The Sept-Iles area, NW Gulf of St. Lawrence, Eastern Canada (Fig. 1), is ideal to test our hypothesis as it holds two rivers under the same hydro-climatic regime, but one is a natural river. Gulf of St. Lawrence, Quebec, Canada - A Case Study J.B. Henry* RPS Energy, Canada Ltd., Calgary, AB, Canada [email protected] and P.K. Bradley Sky Hunter Exploration Ltd., Calgary, AB, Canada Introduction An offshore exploration program was carried out on two separate blocks in the Gulf of St. Total magnetic field data were acquired every 6 s using a proton precession magnetometer towed m astern of the ship. During initial processing (Watts, ; Watts & Haworth, ), the data. Cite this chapter as: Miller H.G. () Gravity and Magnetic Studies of Crustal Structure in Newfoundland.

  The portion of the Gulf of St. Lawrence which extends from the St. Lawrence platform down to Logan's line is situated between longitudes ' and 67 and latitudes ' and ' N cover- ing an area of 12, km2. The standard 1/63, AM maps obtained from the Geological Survey of Canada were used for digitization purpose. Expected accuracies (at the one sigma level) are: gravity field, 1×10 −5 m s −2 (1 milliGal). 5 cm geoid height; magnetics, scalar field 2 nT, vector to 20 arc seconds (96 microradians), both resolved to less than km. With these more accurate and higher resolution data we will be able to investigate the earth's structure from the crust. The St Lawrence Platform and Appalachian deformation front in the St Lawrence Estuary and adjacent areas (Quebec, Canada): Structural complexity revealed by magnetic and seismic imaging Article. Every year, Fisheries and Oceans Canada conducts a major biological survey aboard the trawler CCGS Teleost, a key source of information on the status of marine resources harvested in the estuary and northern Gulf of St. Lawrence. The main objective of the survey is to estimate the abundance and biomass of commercially important species.

Investigation of the eastern Magdalen Basin, located in the southern Gulf of St. Lawrence (Fig. 1), has revealed an area of intense salt tectonism, above a fault-bounded sub-salt high.   Tectonophysics, () Eisevier Science Publishers B.V., Amsterdam - Printed in The Netherlands A synthesis of the geophysical characteristics of terranes in eastern Canada HUGH G. MILLER Department of Earth Sciences, Memorial University of Newfoundland, St. John's, Nfld. A1B 3X7 (Canada) (Accepted ) Abstract Miller, H.G., Gravity and Magnetic Techniques for Geophysical Exploration Gravity and magnetic exploration techniques are both passive in that they exploit a naturally existing field of the Earth. The measured quantity is the integrated effect of the subsurface. The gravity and magnetic fields are both irrotational vector fields described by potential. DURING and the Dominion Observatory carried out a regional underwater gravity survey in the Gulf of St. Lawrence. The purpose of the survey was to extend the regional gravity coverage of Canada for geodetic and crustal studies.
