Aurora Australis marine science cruise au0103 (CLIVAR_SR3) - CTD and ADCP data

Oceanographic measurements were conducted along CLIVAR Southern Ocean meridional repeat transect SR3 between Tasmania and Antarctica from October to December 2001. A total of 135 CTD vertical profile stations were taken, more than half to within 20 m of the bottom. Over 2200 Niskin bottle water samples were collected for the measurement of salinity, dissolved oxygen, nutrients, CFC's, CCl4, dissolved inorganic carbon, alkalinity, 13C, DMS/DMSP/DMSO, halocarbons, barium, barite, ammonia, del30Si, dissolved and particulate organic carbon, particulate silica, 15N-nitrate, 18O, 234Th, 230Th, 231Pa, primary productivity and biological parameters, using a 24 bottle rosette sampler. Near surface current data were collected using a ship mounted ADCP. Two sediment trap moorings were serviced, and a third mooring was deployed at a new location. A summary of all CTD data and data quality is presented in the data report.This work was completed as part of ASAC project 1335.

2001年10月至12月，研究团队在塔斯马尼亚与南极洲之间的CLIVAR（气候变率与可预报性研究计划）南大洋经向重复断面SR3沿线开展海洋学观测。本次观测共完成135个CTD（温盐深仪，Conductivity-Temperature-Depth）垂直剖面测站，其中超半数测站的站位水深距海底不足20米。采用24瓶式罗塞塔采样器，采集了2200余个经尼斯金采水器获取的水样，用于测定盐度、溶解氧、营养盐、氯氟烃（CFCs）、四氯化碳（CCl₄）、溶解无机碳、碱度、碳13（¹³C）、二甲基硫/二甲基巯基丙酸内盐/二甲基亚砜（DMS/DMSP/DMSO）、卤代烃、钡、重晶石、氨、δ³⁰Si、溶解态与颗粒态有机碳、颗粒态硅、¹⁵N标记硝酸盐、氧18（¹⁸O）、钍234（²³⁴Th）、钍230（²³⁰Th）、镤231（²³¹Pa）、初级生产力及生物学参数。采用船载ADCP（声学多普勒流速剖面仪，Acoustic Doppler Current Profiler）采集近表层海流数据。对两套沉积物捕获器锚系进行维护作业，并在新站位部署了第三套锚系。所有CTD数据及数据质量汇总情况已在数据报告中刊载。本研究作为ASAC项目1335的一部分完成。
