Surface underway measurements of fugacity of carbon dioxide (fCO2, seawater and atmospheric), water temperature, and salinity from 3 cruises in the equatorial Pacific Ocean, collected onboard NOAA Ship Ka'imimoana in 1999 (NCEI Accession 0268311)

This dataset contains data from underway fCO2 (seawater and atmospheric), water temperature, and salinity measurements collected on 3 equatorial Pacific cruises from 1999-01-30 to 1999-07-26 as part of a ship-of-opportunity time-series. Cruise names and EXPOCODEs: KA1999_01 (33KM19990130), KA1999_02 (33KM19990506),KA1999_03 (33KM19990708). Since 1982, NOAA's Pacific Marine Environmental Laboratory has made underway CO2 observations in the equatorial Pacific as a companion project to the Global Tropical Moored Buoy Array. This effort was conducted with the support of NOAA's Global Ocean Monitoring and Observing Program.

本数据集收录了1999年1月30日至1999年7月26日期间3次赤道太平洋航次采集的走航式二氧化碳分压（underway fCO2，含海水与大气组分）、水温及盐度观测数据，相关观测属于志愿船时间序列观测项目的组成部分。各航次名称及EXPOCODE（航次代码）分别为：KA1999_01（33KM19990130）、KA1999_02（33KM19990506）、KA1999_03（33KM19990708）。自1982年起，NOAA（美国国家海洋和大气管理局）下属的太平洋海洋环境实验室便在赤道太平洋开展走航式二氧化碳观测，该项目作为全球热带系泊浮标阵列的配套工作推进。本观测工作得到了NOAA全球海洋监测与观测计划的支持。
