NGR lake sediment and water survey; NTS 74E, 74L, 74M, northeastern Alberta, 1993
(requires an Internet connection)
Helicopter-supported sample collection was carried out in northeastern Alberta during the summer of 1993. Lake sediment and water samples were collected at 1160 sites at an average density of one sample per 19 km2 throughout the 22,100 square kilometres covered by the survey. Sample site duplicate samples were collected in each analytical block of twenty samples. The data are published in GSC Open File 2856.
This survey was carried out using National Geochemical Reconnaissance (NGR) protocols.
