(requires an Internet connection)
Helicopter and truck-supported sample collection was carried out in the Dease Lake map area, British Columbia during the period July 29 to August 16, 2000. A total of 963 stream sediment and 946 stream water samples were collected from 908 sites. The average sample site density was 1 site per 13.2 km2 over the 12,000 square kilometre survey area. Field duplicate samples were collected in each analytical block of twenty samples. The data are published in British Columbia Regional Geochemical Survey RGS 55/GSC Open File 4011.
This survey was carried out using National Geochemical Reconnaissance (NGR) protocols.
Sediment samples weighing 1 to 2 kg were obtained from the active stream channel. Samples were primarily fine-grained material mixed with varying amounts of coarse sand, gravel and organic material. Surface water samples were collected in 250 mL bottles and at every fifth site, an additional 60 mL water sample was collected. Suspended solids were excluded where possible.
