Aurora Australis Voyage 1 (WANDER) 1997-98 Underway Data

This dataset contains the underway data from Voyage 1 1997-98 (WANDER) of the Aurora Australis. This was a manned marine science cruise. This is the first AA voyage to use the new Java-based NOODLES logging system. See the Voyage Leader's, Marine Science Support Data Quality and Programmer's Reports at the Related URL section.CTD and XBT data were also obtained on this voyage.From the Voyage Leader's Report:RSV Aurora Australis came on charter for the 51st ANARE and the first voyage of the 1997-98 season on 8 September, and sailed from Selfs Point for Macquarie Island at 2100 on the 9th. The vessel anchored in Buckles Bay at 0810 on 13 September after a moderately rough passage that included the conducting of a test CTD. The approach (and departure) route conformed with a request from ANAREMAIC to cover areas devoid of bathymetric cover.Four IRBs transferred expeditioners and cargo. Three of the boats were crewed by station personnel - the fourth by Andrew McEldowney and Jon Reeve. Operations were completed at 1430. Among the more unusual RTA items backloaded was a racing pigeon that had flown from Devonport to the island three weeks earlier.On leaving Macquarie Island, the vessel headed west to 54 S, 141 30 E, the site of the first of give SubAntarctic Zone Oceanography (SAZ) moorings to be deployed on the cruise (au9701). The passage was rough and the vessel's resulting slow progress generated concern that there would be insufficient time to deploy all the SAZ moorings and RTA on the specified date. A few of the 1000m CTDs originally scheduled for every degree of latitude were omitted in order to ensure that sufficient time would be available for the final moorings. Both engines were engaged to make up time between stations, and contingency planning allowed for the repositioning of the final mooring closer to Hobart, at 42 S instead of 43. This relocation proved unnecessary as the time allocated in the shipping schedule for the moorings and bathymetric surveys of each site proved to be unusually generous.本数据集收录了南极光号（Aurora Australis）1997-1998年度第1航次（代号WANDER）的走航观测数据。本次航次为载人海洋科学考察航次，亦是该船首次采用基于Java的NOODLES日志系统的航次。相关链接板块收录了航次负责人报告、海洋科学支持数据质量报告以及程序员报告。本次航次同时采集了温盐深测量仪（CTD）与抛弃式温盐深剖面仪（XBT）数据。 据航次负责人报告：南极光号科考补给船于1997年9月8日正式为第51届澳大利亚国家南极研究探险队（ANARE）执役，作为1997-1998年度的首航次，并于9月9日21时从塞尔夫斯角启航前往麦夸里岛。船舶在经历一段较为颠簸的航程（期间完成了CTD测试作业）后，于9月13日08时10分在巴克尔湾抛锚。其进港及离港航线符合澳大利亚国家南极研究探险队海洋信息中心（ANAREMAIC）提出的覆盖无水深测量覆盖区域的要求。 4艘充气工作艇（IRB）完成了科考队员与物资的转运作业，其中3艘艇由站务人员操作，第4艘艇由安德鲁·麦克埃尔杜（Andrew McEldowney）与乔恩·里夫（Jon Reeve）操控，全部转运作业于14时30分完成。本次返航装载的特殊物资中，包含一只三周前从德文波特飞抵该岛的赛鸽。 离开麦夸里岛后，船舶向西航行至南纬54度、东经141°30′海域，此处为本航次将部署的五套亚南极区海洋学（SAZ）锚系设备中的首套布设点位（编号au9701）。此次航行海况恶劣，船舶航速缓慢，导致团队担忧无法在指定日期前完成全部SAZ锚系设备与返航物资（RTA）的布设作业。原计划按每纬度间隔布设的1000米级CTD中，有部分测点被取消，以确保有足够时间完成最后一批锚系设备的布设。船舶启用双引擎以在测点之间抢回时间，同时应急预案允许将最后一套锚系设备的布设点位调整至更靠近霍巴特的南纬42度处，而非原定的南纬43度。但此次点位调整最终并无必要，因为航运日程中为各点位锚系设备布设与水深测量预留的时间异常充裕。
