Survey Description


During the summer of 1982, a helicopter supported lake sediment sampling survey was conducted by J. Descarreaux and Associates (NTS 23M/4, 5, 6, 23L/12, 13, 24D/4, 5, 12, 13 and 24P/1, 2,3, 6-11, 14-16, 24A/1, 2,3, 6-11, 14-16, 23I/9-11, 14-16).  The area covers 26000 km2.  A total of 1901 samples were collected from lakes with surface area of km2. At an average density of 1 sample per 12.0 km2, it was sometimes necessary to sample bigger lakes with many sites of sampling.  Lakes were sampling along their central axis, generally in the center of that axis.

Samples were analysed for:

 

Element Dissolution Technique
Ag, Al, B, Ba, Be, Ca, Cd, Ce, Co, Cr, Cu, Eu, Fe, K, La, Li, Mg, Mn, Mo, Na, Ni, P, Pb, Sc, Sm, Sr, Th, Ti, V, Y, Zn

HNO3

ICP-ES
U   fluorimetry
Hg   flameless atomic absorption
pH, Loss on ignition (LOI)    
As    

 

The data are published in Open File DP 82-16, Department of Energy and Resources, 1982.  Subsequently, samples were analysed for arsenic and the data are published in Open File DP 83-18, Department of Energy and Resources, 1983.
