Quantitative geological data collected from the first operational use of a long coring system is presented. This coring system was used on three scientific cruises in 1987 covering a geographic area extending from Baffin Bay to the Scotian Shelf on the Canadian continental margin. Forty cores were recovered during these cruises. Physical properties, which include index, geotechnical and acoustic data, were obtained on all core samples. In addition, cores were analysed for sedimentology, biostratigraphy and magnetic susceptibility. The large diameter of this corer allows multiple tests to be completed at important subseabed horizons. The scientific results are presented by illustrating core samples collected from the Scotian shelf in Emerald Basin.
