Open File 3617



Open File:  3617
Previous OF publication(s):  
Province / Territory:  New Brunswick
Funding Source:  Federal and Provincial (1985); Provincial (1997)
Year of Collection:  1997

Survey Type:  Regional Stream Survey
# Lake sites:  0
# Stream sites:  1074
Survey Area:  3880 km²
NTS Sheet(s):  021O/11, parts of 021O/10, /14, /15, /16

The regional stream survey for northwest New Brunswick (NTS 21O/11 and parts of 21O/10, 21O/14, 21O/15 and 21O/16) was conducted during the summers of 1985 and 1997.

This report presents analytical and statistical data for 14 elements plus loss-on-ignition in stream sediments from 729 sample sites, collected at an average density of one sample per 3.6 km². Uranium, fluoride, and pH values in waters from these sites are included in this report. In addition, 345 samples representing a subset from an adjoining NGR survey (Open File 1211, 1986) were reanalyzed and appear in the data listing. The original values for uranium, fluoride, and pH in waters from Open File 1211 survey are included in this report.

Other information:

A subset of sediment samples (345 sites) from Open File 1211 was reanalyzed by wet chemical methods and the data published in Open File 3617. Subsequently, all samples were reanalyzed by INAA and data published in NBDNRE Open File Report 98-15 (revised).

Data released on 3.5" diskette only.
