Particulate organic carbon and nitrogen concentrations in water samples collected at Station SEPT-1997-GN36199704606MNB03 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)

海水样品体积为1-5升，具体取值依据采样站位距海岸的距离及采样水深而定，经Whatman GF/F滤膜（直径2.5厘米）过滤。随后将滤膜用铝箔包裹，保存于22℃，直至按照Hedges与Stern的方法开展分析（Hedges, J.I., Stern, J.H. 1984. 含碳酸盐固体的碳与氮含量测定. 湖沼学与海洋学, 29(3), 657-663; http://www.aslo.org/lo/toc/vol_29/issue_3/0657.pdf）
