Particulate organic carbon and nitrogen concentrations in water samples colle...

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（POC）与颗粒氮（PON）的浓度，需根据采样站位距海岸的距离以及所采样的水层深度，取用1至5升水样经沃特曼（Whatman）GF/F滤膜过滤……
