Aurora Australis WOCE Southern Ocean oceanographic data, cruise au9407

Oceanographic measurements were conducted in January 1994 (on voyage 7 of the 1993/1994 summer season) along WOCE Southern Ocean meridional section SR3 between Tasmania and Antarctica, and along a northward section lying between 82 and 86 deg.E and crossing the Princess Elizabeth Trough. Additional measurements were made at mooring locations, and at a time series station. A total of 102 CTD vertical profile stations were taken, most to near bottom. Over 2000 Niskin water bottle samples were collected for the measurement of salinity, dissolved oxygen, nutrients (phosphate, nitrate+nitrite, silicate), dissolved inorganic and organic carbon, carbon 13, dimethyl sulphide/dimethyl sulphoniopropionate, iodate/iodide, and biological parameters, using a 24 bottle rosette sampler. Measurement and data processing techniques are described, and a summary of the data are presented in graphical and tabular form.The fields in this dataset are:oceanographyshipstation numberdatestart timebottom timefinish timecruisestart positionbottom positionfinish positionmaximum positionbottom depthpressuresigma-Ttemperature (C) (ITS-90)salinity (PSS78)density-1000 (kg.m-3)specific volume anomaly x 108geopotential anomalydissolved oxygen (mmol.l-1)number of data points used in the 2 dbar averaging binstandard deviation of temperature values in the 2 dbar binstandard deviation of conductivity values in the 2 dbar binfluorescencephotosynthetically active radiationCTD pressure (dbar)CTD temperature (C) (ITS-90)reversing thermometer temperature (C)CTD conductivity (mS.cm-1)CTD salinity (PSS78)bottle salinity (PSS78)bottle quality flag (-1=rejected, 0=suspect, 1=good)niskin bottle number

本数据集于1994年1月（对应1993/1994夏季航季的第7航次）开展海洋学测量，测量航线涵盖WOCE（World Ocean Circulation Experiment，世界海洋环流实验）南大洋经向断面SR3（塔斯马尼亚与南极洲之间），以及位于东经82°至86°之间、横穿伊丽莎白公主海槽（Princess Elizabeth Trough）的北向断面。此外还在锚定观测站位及时间序列观测站开展了补充测量。本次调查共布设102个CTD（Conductivity, Temperature, Depth，温盐深仪）垂直剖面站位，多数站位的测量深度近达海底。采用24瓶式采水器组（rosette sampler）采集了超过2000个尼斯金采水瓶（Niskin water 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、硅酸盐）、溶解无机碳与溶解有机碳、碳-13、二甲基硫/二甲基巯基丙酸内盐、碘酸盐/碘化物以及生物学参数。本数据集对测量与数据处理技术进行了说明，并以图表形式呈现数据汇总结果。
