2005-2009 River and Soil Dissolved organic carbon (DOC) and total dissolved nitrogen (TDN) concentrations, Cape Bounty

Samples were vacuum filtered using a glass filtration apparatus and precombusted 0.7 um GF/F glass fibre filters. In 2007 and 2008, samples were pressure filtered using a stainless steel apparatus. Filtration apparatus was soaked overnight in 30% hydrogen peroxide or 3% HCl, and triple rinsed with deionised water and sample for each use. Samples were stored cool in the dark (refrigerated) in amber glass EPA vials, and acidified to a pH of 2 upon return to the laboratory. DOC concentrations were measured as non-purgeable organic carbon via high temperature combustion (720°C) with a Shimadzu TOC-VCPH analyser using a high sensitivity platinum catalyst in line with a total nitrogen module (TNM-1 unit). TDN concentrations were measured as nitrogen monoxide via thermal decomposition. Samples named by site abreviation, date (MMDD) and time: PT0714 1300 = Ptarmigan July 14th at 1 pm.
