Total dissolved carbohydrates (DCHOs) were determined in interstitial waters collected at open-ocean and Peru margin sites cored during Ocean Drilling Program Leg 201. Concentrations of DCHOs ranged from 0 to approximately 1500 mu M and showed no consistent trends between openocean and Peru margin sites either in the magnitude or direction of downhole interstitial water gradients. In contrast, relative DCHO concentrations (normalized to dissolved organic carbon concentrations) were higher in open-ocean vs. margin sediments. These trends are consistent with results from more shallow estuarine and nearshore continental margin sediments and may be related to changes in the overall controls on sediment organic matter remineralization with decreasing remineralization rates.
