A total of 1938 sets of time series data (in situ chlorophyll a, temperature and depth) at two-hour intervals were obtained. Chlorophyll a was low (less than 1 μg/l) under cold temperature below -1.5℃ until middle March. From middle March to middle April, when the fast ice still covered the lagoon surface, chlorophyll a increased greatly to 4-5 μg/l. Thereafter it decreased to 2 μg/l.}, pages = {9--15}, title = {A phytoplankton bloom under sea ice recorded with a moored system in lagoon Saroma Ko, Hokkaido, Japan}, volume = {2}, year = {1989} }
