Acoustic Sounder Charts from Australian Antarctic Division Voyage 6 1994/95 (BANGSS)

Acoustic sounder charts were collected at six locations during Australian Antarctic Division Voyage 6 1994/95 (BANGSS) using the Kongsberg EA200 Echo Sounder on the Aurora Australis. BANGSS is an acronym for Big ANtarctic Geological and Seismic Survey.The voyage began on 6 February 1995 and finished on 12 April 1995.Each chart is labelled with information about when and where the data was collected: date, time, latitude and longitude.The charts provide a profile of the sea floor and have a time axis with numbers in the following format.the first two digits are the daythe next two digits are the monththe next five digits are the time (UTC)the last ten digits are the maximum value on the depth axis eg 2402005 360000000500 means 24 February 5:36 UTC and the maximum value on the depth axis is 500 metres See a Related URL for a link to information about the voyage including the voyage report.

本数据集的声学测深图（Acoustic sounder charts）采集自澳大利亚南极局（Australian Antarctic Division）1994/95年度第6次航次（BANGSS）项下的6个科考站位，所用设备为搭载于南极光号（Aurora Australis）科考船的康士伯（Kongsberg）EA200回声测深仪（Echo Sounder）。BANGSS为“南极大型地质与地震调查（Big ANtarctic Geological and Seismic Survey）”的首字母缩写。本次航次于1995年2月6日启航，同年4月12日圆满完成。每张测深图均标注有数据采集的相关信息：采集日期、时间、纬度与经度。此类测深图用于呈现海底剖面形态，其时间轴采用标准化数字编码格式，规则如下：前两位数字代表日期，接下来两位代表月份，再后续五位为协调世界时（UTC）下的具体时刻，最后十位为深度轴的最大量程。示例：编码2402005 360000000500代表协调世界时2月24日5时36分，对应深度轴最大量程为500米。可通过相关链接获取本次航次的全套资料，包含航次报告。
