Description:
This data was collected to investigate spatial differences in dissolved inorganic nutrient concentrations in surface waters of the Atlantic Ocean as part of the PS113 expedition. Water samples for dissolved inorganic nutrient concentrations including Nitrate, Silicate and Phosphate were filtered through a 0.2 µm syringe filter and stored at -80°C while at sea. Nutrient concentrations were assayed on an Evolution 3 Alliance Autoanalyser and calibrations were corrected for concentrations using certified reference material (CRM) 7602a (JAMSTEC; JAPAN) and MERCK STD (NIST-Standard). Concentrations were calculated by means of standard colorimetric techniques (Grasshoff, Kremling, & Ehrhardt, 2009).
