Interannual variability in trophic status of shallow lakes on the Boreal Plain is there a climate signal?

We explored relations between climate and trophic status of shallow lakes (lake area >5 ha, mean depth <3.2 m) located on the subhumid western Boreal Plain of Canada. Correlation and regression analyses were used to assess the association between indicators of climate and satellite-based estimates of trophic status (chlorophyll a (Chl a)).
