Aurora Australis Voyage V1 2007/08 (SIPEX) Track and Underway Data

This dataset contains the underway data collected during the Aurora Australis Voyage V1 2007/08 (SIPEX).This voyage began in Hobart, and travelled to the ice edge where a large number of scientific observations were collected.Underway (meteorological) data are available online via the Australian Antarctic Division Data Centre web page (or via the Related URL section).See also other SIPEX metadata records.From the voyage leader's report:The Sea Ice Physics and Ecosystem eXperiment (SIPEX) was a multi-disciplinary science program focused on sea ice research in the region 115-130 E. There were 7 approved AAS proposals undertaken during the voyage:AAS 2901: PI: Dr Tony Worby (20 people)AAS 2767: PI: Klaus Meiners (18 people)AAS 2752: PI: Peter Ralph (2 people)AAS 2210: PI: Kelvin Michael (2 people)AAS 2100: PI: Graham Jones (2 people)AAS 1307: PI: Andrew McMinn (2 people)AAS 472: PI: Graham Hosie (1 person)The objectives of the voyage were to investigate the relationships between the physical sea ice environment and the sea ice biology, in particular the presence of algae and krill under the ice. A range of new instruments and techniques were used, including for the first time, radar and laser altimetry from helicopter for measuring the snow thickness and freeboard height above sea level. An instrumented Remotely Operated Vehicle (ROV) was used for making upward measurements of sea ice thickness and biomass concentration directly under the ice and a Surface and Under Ice Trawl (SUIT) was used for catching krill under the ice, clear of the ship's wake.

本数据集包含2007/2008年度极光号（Aurora Australis）V1航次（海冰物理与生态实验，SIPEX，Sea Ice Physics and Ecosystem eXperiment）期间采集的走航观测数据。本次航次从霍巴特起航，前往海冰边缘区域并在此开展了大量科学观测工作。走航（气象）数据可通过澳大利亚南极局（Australian Antarctic Division）数据中心官网或相关链接板块在线获取，亦可查阅其他SIPEX元数据记录。

根据航次领队报告：海冰物理与生态实验（SIPEX）是一项多学科科学研究计划，聚焦于东经115°至130°海域的海冰研究。本航次共获批实施7项澳大利亚南极局（AAS）研究项目：
1. AAS 2901：项目负责人为托尼·沃比博士，团队规模20人
2. AAS 2767：项目负责人克劳斯·迈纳斯，团队规模18人
3. AAS 2752：项目负责人彼得·拉尔夫，团队规模2人
4. AAS 2210：项目负责人凯文·迈克尔，团队规模2人
5. AAS 2100：项目负责人格雷厄姆·琼斯，团队规模2人
6. AAS 1307：项目负责人安德鲁·麦克明，团队规模2人
7. AAS 472：项目负责人格雷厄姆·霍西，团队规模1人

本次航次的核心目标为探究海冰物理环境与海冰生物群落之间的相互关系，尤其聚焦于冰下藻类与磷虾的分布特征。本次航次应用了一系列新型仪器与观测技术，其中首次采用直升机搭载雷达与激光测高仪，完成积雪厚度与海面以上冰面干舷高度的测量工作。本航次还搭载了集成观测仪器的遥控水下机器人（Remotely Operated Vehicle, ROV），用于直接在冰下向上采集海冰厚度与生物量浓度数据；同时使用冰下表面拖网（Surface and Under Ice Trawl, SUIT）在远离船体尾流的冰下区域捕捞磷虾。
