Temperature, Salinity and Nutrients from Niskin Bottles 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. Niskin bottles were used on a CTD rosette bottle sampler to collect water samples at various depths. The water samples were measured for salinity, oxygen (Winkler and colorimetric techniques), nitrate, nitrite, ammonium, phosphate, and silicate.
