Total CO2, pCO2, and Total Alkalinity Data from the U.S. JGOFS Arabian Sea Process Study

Eleven cruises took place aboard the R/V Thomas G. Thompson for about sixteen months from October 1994 until January 1996. These cruises provided seasonal coverage of the annual monsoon and inter-monsoon cycles in the area southeast of Oman - from where the cruises were staged.

The monsoons of the Arabian Sea drive a uniquely intense carbon cycling system, and it is the goal of JGOFS to better understand the role of the oceans in global carbon cycling. Total carbon dioxide (umol/kg) and total alkalinity (umol/kg) were measured at various stations and depths from water bottle samples on the CTD rosette bottle sampler. Partial pressure of carbon dioxide (pCO2 in micro atmospheres) was measured in surface water and in air above the surface along the ship's track.
