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 Ryofu Maru in the East Chi

NCEI Accession 0116981 includes Surface underway data collected from Ryofu Maru in the East China Sea (Tung Hai), North Pacific Ocean, Philippine Sea, Sea of Japan and South Pacific Ocean from 1995-07-16 to 1999-11-05. These data include BAROMETRIC PRESSURE, Partial pressure (or fugacity) of carbon dioxide - atmosphere, Partial pressure (or fugacity) of carbon dioxide - water, SALINITY and SEA SURFACE TEMPERATURE. The instruments used to collect these data include Carbon dioxide (CO2) gas analyzer, Shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement, not applicable and thermosalinographs.

These data were collected by Shu Saito and Akira Nakadate of Japan Meteorological Agency; Pollutants Chemical Analysis Center; Marine Division; Global Environment and Marine Department as part of the VOS_Ryofu_Maru_1995_1999 data set. CDIAC associated the following cruise ID(s) with this data set: 49UP19950716

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.

美国国家环境信息中心（National Centers for Environmental Information, NCEI）存档编号0116981包含1995年7月16日至1999年11月5日期间，在东海（Tung Hai）、北太平洋、菲律宾海、日本海及南太平洋海域由"Ryofu Maru"号采集的水面走航观测数据。该数据集涵盖气压（BAROMETRIC PRESSURE）、大气二氧化碳分压（或逸度）、水体二氧化碳分压（或逸度）、盐度（SALINITY）以及海表温度（SEA SURFACE TEMPERATURE）。用于采集此类数据的仪器包括：二氧化碳（CO2）气体分析仪、用于自主二氧化碳测量的淋浴头式平衡舱、无对应仪器项以及温盐观测仪（thermosalinographs）。

此类数据由日本气象厅斋藤修（Shu Saito）、中寺明（Akira Nakadate），以及污染物化学分析中心、海洋部、全球环境与海洋部门作为VOS_Ryofu_Maru_1995_1999数据集的组成部分采集完成。美国碳数据信息中心（Carbon Dioxide Information Analysis Center, CDIAC）为该数据集关联了以下航次编号：49UP19950716。

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（UNESCO 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舶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。
