中查询。
