Effect of Temperature and Dissolved Oxygen on Sediment-Water Nutrient Flux

摘要

A series of experiments was conducted to determine the influence of water-column temperature and dissolved oxygen on sediment-water nutrient flux. Three nutrients were considered: ammonium nitrogen, nitrate nitrogen, and ortho phosphorus. Results of the experiments indicated that nutrient concentration in the overlying water had to be considered, as well as temperature and dissolved oxygen, as an independent variable which affected sediment-water nutrient flux. Experiments were conducted on intact sediment cores removed from Gunston Cove, Virginia, during the interval July to October, 1984.
