Aurora Australis WOCE Southern Ocean oceanographic data, cruise au9601
收藏资源简介:
Oceanographic measurements were conducted along WOCE Southern Ocean meridional section SR3 between Tasmania and Antarctica from August to September 1996. A total of 71 CTD vertical profile stations were taken, most to near bottom. Over 1500 Niskin bottle water samples were collected for the measurement of salinity, dissolved oxygen, nutrients (phosphate, nitrate+nitrite, silicate), dissolved inorganic carbon, alkalinity, carbon isotopes, primary productivity, and biological parameters, using a 24 bottle rosette sampler. Measurement and data processing techniques are summarised, 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 depthpressuretemperature (T-90)salinitysigma-Tspecific volume anomalygeopotential anomalydissolved oxygenfluorescencephotosynthetically active radiation
1996年8月至9月,科研团队在塔斯马尼亚与南极洲之间的世界海洋环流实验(WOCE)南大洋经向断面SR3上开展了海洋学观测作业。本次作业共布设71个温盐深仪(CTD)垂直剖面测站,多数测站的观测深度可达近海底。研究采用24瓶式采水笼(rosette sampler)搭载尼斯金采水器(Niskin bottle),共采集超过1500份水样,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、碱度、碳同位素、初级生产力及生物学参数。本数据集总结了观测与数据处理技术,并以图表形式呈现了数据汇总结果。本数据集包含以下字段:海洋学(oceanography)、观测船(ship)、测站编号(station number)、日期(date)、开始时间(start time)、海底时间(bottom time)、结束时间(finish time)、航次(cruise)、起始位置(start position)、海底位置(bottom position)、终止位置(finish position)、最大位置(maximum position)、海底水深(bottom depth)、压力(pressure)、温度(T-90)、盐度(salinity)、密度Sigma-T(sigma-T)、比容异常(specific volume anomaly)、位势异常(geopotential anomaly)、溶解氧(dissolved oxygen)、荧光(fluorescence)、光合有效辐射(photosynthetically active radiation)
