Partial pressure (or fugacity) of carbon dioxide, salinity and other variables collected from underway - surface observations using Carbon dioxide (CO2) gas analyzer, Shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement and other instruments from the L'ASTROLABE in the I

NODC Accession 0115257 includes chemical, meteorological, physical and underway - surface data collected from L'ASTROLABE in the Indian Ocean, South Pacific Ocean and Tasman Sea from 2012-01-07 to 2012-11-22 and retrieved during cruise 353L20120107, 353L20120218 and 353L20121023. These data include AIR-SEA DIFFERENCE - PARTIAL PRESSURE (OR FUGACITY) OF CARBON DIOXIDE, BAROMETRIC PRESSURE, CARBON DIOXIDE - AIR, Partial pressure (or fugacity) of carbon dioxide, SALINITY, SEA SURFACE TEMPERATURE, WIND DIRECTION and WIND SPEED. The instruments used to collect these data include Carbon dioxide (CO2) gas analyzer and Shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement. These data were collected by Bronte Tilbrook of Commonwealth Scientific and Industrial Research Organization as part of the VOS_L_Astrolabe_2012_AL1112R2, VOS_L_Astrolabe_2012_AL1112R4 and VOS_L_Astrolabe_2012_AL1213R0 data set. The Global Volunteer Observing Ship (VOS) Program is coordinated by the UNESCO International Ocean Carbon Coordination Project (IOCCP). International groups from 14 countries have been outfitting research ships and commercial vessels with automated CO2 sampling equipment to analyze the carbon exchange between the ocean and atmosphere.NODC 收录编号0115257包含2012年1月7日至2012年11月22日期间，在印度洋、南太平洋与塔斯曼海海域，由“L'ASTROLABE”号采集的化学、气象、物理及走航表层观测数据，相关航次编号为353L20120107、353L20120218及353L20121023。本次采集的数据涵盖海-气二氧化碳分压（或逸度）差值、大气压力、大气二氧化碳浓度、海水二氧化碳分压（或逸度）、海水盐度、海表温度、风向及风速。用于采集此类数据的仪器包括二氧化碳（CO₂）气体分析仪，以及用于自主二氧化碳测量的淋浴头式平衡舱（Shower head chamber equilibrator）。该数据集由澳大利亚联邦科学与工业研究组织的布朗蒂·蒂尔布鲁克作为VOS_L_Astrolabe_2012_AL1112R2、VOS_L_Astrolabe_2012_AL1112R4及VOS_L_Astrolabe_2012_AL1213R0数据集的一部分完成采集。 全球志愿观测船（Volunteer Observing Ship, VOS）计划由联合国教科文组织国际海洋碳协调项目（International Ocean Carbon Coordination Project, IOCCP）统筹协调。目前，来自14个国家的国际团队已为科研考察船与商业船舶配备自动化二氧化碳采样设备，用于分析海洋与大气之间的碳交换过程。
