Survey Description
In August 1986, 4Lwater samples and lake sediment cores were collected from 149 lakes and ponds in the Mitchell Lake area, 70 km north of Sault Ste. Marie, northern Ontario.
The survey, which is the culmination of work carried out since 1980, studies the relationships between geochemistry/limnology and remote sensing.
In order to distinguish between recent anthropogenic inputs ot lake sediments and historical concentrations, the lake sediment cores were separated into two subsamples: the "pre-Ambrosia" sample (depths >18 cm), representing sediment which was laid down in excess of ~100 years ago, and the "post-Ambrosia" sample, (the top 10 cm of the core).
The data and a detailed description of the study are published on Ontario Geological Survey Map M80798.
Some of the data from this survey are compiled in the Trout Lake regional geochemical map sheet, OGS Map M80803. The data used in this compilation are published in OGS Miscellaneous Release Data, MRD005.
