NODC Accession 0112418 includes profile, discrete sample and chemical data collected aboard the NATHANIEL B. PALMER during cruises NBP0103, NBP0104, NBP0202 and NBP0204 in the South Atlantic Ocean and South Pacific Ocean from 2001-04-29 to 2002-09-12. These data include NITRATE + NITRITE CONTENT (CONCENTRATION), PHOSPHATE, NITRITE, SILICATE, AMMONIUM and NITRATE. The instruments used to collect these data include bottle and CTD. These data were collected by Kent Fanning of University of South Florida as part of Southern Ocean GLOBEC. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NODC on 2013-07-25.

Nutrients from Bottle Casts

Methods
Analytical methods used for silica, phosphate, nitrite, and nitrate follow the recommendations of Gordon et al. (1993) for the WOCE WHP project.
The analytical system we employ is a five-channel Technicon Autoanalyzer II upgraded with new heating baths, proportional pumps, colorimeters, improved optics, and an analog to digital conversion system (New Analyzer Program v. 2.40 by Labtronics, Inc.) This Technicon is designed for shipboard as well as laboratory use.
Silica is determined by forming the heteropoly acid of dissolved orthosilicic acid and ammonium molybdate, reducing it with stannous chloride, and then measuring its optical transmittance.
Phosphate is determined by creating the phosphomolybdate heteropoly acid in much the same way as with the silica method. However, its reducing agent is dihydrazine sulfate, after which its transmittance is also measured. A heating bath is required to maximize the color yield.
Nitrite is determined essentially by the Bendschneider and Robinson (1952) technique in which nitrite is reacted with sulfanilamide (SAN) to form a diazotized derivative that is then reacted with a substituted ethylenediamine compound (NED) to form a rose pink azo dye which is measured colorimetrically.
Nitrate is determined by difference after a separate aliquot of a sample is passed through a Cd reduction column to convert its nitrate to nitrite, followed by the measurement of the "augmented" nitrite concentration using the same method as in the nitrite analysis.
In the analytical ammonia method, ammonium reacts with alkaline phenol and hypochlorite to form indophenolblue. Sodium nitroferricyanide intensifies the blue color formed, which is then measured in a colorimeter of our nutrient-analyzer. Precipitation of calcium and magnesium hydroxides is eliminated by the addition of sodium citrate complexing reagent. A heating bath is required. Our version of this technique is based on modifications of published methods such as the article by F. Koroleff in Grasshoff (1976). These modifications were made at Alpkem (now Astoria-Pacific International, Inc.) and at L.Gordon's nutrient laboratory at Oregon State University.
Data
Nitrate, nitrite, phosphate, ammonia, and silica were measured from every niskin bottle tripped from all hydrocasts on this cruise. All concentrations are reported in micromoles per liter.
