摘要
Torque measurements are made by divers with a vane apparatus to a sediment depth of 136 cm in the high-porosity, gassy sediments of Eckernforde Bay. Corrected shear strength values calculated from torque measurements are quite variable in the Eckernforde Bay sediments, varying from less than 0.5 kPa in the top 10 cm of sediment to 4-5 kPa at 136 cm sediment depth. Variability increases markedly below 60 cm sediment depth, probably because of the presence of methane gas bubbles within the sediment fabric.
