Bacterial Abundance and 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. The CTD rosette bottle sampler was used to collect water samples at various depths. Water samples were filtered and stained.

Bacteria were counted by epifluorescence microscopy. The water samples were also incubated with 3H-leucine and 3H-thymidine to determine leucine and thymidine incorporation. These values can be used to calculate bacterial production.
The final dataset contains depth profiles of bacterial abundance, leucine incorporation, and thymidine incorporation for four of the eleven cruises. 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.]
