Monosaccharide composition of acid‐hydrolyzable carbohydrates was analyzed in particulate matter collected during a plankton bloom in the northern North Sea. Concentrations of total particulate carbohydrates varied from 50 nmol·liter −1 to >600, with maximum concentrations in the upper layers above 1% light depth. The monosaccharide spectra, considered in conjunction with those of dissolved carbohydrates from the same samples, suggest that the variations observed were caused by variations in the production of carbohydrates by phytoplankton and significant loss of produced carbohydrates into the dissolved fraction. Two loss phases could be discerned: first, labile glucose polymers, followed by the relatively stable structural polysaccharides.
