Physical, chemical and biological CTD and bottle data from R/V Thomas G. Thompson cruise TN278 in eastern tropical North Pacific Ocean from 2012-03-19 to 2012-04-20 (NCEI Accession 0109846)

This report contains data from R/V Thomas G. Thompson cruise TN278 to the eastern tropical north pacific oxygen deficient zone. The objective of the cruise was to study denitrification and anammox processes. The cruise took place between March and April in 2012 in an area bounded by 26N-14N and 102W-114.5W. Two data sets are included. The first is the 1-meter binned CTD data while the second is the bottle cast data and contains nutrient values for nitrate, nitrite, silicate, phosphate and ammonium. The data were collected as part of NSF grant number OCE-1029316 to Allan Devol. CTD data has been reprocessed and aligned and outliers have been removed. Nutrient samples were filtered (GFF glass fiber) before analysis and analyzed using the US-JGOFS protocols (http://usjgofs.whoi.edu/protocols_rpt_19.html). All data are considered final.
