| Summary: | This
survey report presents basin morphology, water quality, and sedimentological data from
twenty-one Mongolian lakes, and is meant to be used as a resource for future geological and biological
investigations. The lakes are organized in three separate groups based on geographic location, and the
survey results from each lake are described in detail. A short discussion of local and regional factors
infl uencing solute concentrations and pH levels of the lakes’ waters is presented. The lakes present
at latitudes lower than N 50°00’ (i.e. central and north/central lakes) are distributed across an area of
approximately 150,000 km
2
and vary considerably with respect to their water quality characteristics.
Regional precipitation patterns as a function of geographic location and/or catchment specifi c
processes are indentifi ed as the driving mechanisms for variations in solute concentrations and pH
levels in these lakes. The surveyed lakes present at latitudes higher than N50°00’ (i.e. northern lakes)
are distributed across a smaller area (approximately 180 km
2
) and have relatively little variation in
water quality characteristics. These lakes straddle the local taiga/alpine tundra transition zone, and
elevation (i.e. valley placement) is identifi ed as the driving mechanism for inter-lake variations in
solute concentrations and pH levels. |
