Open File 1209

Open File:  1209
Previous OF publication(s):  0559
Province / Territory:  Newfoundland & Labrador
Funding Source:  
Year of Collection:  1978

Survey Type:  Regional Lake Survey
# Lake sites:  0
# Stream sites:  0
Survey Area:  18000 km²
NTS Sheet(s):  014D, 014C, 024A

The regional lake survey for northern Labrador (NTS 14D and parts of 14C and 24A) was conducted during the summers of 1978 and 1985.

The data for NTS 14D, with the exception of mercury, was originally released as Open File 559 (published 1979). This report presents analytical and statistical data for 17 elements in lake sediments from X sample sites, collected at an average density of one sample per 13 km². Loss-on-ignition in sediments, and uranium, fluoride, and pH values in waters from these sites are included in this report.
