Survey Description


Between June 18 and August 1, 1980, 2593 lake sediment samples were collected from 2450 sites in northeastern Newfoundland.  Sites were sampled at an average density of one site per 7 km2 over the 17,000 km2 survey area.  The data are published in four open files, one for each NTS sheet as well as a compilation open file which combines all four OFs:

Map Sheet Open File Year
2C 2C/49 1981
2D 2D/114 1981
2E 2E/409 1981
2F 2F/16 1981
2C, D, E, F NFLD/1256 1981

 

Samples from these areas were reanalyzed by INAA and published with samples from the same map sheets collected in other years in the following Open Files:

Map Sheet Open File Year
2D 2D/175 1988
2E 2E/563 1988
2C, F NFLD/2273 1993

 

Sampling Procedure

A lead-weighted, hollow, pipe-like sampler was dropped from the float of a Bell 206B helicopter through the water into the lake bottom.  It was retrieved with a rope attached to a metal loop.  The sampler was then inverted to slide the sediment out into a scoop.
