Concentrations of chlorophyll-alpha in sea water from the euphotic zone at Station MARCH-1998-GN36199804611MNB04 in the Aegean Sea@en

Samples from 2 l of sea water were filtered through polycarbonate Millipore. 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).取2升海水样品，采用密理博（Millipore）聚碳酸酯滤膜进行过滤。将所得滤膜进行深冻保存，并依据Holm-Hansen等人（Holm-Hansen, O., Lorenzen, C.J., Holmes, R.W., Strickland, J.D.H. 1965. 叶绿素的荧光光度测定法. 《国际海洋勘探常设理事会期刊》（Journal du Conseil Permanent International Pour l'Exploration de la Mer），第30卷，第3-15页）的方法进行分析。
