In two very different areas in the North Sea, Aberdeen Bay (7 m) and the Fladen Ground (140 m) seasonal cycles of C 14 uptake, chlorophyll and particulate organic carbon were observed. The ratios of C 14 uptake to chlorophyll concentration showed marked variations seasonally. There were no signs of “dead” chlorophyll or of a decrease in the ratio due to nutrient deficiency. The ratios of chlorophyll to particulate carbon suggest that in coastal waters living plants generally form the most important part of the particulate carbon. At the deeper position the ratio was much smaller so that chlorophyll is not a good index of organic matter in the water.
