Effects of ice cover on dissolved oxygen in Silver Lake, Ontario / R.J. Maguire and N. Watkin.: En36-503/89E-PDF
"Weekly sampling was performed at the deepest point (23 m) of Silver Lake for a few chemical parameters during the late fall and winter of 1973-74. The amount of dissolved oxygen in most of the water column decreased by about 2 ppm during the winter. At the bottom, the decrease in dissolved oxygen amounted to 4-5 ppm, and the level of hydrogen sulfide increased significantly. This decrease in the amount of dissolved oxygen is probably due to the prevention of atmospheric mixing by the ice and snow cover. In general, the amounts of orthophosphate, nitrate, chloride and total organic carbon remained constant during the winter, as did the values of specific conductance and pH"--Abstract, p. v.
