Partial pressure (or fugacity) of carbon dioxide, salinity and other variables collected from underway - surface observations using Barometric pressure sensor, Carbon dioxide (CO2) gas analyzer and other instruments from the KEIFU MARU in the East China Sea (Tung Hai), North Pacific Ocean and other

NODC Accession 0081044 includes chemical, meteorological, physical and underway - surface data collected from KEIFU MARU in the East China Sea (Tung Hai), North Pacific Ocean, Philippine Sea and South Pacific Ocean from 2001-01-20 to 2011-03-22 and retrieved during cruise 49FA20010120. These data include BAROMETRIC PRESSURE, CARBON DIOXIDE - AIR, Partial pressure (or fugacity) of carbon dioxide, SALINITY and SEA SURFACE TEMPERATURE. The instruments used to collect these data include Barometric pressure sensor, Carbon dioxide (CO2) gas analyzer and Shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement. These data were collected by Akira Nakadate and Shu Saito of Japan Meteorological Agency; Pollutants Chemical Analysis Center; Marine Division; Global Environment and Marine Depertment as part of the VOS R/V Keifu Maru Lines 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.国家海洋数据中心（National Oceanographic Data Center, NODC）馆藏编号0081044的数据集，涵盖2001年1月20日至2011年3月22日期间，由“开复丸（KEIFU MARU）”在东海（Tung Hai，威妥玛拼音旧称）、北太平洋、菲律宾海及南太平洋采集的化学、气象、物理及走航表层观测数据，该批数据于航次49FA20010120期间获取。本数据集包含气压（BAROMETRIC PRESSURE）、大气二氧化碳（CARBON DIOXIDE - AIR）、二氧化碳分压（或逸度）（Partial pressure (or fugacity) of carbon dioxide）、盐度（SALINITY）及海表温度（SEA SURFACE TEMPERATURE）五类观测参数。采集上述数据所用的仪器包括气压传感器、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式腔室平衡器（Shower head chamber equilibrator）。该数据集由日本气象厅（Japan Meteorological Agency）、污染物化学分析中心、海洋部门及全球环境与海洋部的Akira Nakadate与Shu Saito完成采集，作为“志愿观测船（Volunteer Observing Ship, VOS）开复丸航线数据集”的组成部分。全球志愿观测船（Global Volunteer Observing Ship, VOS）计划由联合国教科文组织国际海洋碳协调项目（UNESCO 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船与商用船舶配备自动化二氧化碳采样设备，用以分析海洋与大气间的碳交换过程。
