Aurora Australis Southern Ocean oceanographic data, cruise au1121 2010/11 VMS

Oceanographic measurements were collected aboard Aurora Australis cruise au1121, voyage "Marine Science" (i.e. voyage 2.1) 2010/2011, from 4th January to 6th February 2011.The cruise commenced with a full north to south occupation of the CLIVAR/WOCE meridional repeat section SR3, followed by work around the Antarctic continental margin in the region of the Adelie Depression and the former Mertz Glacier ice tongue.A total of 149 CTD vertical profile stations were taken on the cruise, most to within 15 metres of the bottom. Over 2000 Niskin bottle water samples were collected for the measurement of salinity, dissolved oxygen, nutrients (phosphate, nitrate+nitrite and silicate), oxygen-18, dissolved inorganic carbon (i.e. TCO2), alkalinity, pH, helium, tritium, and biological parameters, using a 24 bottle rosette sampler. Upper water column current profile data were collected by a ship mounted ADCP. Meteorological and water property data were collected by the array of ship's underway sensors. An array of 3 bottom mounted ADCP moorings were deployed near the Adelie Depression, for recovery in the 2012/13 season.Underway data were also collected on this voyage, and are linked to this metadata record at the provided URL. A detailed readme is available as part of the download.Finally, ADCP (Acoustic Doppler Current Profiler) data are also linked, and are in Matlab format.

海洋学测量数据采集于2010/2011年度“海洋科学”航次（即2.1航次）的极光号（Aurora Australis）科考船au1121航段，时间为2011年1月4日至2月6日。

该航段首先完成了CLIVAR/WOCE子午重复断面SR3的全程南北向观测，随后在阿德利海盆（Adelie Depression）及原默茨冰川冰舌区域的南极大陆边缘开展工作。

航段共完成149个CTD（温盐深仪，Conductivity-Temperature-Depth）垂直剖面站位观测，大部分站位接近海底15米范围内。使用24瓶玫瑰花采样器采集了超过2000个尼斯金瓶（Niskin bottle）水样，用于测定盐度、溶解氧、营养盐（磷酸盐、硝酸盐+亚硝酸盐及硅酸盐）、氧-18、溶解无机碳（即总二氧化碳，TCO2）、碱度、pH值、氦、氚及生物参数。上层水柱流场剖面数据由船载声学多普勒流速剖面仪（ADCP，Acoustic Doppler Current Profiler）采集。气象及水体性质数据由船载走航传感器阵列采集。在阿德利海盆附近布放了3套坐底式ADCP锚系，计划于2012/13年度回收。

本航次还采集了走航数据，相关数据可通过提供的URL链接至本元数据记录。下载内容中包含详细的说明文档（readme）。

最后，ADCP数据也已关联，格式为Matlab。
