Partial pressure of carbon dioxide, temperature, salinity and other variables collected from the coastal surface underway observations from NOAA Ship Henry B. Bigelow in the North Atlantic Ocean, US North-East coast in 2018 (NCEI Accession 0173357)

This dataset includes surface underway, chemical, meteorological and physical data collected from NOAA Ship Henry B. Bigelow in the North Atlantic Ocean, US North East coast in 2018. These data include measurements of mole fraction of carbon dioxide (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 fugacity of CO2 (fCO2) and interpolated air fCO2. The instruments used to collect these data include carbon dioxide gas analyzer and shower head chamber equilibrator for autonomous carbon dioxide measurement. These data were collected by Rik Wanninkhof, Denis Pierrot and Kevin Sullivan of NOAA Atlantic Oceanographic and Meteorological Laboratory as part of NOAA Ship Henry B. Bigelow research coastal cruises. In February 2011, the Ocean Carbon Group at NOAA's Atlantic Oceanographic and Meteorological Laboratory (AOML) installed an instrument to measure CO2 levels in surface water and air on NOAA Ship Henry B. Bigelow. The Bigelow primarily operates in the North Atlantic Ocean between North Carolina and Maine.

本数据集涵盖2018年于美国东北海岸外北大西洋海域，由美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）亨利·B·比奇洛号科考船（NOAA Ship Henry B. Bigelow）采集的走航表层化学、气象与物理数据。
本次采集的数据包含：平衡器温度下平衡器顶空（干燥状态）内二氧化碳（CO₂）摩尔分数、干燥外界空气中CO₂摩尔分数、平衡器顶空气压、经海平面校正后的大气压强、平衡器内水温、海表温度（Sea Surface Temperature, SST）、海表盐度、对应海表温度与100%湿度条件下海水中CO₂逸度，以及海水CO₂逸度（fCO₂）与插值大气fCO₂的差值。
本次数据采集所用仪器包括二氧化碳气体分析仪与用于自主CO₂测量的喷淋室式平衡器。
本数据集由NOAA大西洋海洋与气象实验室（Atlantic Oceanographic and Meteorological Laboratory, AOML）的里克·万宁霍夫（Rik Wanninkhof）、丹尼斯·皮埃罗（Denis Pierrot）与凯文·沙利文（Kevin Sullivan），作为亨利·B·比奇洛号科考船沿岸科考航次的一部分完成采集。
2011年2月，NOAA大西洋海洋与气象实验室（AOML）的海洋碳小组在亨利·B·比奇洛号科考船上安装了一套用于测量表层海水与大气CO₂浓度的仪器。
该科考船主要在北卡罗来纳州与缅因州之间的北大西洋海域执行科考任务。
