Concentrations of chlorophyll-alpha in water of the Ionian Sea at Station MARCH-2000-IRI30

Samples from 2 l of sea water were filtered through polycarbonate Millipore filters. 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，通过密理博（Millipore）聚碳酸酯滤膜进行过滤处理。将所得滤膜置于深冻环境保存，并依据Holm-Hansen等人的分析方法（Holm-Hansen, O., Lorenzen, C.J., Holmes, R.W., Strickland, J.D.H. 1965. 叶绿素荧光测定法. 《国际常设海洋勘探理事会期刊》, 30卷, 3-15页）完成分析。
