Abstract

Abstract

During the cruise of CHINARE-18, the concentration and profile characteristics of nutrients in the sediment interstitial water from the Southern Ocean were determined.The results show that the concentration of SiO₃-Si and NH₄-N are much higher than other nutrients.The profile of SiO₃-Si was characterized by sharp gradients near the sediment-water interface, profile distribution of silicate show that during the diagenetic reaction of silicate, dissolution is the main part.The organic matter decomposition was occurred under the anaerobic condition.Benthic fluxes of SiO₃ Si, NH₄-N were from interstitial water to overlying water, and regeneration of silicate and ammonium was the main part of the nutrient regeneration in sediment interstitial water of the study area.
