Partial pressure (or fugacity) of carbon dioxide, temperature, salinity and other variables collected from the coastal surface underway observations using carbon dioxide gas analyzer, shower head equilibrator and other instruments from R/V Henry B. Bigelow in the North Atlantic Ocean, US North-East

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 the NOAA Ship Henry B. Bigelow. The Bigelow primarily operates in the North Atlantic Ocean between North Carolina and Maine.
NCEI Accession 0162290 includes Surface underway, chemical, meteorological and physical data collected from NOAA Ship R/V Henry B. Bigelow in the North Atlantic Ocean, US North East coast from 2017-02-11 to 2017-04-06. 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 US DOC; NOAA; OAR; Atlantic Oceanographic and Meteorological Laboratory as part of the Henry B. Bigelow research coastal cruises HB1701, HB1702-Leg1,
HB1702-Leg2, data set. The cruise Expedition codes (EXPOCODE) are 33HH20170211, 33HH20170306, 33HH20170328.

2011年2月，美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）下属大西洋海洋与气象实验室（Atlantic Oceanographic and Meteorological Laboratory, AOML）的海洋碳研究小组，在"亨利·B·比奇洛号"科考船（NOAA Ship Henry B. Bigelow）上安装了一套用于测量表层海水与空气中二氧化碳浓度的观测仪器。该船主要作业海域为北大西洋北卡罗来纳州至缅因州之间的水域。

NCEI存档编号0162290的数据集，包含2017年2月11日至2017年4月6日期间，由"亨利·B·比奇洛号"研究船（R/V Henry B. Bigelow）在北大西洋美国东北海岸收集的走航表层水文、化学、气象与物理观测数据。本次采集的数据涵盖：平衡器顶空（干燥状态）内的二氧化碳摩尔分数（对应平衡器工作温度）、干燥外界空气中的二氧化碳摩尔分数、平衡器顶空气压、经海平面校正后的大气气压、平衡器内水温、海表温度、海表盐度、海表温度与100%湿度条件下海水中二氧化碳的逸度（fCO₂），以及海水fCO₂与插值得到的大气fCO₂之间的差值。本次数据采集所用仪器包括二氧化碳（CO₂）气体分析仪与用于自主二氧化碳测量的喷淋式舱室平衡器。

本数据集由美国商务部（United States Department of Commerce, US DOC）下属NOAA的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）负责采集，作为"亨利·B·比奇洛号"沿岸科考航次HB1701、HB1702-航段1、HB1702-航段2数据集的组成部分。本次航次的航次代码（EXPOCODE）分别为33HH20170211、33HH20170306与33HH20170328。
