This data set was collected in support of an investigation of the variability of particulate organic matter content and composition across a high-resoultion latitudinal transect across the Atlantic Ocean during the PS113 expedition. 4L of seawater from the clean ships' underway system were filtered on a 0.7 µm pre-combusted GFF filter. Samples were snap-frozen and stored at -80°C while at sea. Samples were acid fumed and dried before analyses. Particulate organic carbon and particulate nitrogen contents were measured using an Euro EA elemental analyzer (CHNS; EuroVector, Italy). This data reflects high-resolution spatial variabilites in particulate organic carbon and particulate nitrogen concentrations in surface waters accompanied by few samples from higher depths (0 - 400 m).
