Ka'imimoana
The CO2 group at PMEL gathered surface pCO2 measurements on board the NOAA Ship Ka'imimoana from 1996 through 2010 as a companion project to the biannual servicing of the Tropical Atmosphere Ocean (TAO) Array moorings. Each cruise generally occupied two of the TAO Lines: 165°E and 180°, 170°W and 155°W, 140°W and 125°W,° 110°W and 95°W. The cruises during the 15-year period included 77 transects of the equatorial Pacific between 95°W and 165°E, and spanned several El Niño events.
Data can be accessed from the National Centers for Environmental Information (NCEI) and from the Surface Ocean CO2 Atlas (SOCAT)
