Abstract

A statistical regionalization procedure was used to delineate significantly (p ⩾ 0.10) different areas, for a variety of surveillance parameters measured in 1980 in Lake Huron and Georgian Bay-North Channel. The analyses performed were compared with similar analyses done on 1971 (Lake Huron) and 1974 (Georgian Bay-North Channel) data. The regions produced from the 1980 analyses compared favourably with the 1971 and 1974 analyses. Significant (p ⩾ 0.01) increases in NO3NO2-N and RSiO2 were observed for Lake Huron between the 1971 and 1980 data sets. Significant (p ⩾ 0.01) increases in NO3NO2-N and significant (p ⩾ 0.01) decreases in TP and chlorophyll a were observed for Georgian Bay-North Channel between the 1974 and 1980 data sets.
