Nutrients, dissolved oxygen, dissolved inorganic carbon and total alkalinity from water bottle samples during RV METEOR cruise M160

Discrete samples for dissolved oxygen (DO), nutrients, dissolved inorganic carbon (DIC) and total alkalinity (TA) were taken from CTD rosette casts during the RV METEOR cruise M160 in the Cape Verde region. This cruise was part of the REEBUS project focusing on researching oceanic eddies generated in the Mauritanian upwelling system. Therefore, the majority of the samples were either taken within or in close proximity to oceanic eddies. Dissolved oxygen, determined via Winkler titration, and nutrient samples, analysed with a SEAL Analytical QuAAtro AutoAnalyzer, were both measured on the vessel within 24 hours of sampling. Samples for DIC and TA analysis were taken in Duran glass bottles, poisoned with Mercury(II) chloride and stored to be analysed at GEOMAR using a SOMMA and VINDTA 3S respectively.
