Partial pressure (or fugacity) of carbon dioxide, salinity and other variables collected from Surface underway 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 Ind

NODC Accession 0117499 includes Surface underway, chemical, meteorological and physical data collected from L'ASTROLABE in the Indian Ocean, South Pacific Ocean and Tasman Sea from 2008-10-21 to 2011-03-05 and retrieved during cruise 353L20081021. These data include AIR-SEA DIFFERENCE - PARTIAL PRESSURE (OR FUGACITY) OF CARBON DIOXIDE, BAROMETRIC PRESSURE, Partial pressure (or fugacity) of carbon dioxide - atmosphere, Partial pressure (or fugacity) of carbon dioxide - water, 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_2008_2010 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登录号（NODC Accession）0117499包含2008年10月21日至2011年3月5日期间，在印度洋、南太平洋和塔斯曼海由‘ASTROLABE’号采集，并在航次353L20081021中获取的表层走航化学、气象与物理数据。该数据集涵盖气海二氧化碳分压（或逸度）差、气压、大气二氧化碳分压（或逸度）、海水二氧化碳分压（或逸度）、盐度、海表温度、风向与风速。采集此类数据所用的仪器包括二氧化碳（CO₂）气体分析仪与用于自主二氧化碳（CO₂）测量的淋浴头式平衡舱。该数据由英联邦科学与工业研究组织的布朗蒂·蒂尔布鲁克（Bronte Tilbrook）作为VOS_L_Astrolabe_2008_2010数据集的一部分采集完成。

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。来自14个国家的国际团队已为科研船与商用船舶配备自动化二氧化碳采样设备，用于分析海洋与大气间的碳交换过程。
