Short summary
We report results from an intercomparison exercise on the analysis of nutrients at sea. Two independent teams (Marine Institute, Ireland and Dalhousie University Canada) carried out an analysis of a GO-SHIP hydrographic section. The cruise provided a unique opportunity to assess the likely comparability of nutrient data collected following GO-SHIP protocols. Datasets were high quality and compared well but highlighted a number of issues relevant to the comparability of global nutrient data.
