Physical, chemical, and biological CTD and bottle data from NATHANIEL B. PALMER in eastern tropical South Pacific Ocean near Peru/Chile from 2013-06-24 to 2013-07-22 (NCEI Accession 0128141)
This report contains data from R/V Nathaniel B. Palmer cruise NBP 1305 to the eastern tropical south pacific oxygen deficient zone. The objective of the cruise was to study denitrification and anammox processes. The cruise took place between June and July in 2013 in an area bounded by 23S-10S and 87W-70W. 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.

Purpose | Marine waters in a relatively large area off the coast of Peru/Chile contain little to no dissolved oxygen. This is a natural phenomenon that only occurs on such large scales in two other oceanic areas: the west coast of Mexico and in the central Arabian Sea. Because of the very low oxygen anaerobic metabolisms that use oxidized nitrogen compounds become the dominant energy production pathways between about 200 and 800 meters water depth. Up until a few years ago it was thought that the denitrification metabolism was the dominant heterotrophic metabolic pathway but it is now argued that the anammox pathway may be dominant. Consequently, we propose to study these two pathways, along with other possible ones, in the very low oxygen waters off Peru/Chile during a cruise of the research vessel R/V Palmer between 24 June and 22 July 2013. Water samples were collected for chemical and molecular analysis and rates of denitrification and anammox were determined by incubation experiments using stable isotopes of nitrogen as tracers. |
