Partial pressure (or fugacity) of carbon dioxide, temperature, salinity and other variables collected from surface underway observations using carbon dioxide gas analyzer, shower head equilibrator and other instruments from NOAA Ship Ronald H. Brown cruise RB1205 in North Atlantic Ocean from 2012-09-02 to 2012-09-05 (NCEI Accession 0162170)

This dataset includes Surface underway, chemical, meteorological and physical data collected from NOAA Ship Ronald H. Brown Cruise RB1205 in the North Atlantic Ocean from 2012-09-02 to 2012-09-05. These data include measurements of mole fraction of CO2 in the equilibrator headspace (dry) at equilibrator temperature, mole fraction of CO2 measured in dry outside air, barometric pressure in the equilibrator headspace, barometric pressure, corrected to sea level, water temperature in equilibrator, sea surface temperature, sea surface salinity, fugacity of CO2 in sea water at SST and 100% humidity, and difference between sea water fCO2 and interpolated air fCO2. 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 Rik Wanninkhof and Denis Pierrot of NOAA Atlantic Oceanographic and Meteorological Laboratory as part of NOAA Ship Ronald H. Brown research cruise RB1205 data set. The cruise Expedition code (EXPOCODE) is 33RO20120902.

本数据集包含2012年9月2日至2012年9月5日期间，于北大西洋海域随美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration，NOAA）“罗纳德·H·布朗号”科考航次RB1205采集的水面走航、化学、气象及物理观测数据。本次采集的数据涵盖以下测量项：平衡器顶空（干燥状态）中二氧化碳（CO₂）摩尔分数（对应平衡器温度）、干燥外界空气中的CO₂摩尔分数、平衡器顶空大气压力、经海平面校正后的大气压力、平衡器内水温、海表温度、海表盐度、海表温度（Sea Surface Temperature, SST）及100%湿度条件下海水中CO₂逸度，以及海水fCO₂与插值大气fCO₂的差值。用于采集本数据集的仪器包括二氧化碳（CO₂）气体分析仪，以及用于自主CO₂测量的淋浴式腔室平衡器。本数据集由NOAA大西洋海洋与气象实验室的里克·万宁霍夫（Rik Wanninkhof）与丹尼斯·皮埃罗（Denis Pierrot），作为“罗纳德·H·布朗号”科考航次RB1205数据集的一部分完成采集。本航次的航次代码（EXPOCODE）为33RO20120902。
