dc.description.abstractBenthic disturbance is carried out in the Central Indian Basin for environmental impact assessment studies. Geotechnical measurements were made on sediments collected before and after disturbing the top 10-15 cm of the seafloor. Results indicate that the water content of siliceous sediments is high due to high porosity. The comparative studies revealed increase in sediment water content after the disturbance. Shear strength showed large variations with no specific trend due to disturbance; that could affect the bearing capacity of sediments. Significant reductions in the strength values in surface (0-5 cm) sediments from the towed zone of the disturber are observed. Porosity and wet density have not shown any significant change.
