Abstract

This dataset consists of 795 measurements of micromolar nutrient concentrations made on samples collected during the Atlantic Meridional Transect programme cruise 23 (AMT23 JR20131005) between 1st October and 11th November 2013. The cruise track between UK and Chile passed through both north and south Atlantic gyres. This dataset contributes to the AMT time-series of core oceanographic measurements along a north-south transect of the Atlantic Ocean. Samples were collected on a daily basis at 10 to 17 depths in the upper 500m using a CTD rosette with 24 x 20 L OTE (Ocean Test Equipment) bottles. Samples were analysed within 3-4 hours of collection for 'nitrate+nitrite', nitrite, phosphate and silicate using a 5-channel Bran and Luebbe AAIII segmented flow, colourimetric, auto-analyser (Brewer and Riley (1965) for nitrate, Grasshoff (1976) for nitrite, Kirkwood (1989) and Mantoura and Woodward (1983) for phosphate and silicate). Established, proven analytical protocols were used.
