资源简介:
Oceanographic measurements were conducted along WOCE Southern Ocean meridional section SR3 between Tasmania and Antarctica from September to October 1991. A total of 36 CTD vertical profile stations were taken. Over 600 Niskin bottle water samples were collected for measurements of parameters including salinity, dissolved oxygen, nutrients (phosphate, nitrate+nitrite, silicate), chlorofluorocarbons, and biological parameters, using a 24 bottle rosette sampler. The fields in this dataset are: oceanography ship station number date start time bottom time finish time cruise start position bottom position finish position maximum position bottom depth pressure sigma-T temperature (C) (ITS-90) salinity (PSS78) density-1000 (kg.m-3) specific volume anomaly x 108 geopotential anomaly dissolved oxygen (mmol.l-1) number of data points used in the 2 dbar averaging bin standard deviation of temperature values in the 2 dbar bin standard deviation of conductivity values in the 2 dbar bin fluorescence photosynthetically active radiation CTD 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

1991年9月至10月,科研团队于塔斯马尼亚与南极洲之间的世界海洋环流实验(WOCE, World Ocean Circulation Experiment)南大洋子午断面SR3开展海洋学观测作业。本次航次共布设36个温盐深仪(CTD, Conductivity Temperature Depth)垂直剖面测站。研究人员采用24瓶式罗塞特采水器(rosette sampler)采集了600余组尼斯金(Niskin)采水瓶水样,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)、氯氟烃以及多项生物参数。 本数据集包含以下字段: 海洋学(oceanography)、考察船(ship)、测站编号(station number)、观测日期(date)、起始时间(start time)、底层观测时间(bottom time)、结束时间(finish time)、航次编号(cruise)、起始站位(start position)、底层站位(bottom position)、终止站位(finish position)、最大深度站位(maximum position)、海底水深(bottom depth)、压力(pressure)、西格马-T(sigma-T)、温度(℃,ITS-90温标)、盐度(PSS78实用盐标)、密度-1000(kg·m⁻³)、比容异常×10⁸、位势异常、溶解氧(mmol·L⁻¹)、2分巴(dbar)平均箱内有效数据点数量、2分巴区间内温度值的标准偏差、2分巴区间内电导率值的标准偏差、荧光强度、光合有效辐射、CTD压力(dbar)、CTD温度(℃,ITS-90温标)、颠倒温度计温度(℃)、CTD电导率(mS·cm⁻¹)、CTD盐度(PSS78实用盐标)、采水瓶盐度(PSS78实用盐标)、采水瓶质量标记(-1=弃用,0=可疑,1=合格)、尼斯金采水瓶编号(niskin bottle number)
