Interstitial waters of marine sediments were separated into the two portions. A large interstitial water was extracted from sediment core samples by a centrifugation at 42×g for 30min, and then a small interstitial water was extracted at 1, 500×g from the residual sediment samples. The content of the large interstitial water was high in sandy sediment, while the small interstitial water was in silty and clayey sediment. Concentrations of polymeric carbohydrates were higher in the small interstitial water than in the large interstitial water, although no difference was found in monomeric carbohydrate. It was suggested that monomeric carbohydrates were uniformly distributed in marine sediments by diffusion, while polymeric carbohydrates were not.
