Nutrient concentrations in water samples collected at Station APRIL-2000-K3 in the Northeastern Aegean Sea

For nutrient determination samples were collected in 100 ml polyethylene bottles and kept continuously under deep freeze (-20°C) until their analysis in the laboratory. PO4 concentrations were measured on a Perkin Elmer Lambda 2S UV/VIS Spectrometer according the protocol of Murphy and Riley (1962). […]为开展营养盐测定，样本采集于100 ml聚乙烯瓶中，并持续置于-20℃深低温环境下保存，直至送至实验室开展分析。 磷酸盐（PO4）浓度的测定采用珀金埃尔默（Perkin Elmer）Lambda 2S紫外可见分光光度计（UV/VIS Spectrometer），依照Murphy与Riley（1962）的实验规程进行。[…]
