Regional Stream Sediment and Water Survey over the Northern Mainland Nova Scotia and Cape Breton Island
DP ME 136, Version 2, 2006. Regional Stream Sediment and Water Surveys by the Nova Scotia Department of Natural Resources over the Northern Mainland Nova Scotia and Cape Breton Island, 1982-1983
Abstract
A regional stream sediment and water survey was conducted in northern mainland Nova Scotia and Cape Breton Island in 1982-1983 by the Nova Scotia Department of Mines and Energy for a project funded by the Canada - Nova Scotia Cooperative Mineral Program. Approximately 4100 samples were collected, including standards and duplicates, at a linear spacing of one sample/2 km. Stream samples were analyzed for: Zn, Cu, Pb, Ni, Co, Ag, Mn, As, Mo, Fe, Hg, and U, while stream water samples were analyzed for F and U. There was no stream sediment field survey in 1981. Stream sediment and water samples prefixed by 1981 are a re-analysis of the Department's 1970's stream sediment sampling program (Antigonish, Cape Breton and Cobequid Highlands).
Samples were re-analysed at a new linear spacing of one sample/2 km, instead of the original one sample/300 m linear spacing. The results of the 1982-1983 survey were merged with the re-analysis of the 1981 survey to yield the 1981-83 survey. This data set was previously included as part of a compilation of geochemical surveys and released as DP ME 004 Version 1. This data set previously consisted of str813b1 and stw83b1, which were later renamed to c136nccd and c136nccw. Further information about the survey and analysis can be found in the draft documents: survey_description.wpd, elements.wb3 and fields.wb3 that are supplied with the data set.
