Newfoundland and Labrador
Lake sediment sampling, NTS 13E/6, 7, 13M/8, 9, 13N, 5, 12, central Labrador, 1998.

In 1998, lake sediment samples were collected from the Wilson Lake area and the Pants Lake Intrusive area, central Labrador in a high density lake sediment survey. The centre of the lake or central basinal portion of the lake was sampled. On some deep lakes (>25 m) no sample could be collected in lake centres and a sample from a shallower site closer to shore was obtained. The data are published in Newfoundland and Labrador Department of Mines and Energy Open File LAB/1362.
Report and data on CD.
<0.180 mm fraction of lake sediment by ICP-ES after HF-HClO4-HCl digestion and by INAA for large suites of elements; by AAS after HNO3 digestion for Ag; by fluoride-ion specific electrode with digital ion analyzed after Na2CO3:KNO3 flux and fusion for F; by FA-ICP-MS after HNO3-HCl digestion for Pd, Pt.
Geochem Maps Available:
Proportional symbol maps showing distribution of selected elements in lake sediment. Histograms of selected elements in lake sediment.
A weighted tubular sampler fitted with a nylon rope for retrieval was dropped from a float equipped helicopter. Samples were stored in water resistant Kraft paper bags.

The geographic extent of the survey is defined by the following polygons:
Covers parts of NTS 13E/6 (Metchin River) and 13E/ 7 (Wilson Lake), central Labrador. The Trans Labrador Highway (Hwy 500) runs though the southwest part of the study area and the western half of Wilson Lake is located in the southeast part of the study area.
Covers parts of NTS 13M/8, 9 (both untitled) and 13N/5, 12 (both untitled), the Pants Lake intrusion area, central Labrador. It is located just west of Sarah Lake.
