NGR lake sediment and water survey, parts of NTS 064B and 064C, Manitoba, 1987.
(requires an Internet connection)
This survey is one of 3 surveys completed in the Leaf Rapids – Lynn Lake area between 1985 and 1988 that together represent the first infill lake surveys to be carried out in Manitoba. They were designed to augment existing geochemical data in areas of high mineral potential.
In 1987, approximately 350 lake sediment and water samples were collected by GSC personnel during a helicopter-supported program. The data are published in GSC Open File 1959.
This survey was carried out using National Geochemical Reconnaissance (NGR) protocols.
Lake sediments were collected using a modified model of the GSC 1976 lake sediment sampler from the profundal basin of a lake 1-5 km2 in area and 3-5 m deep. The top several centimetres of the sediment column was discarded, retaining thixotropic gel-like material which was placed in high wet-strength paper bags for drying and transport. Lake waters were routinely collected at sediment sites in 250 mL Nalgene bottles from at least 30 cm below the water surface.
