Description
Summary:<p>Water was pumped to the surface using a trace metal clean diaphragm pump and acid cleaned teflon tubing and dispensed into trace metal clean (TMC) 50 L carboys. Sampling occurred between 18:00 and 19:00 in open air, with wind coming strictly from over open water, NNE to NE.&nbsp; The carboys were protected from light with dark plastic bags and returned to the Crary Laboratory at McMurdo Station via helicopter within one hour of sampling.</p> <p>Chl <em>a</em> was measured using 90% acetone extracts and the non-acidified fluorometric method, employing a Turner Designs fluorometer and Whatman GF/F filters.</p> <p>Nitrate (NO<sub>3</sub><sup>-</sup>), nitrite (NO<sub>2</sub><sup>-</sup>), phosphate (PO<sub>4</sub><sup>3-</sup>) and silicate (SiO<sub>4</sub>) concentrations were measured in duplicate on a Lachat QuikChem 8500 autoanalyzer.&nbsp; Ammonium (NH<sub>4</sub><sup>+</sup>) concentrations were measured in triplicate using the phenol-hypochlorite method.</p>
