Title: Rice and Sturgeon Lakes Nutrient Budget Study: Release of phosphorus from Rice Lake sediments
Author: Andrews, D.
Abstract: Comparisons were made in the laboratory, under anoxic and aerobic conditions, of the phosphorus release rates from sediments collected from the deepest areas of Rice Lake. As well, cores containing sediment and lake water collected from two shallow locations were incubated in situ to determine if there were diurnal differences in the phosphorus release rates. The estimate of the average deep water phosphorus release rate of 0.53 mg P/m2/day was based on highly variable results among replicates and between sites and included estimates of release under both oxic and anoxic conditions. There was no evidence of any diurnal pattern of release over a 24-hour period of observation of the shallow water sediments in October.
