Primary Production 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. Chlorophyll-a was measured by fluorometric method. Primary production and carbon assimilation per unit chlorophyll-a are given for 12 hour (dawn to dusk) and 24 hour (dawn to dawn) periods at several depths in the euphotic zone.

In addition, euphotic zone depth (depth at which light is 1 percent of surface incident radiation) and diffuse attenuation coefficient are given for various stations. The data is public domain and can be retrieved on-line at "usjgofs.whoi.edu/jg/dir/jgofs/" [This information was obtained from U.S. JGOFS website at WHOI.]
