For determining POC and PON concentrations 1 to 5 litres (depending on the distance of the station from the coast and the depth layer sampled) were filtered through Whatman GF/F...为测定颗粒有机碳（Particulate Organic Carbon，POC）与颗粒有机氮（Particulate Organic Nitrogen，PON）的浓度，需根据采样站距海岸的距离以及所采集水层的深度，取1至5升水样通过沃特曼（Whatman）GF/F滤膜进行过滤……
