Partial pressure (or fugacity) of carbon dioxide, salinity and other variables collected from underway - surface observations using Barometric pressure sensor, Carbon dioxide (CO2) gas analyzer and other instruments from the EXPLORER OF THE SEAS in the Caribbean Sea, Gulf of Mexico and North Atlant

NODC Accession 0081033 includes biological, chemical, meteorological, physical and underway - surface data collected from EXPLORER OF THE SEAS in the Caribbean Sea, Gulf of Mexico and North Atlantic Ocean from 2004-01-03 to 2005-01-02 and retrieved during cruise EX0401 - EX0452. These data include AIR TEMPERATURE, BAROMETRIC PRESSURE, CARBON DIOXIDE - AIR, CARBON DIOXIDE - PARTIAL PRESSURE - DIFFERENCE, DISSOLVED OXYGEN, FLUORESCENCE, Partial pressure (or fugacity) of carbon dioxide, SALINITY, SEA SURFACE TEMPERATURE, WIND DIRECTION and WIND SPEED. 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 VOS Explorer of the Seas Lines 2004 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）登录号0081033收录了2004年1月3日至2005年1月2日期间，由“海洋探索者号（EXPLORER OF THE SEAS）”在加勒比海、墨西哥湾及北大西洋海域采集的生物、化学、气象、物理及走航表层数据，相关航次编号为EX0401至EX0452。该数据集涵盖的观测指标包括：气温、气压、空气中二氧化碳浓度、二氧化碳分压差值、溶解氧、荧光强度、二氧化碳分压（或逸度）、盐度、海表温度、风向及风速。用于采集上述数据的仪器包括：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，以及温盐仪。该批数据由美国商务部（United States Department of Commerce, US DOC）、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（Office of Oceanic and Atmospheric Research, OAR）及大西洋海洋气象实验室的里克·万宁霍夫（Rik Wanninkhof）采集，作为2004年“海洋探索者号志愿观测船航线”数据集的组成部分。

全球志愿观测船（Global 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）统筹实施。来自14个国家的国际团队已为科研船舶及商业商船配备自动化二氧化碳采样设备，用于开展海洋与大气间碳交换过程的观测分析。
