Survey Description


A regional centre-lake bottom sediment survey was conducted in southern Nova Scotia in 1977 and 1978.  Approximately 3400 samples were collected at a density of 1 sample per 7.9 km2 over an area of 27,000 km2.  Samples were collected using a gravity corer or ‘torpedo’ released by the sampler from the float of the helicopter.

Samples were partially air-dried in the field and then oven-dried and disaggregated at Technical University of Nova Scotia.  TUNS analysed the samples for 12 elements by AAS, U by fluorimetry, and F and As by colormetric techniques.  TUNS analysed the samples for 12 elements by AAS, U by fluorimetry, and F and As by colormetric techniques.

The data, including data for samples reanalysed in 1984, are published as follows:

The geographic extent of the survey is defined by the following polygons:

  • Covers all of NTS 20O, P (both Shelburne), 21A (Annapolis Royal) and 21B (Eastport), parts of 11E (Truro), 11F (Canso) and 21H (Amherst) and most of 11D (Halifax), a large part of mainland Nova Scotia.  It is bounded to the northwest by Bay of Fundy and to the southeast by the Atlantic Ocean.  It extends from the city of Yarmouth in the southwest to Canso in the northeast.
