Chlorophyll a measured on water bottle samples during AEGAEO cruise LIA-7@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升海水样本，经聚碳酸酯密理博（Millipore）滤膜过滤。将所得滤膜低温冷冻保存，并参照Holm-Hansen等人（Holm-Hansen, O., Lorenzen, C.J., Holmes, R.W., Strickland, J.D.H. 1965. 荧光法测定叶绿素. 《国际海洋考察理事会期刊》, 第30卷, 第3-15页）的方法完成分析。
