Abstract:
Nutrient data from Nisken Bottle samples collected and measured onboard Sonne Expedition SO-245 "UltraPac". Concentrations of dissolved inorganic phosphate (PO43-), nitrite (NO2-), nitrate (NO3-), and silicate (Si) were measured with the QuAAtro39 autoanalyser (Seal Analytical) using the method based on Strickland and Parsons, 1972. OSIL Seawater Low-Nutrient Standards were used as a secondary standard to test primary standard calibrations. Low concentrations of dissolved phosphate (<300 nM) were determined with a long waveguide capillary cell (LWCC) set-up, which included a Traacs 800 pump and autosampler, a World-Precision 100 cm LWCC, an HL 2000 Lamp from Ocean Optics and a STS-VIS Miniatur Spectrophotometer from Ocean Optics. Minimum quantifiable limits were set at 2 times the Minimum Detection Limit given for the method. Oxygen was measured on selected samples by Winkler titration for the purpose of calibrating the CTD O2 sensor. Temperature, Salinity, Sigma-Theta, and Dissolved Oxygen data are included for information and derive originally from: Zielinski, Oliver; Henkel, Rohan; Voß, Daniela; Ferdelman, Timothy G (2018): Physical oceanography during SONNE cruise SO245 (UltraPac).PANGAEA, https://doi.org/10.1594/PANGAEA.890394
