Concentrations of chlorophyll-alpha combined with different size fractions of microplankton in sea water from the euphotic zone of the Aegean Sea at Station SEPT-1997-GN36199704606MNB01

Samples from 2 l of sea water were size fractionated by filtration through polycarbonate Millipore filters with pores 0.2 µm, 1.2 µm, and 3.0 µm. The filters were kept deep frozen and analyzed according to Holm-Hansen et al. (Holm-Hansen, O., Lorenzen, C.J., Holmes, R.W., Strickland, J.D.H. 1965. Fluorometric determination of chlorophyll. Journal du Conseil Permanent International Pour L'Exploration de la Mer 30, 3-15).

采集2升海水样本，通过孔径分别为0.2 μm、1.2 μm及3.0 μm的聚碳酸酯密理博（Millipore）滤膜进行过滤以实现粒径分级。将滤膜深冻保存，并依照Holm-Hansen等人的方法开展分析（Holm-Hansen, O., Lorenzen, C.J., Holmes, R.W., Strickland, J.D.H. 1965. 叶绿素的荧光测定法. 《国际海洋勘探常设理事会期刊》, 30卷: 3-15）。
