NTS 104O - Jennings River


BC RGS 52 /
GSC OF 561 / NGR 41 / GSC OF 733 / GBC 2011-2

 

 

The Jennings River (NTS 104O) reconnaissance-scale stream sediment and water survey was completed in 1978 and the resulting field and analytical data were released in 1979. A total of 946 sediment and 944 water samples were collected from 892 sample sites. The survey also included the collection of lake sediment and water samples from 75 sites.

 

As part of the RGS Archive Program, 893 archived sediment pulps were re-analyzed by epi-thermal INAA and this new data along with original survey results were re-published in 2000.

 

Geoscience BC Report 2011-2 reports on the Northern BC Reanalysis Project -a continuation of a series of large-scale reanalysis initiatives that have been sponsored by Geoscience BC since 2007.  Recognized as a cost-effective means of updating information collected during older government funded regional geochemical surveys, these programs have significantly improved the BC geochemical database by providing a wide range of new analytical information at improved detection levels plus greater data compatibility with analytical methods currently being employed.  Digital data file includes new ICP-MS analytical results for a total of 7,651 stream and lake sediment samples.
