The Alert Bay/Cape Scott (NTS 92L/102I) reconnaissance-scale stream sediment and water survey was completed in 1988 and the resulting field and analytical data were released in 1989. A total of 1207 sediment and 1174 water samples were collected from 1140 sample sites. Moss-mat sediment and stream water samples were collected from 984 sites on Vancouver Island. Stream sediment and water samples were collected from 156 sites on the mainland. |
