Partial pressure (or fugacity) of carbon dioxide, salinity and other variables collected from Surface underway observations using Barometric pressure sensor, Carbon dioxide (CO2) gas analyzer and other instruments from the RONALD H. BROWN in the South Pacific Ocean from 2014-02-25 to 2014-03-13 (NO

NODC Accession 0117674 includes Surface underway, chemical, meteorological and physical data collected from RONALD H. BROWN in the South Pacific Ocean from 2014-02-25 to 2014-03-13 and retrieved during cruise 33RO20140225. 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 and SEA SURFACE TEMPERATURE. The instruments used to collect these data include Barometric pressure sensor, Carbon dioxide (CO2) gas analyzer, Shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement and thermosalinographs. These data were collected by Rik Wanninkhof of US DOC; NOAA; OAR; Atlantic Oceanographic and Meteorological Laboratory as part of the R/V_Ronald_Brown_2014_RB1401 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）存档编号0117674包含2014年2月25日至2014年3月13日期间，于南太平洋“罗纳德·H·布朗号（RONALD H. BROWN）”科考船上采集的走航表层观测、化学、气象与物理数据，数据采集航次为33RO20140225。此类数据涵盖海-气二氧化碳分压（或逸度）差值、气压、大气二氧化碳分压（或逸度）、海水二氧化碳分压（或逸度）、盐度以及海表温度。用于采集这些数据的仪器包括：气压传感器、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，以及温盐观测仪（thermosalinograph）。这些数据由美国商务部（United States Department of Commerce, US DOC）下属的美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）、海洋与大气研究局（Oceanic and Atmospheric Research, OAR）、大西洋海洋气象实验室的里克·万宁霍夫（Rik Wanninkhof）作为“R/V_Ronald_Brown_2014_RB1401”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。来自14个国家的国际团队已为科研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。
