Concentrations of chlorophyll-alpha in sea water from the euphotic zone at Station SEPT-94-GN3619940280301210 in the Aegean Sea

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升海水样本，经聚碳酸酯密理博（Millipore）滤膜过滤。将滤膜置于深冻环境保存，并依据Holm-Hansen等人1965年提出的方法开展分析：Holm-Hansen, O., Lorenzen, C.J., Holmes, R.W., Strickland, J.D.H. 荧光法测定叶绿素. 《国际常设海洋勘探理事会期刊》, 30卷, 3-15页。
