Organic Carbon and Nitrogen Measured during the U.S. JGOFS Arabian Sea Process Study
Listed in NASA Earthdata CMR
A component of U.S. Joint Global Ocean Flux Study (JGOFS) is the Arabian Sea Process Study.
Description
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. Particulate organic carbon (POC) and particulate organic nitrogen (PON) were measured in profile on CTD casts for cruises TTN-043, TTN-045, TTN-049, TTN-053, and TTN-054. POC and PON values are available in micromoles per liter and as carbon-to-nitrogen molar ratio for each depth.

POC and PON were determined by filtration and combustion of water samples from the CTD rosette bottle sampler. (Investigators: Azam, Smith, Ducklow, Balch) Total organic nitrogen (TON) was measured in profile on CTD casts for cruises TTN-043, TTN-045, TTN-049, TTN-050, TTN-053, and TTN-054. TON is available in micromoles per liter for each depth.
(Investigator: Hansell) Total organic carbon (TOC) was measured in profile on CTD casts for cruises TTN-043, TTN-045, TTN-049, TTN-050, TTN-053, and TTN-054. TOC is available in micromoles of carbon per liter and micromoles of carbon per kilogram for each depth.
