Abstract: | Georgian Bay comprises the easternmost part of the Michigan-Huron water system and extensive data were collected here in 1974 by the Canada Centre For Inland Waters. Fifty-one stations were monitored between April and December of 1974; the time series recordings of currents and temperature at 10 locations, meteorological recordings at two buoys, and water level recordings from temporary gauges were carried out. Minimum surface temperature of 0 °C persists for one month commencing in late February and maximum surface temperatures occurred in early August (19 °C). The annual heat income for Georgian Bay was estimated to be 43 700 cal · cm–2. The exchange at Main Channel has a significant influence on water residence and flushing times in Georgian Bay which determines its trophic status. |
