Particulate organic carbon and nitrogen concentrations in water samples collected at Station SEPT-1997-GN36199704606MNB04 in the Aegean Sea

Seawater samples (1-5 l depending on distance of a station from a coast and depth of sampling) were filtered through Whatman GF/F filters (diameter 2.5 cm). Then the filters were wrapped in aluminium foil and stored at 22°C until analysis according to Hedges and Stern (Hedges, J.I., Stern, J.H. 1984. Carbon and nitrogen determinations of carbonate-containing solids. Limnol. Oceanogr., 29(3), 657-663; http://www.aslo.org/lo/toc/vol_29/issue_3/0657.pdf)
