Geotechnical properties of two deep-sea marine soils from the Labrador Sea
Cores from two deep-sea sites from the Labrador Sea have been extensively studied using various analyses. X-ray techniques provided a continuous profile of bulk densities and an accurate description of the bedding. The soil structure was analyzed by scanning electron microscopy. Detailed identificat...
