The Seymour Arm (NTS 82M) reconnaissance-scale stream sediment and water survey was completed in 1976 and 1977. The resulting field and analytical data were released in 1978. A total of 1219 sediment and 1210 water samples were collected from 1151 sample sites.
As part of the RGS Archive Program, 1212 archived sediment pulps were re-analyzed by epi-thermal INAA and this new data along with original survey results were published in 1991. |
