Abstract
The objectives of this study are two-fold: (1) to describe and quantify the seasonal physical and chemical limnological properties of Pavilion Lake, a microbialite-rich lake in British Columbia, Canada, and (2) to gain a broader limnological context of Pavilion Lake by examining the limnology and hydrology of the lakes and groundwater systems in the area (~30 km radius). Pavilion Lake is a dimictic lake with annual ice-cover. lt is a hard water (mean CaCO sub(3) = 181.8 mg L super(-1)), ultra-oligotrophic (mean Total Phosphorus [TP] = 3.3 mu g L super(-1)) lake, that is groundwater fed most likely through diffuse, low velocity local and regional sources. Principal Components Analysis (PCA) separated Pavilion Lake from the other groundwater, stream and lake samples along a conductivity and pH gradient an Axis 1 ( lambda sub(1), =0.392), and a nutrient (Total Nitrogen [TN], TP) and K super(+), Mg super(+2), Si gradient on the second axis ( lambda sub(2) = 0.160). Pavilion Lake has the lowest Ca super(+2) and TP concentrations, and the highest Na super(+) concentrations and optical transmissivity amongst all sampled sites. Furthermore, the lake is characterized by low sedimentation rates. These characteristics are potentially important factors in supporting the past and on-going development of microbialites within the lake. Our study provides a limnochemical reference to consider in the conceptualization of ideal environments supporting large-scale microbialites.
