Nitrogen-15 Uptake, F-ratio, Ammonium Concentration, and Low-level Nitrate Concentration Measured during the U.S. JGOFS Arabian Sea Process Study
Entry ID:
USJGOFS_ARAB_NITROGEN_UPTAKE
Summary
Abstract:
A component of U.S. Joint Global Ocean Flux Study (JGOFS) is the
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 ...

Quality
Due to the strong diel patterns in nitrogen uptake and the resulting
possible misinterpretation of the N-15 uptake profile data through simple integration and daily mulitpliers, the user community is directed to the areal summary N-15 uptake data.
Access Constraints
The data are public domain and can be retrieved on-line from the
U.S. JGOFS World Wide Web server at WHOI.
Use Constraints
Anyone wishing to use U.S. JGOFS data in a presentation, report,
thesis or publication should contact the originating PI. It is expected that all customary courtesies and privileges attached to data use will be strictly honored. Ancillary Keywords
