Antarctic Drifting Buoys

This dataset contains data from drifting buoys that are along the ice edge or frozen into the ice. The data are observed around the Australian sector of Antarctica and have been recorded since February 1985 and are ongoing. Observations exist for around 20 buoys over this area and are not continuous over this area for this time period. Data from the period 1995-1998 only have been archived.\n\nThis dataset also forms part of the International Program for Antarctic Buoys (IPAB - see the IPAB metadata record).\n\nThe data are available below via several urls below. Further information and the data can be obtained from the IPAB home page url. The data and documentation are also available directly from the NSIDC website. Finally, a copy of the data are also held locally on the Australian Antarctic Data Centre's servers.\n\nThe documentation held at the NSIDC website provides important information on interpreting the dataset. A static copy of this document is included with the local copy of the dataset held on the Australian Antarctic Data Centre's servers.\n\nThis work was also completed as part of ASAC projects 742 and 2678.\n\nThe fields in this dataset are:\nBuoy Number\nYear\nTime\nLongitude\nLatitude\nARGOS Positional Accuracy\nSea Ice Flag\nAir Pressure\nAir Temperature\nWater Temperature\nVelocity

本数据集收录了沿冰缘分布或冻嵌于海冰中的漂流浮标观测数据。观测区域覆盖南极洲澳大利亚扇形海域，观测工作自1985年2月起开展并持续至今。该区域内共获取约20套浮标的观测记录，但观测在时间与空间上均不连续，且仅1995年至1998年期间的数据完成了归档存储。

本数据集同时隶属于国际南极浮标计划（International Program for Antarctic Buoys，IPAB），详见IPAB元数据记录。

本数据集可通过下方多个链接获取。完整数据与补充说明可通过IPAB官方主页链接获取；数据及配套文档亦可直接从美国国家冰雪数据中心（National Snow and Ice Data Center，NSIDC）网站获取；此外，澳大利亚南极数据中心（Australian Antarctic Data Centre）的服务器上也留存有本数据集的本地副本。

美国国家冰雪数据中心网站上的配套文档包含了本数据集的解读关键信息，澳大利亚南极数据中心服务器上留存的数据集本地副本中，也附带了该文档的静态备份版本。

本数据集的编制工作同时依托于ASAC项目742与2678。

本数据集包含以下字段：浮标编号、观测年份、观测时间、经度、纬度、ARGOS定位精度、海冰标识、气压、气温、水温、流速。
