Video-logging through a transparent tube is described as an alternative method for examining in situ the distribution of biogenic structures within the deep layers of heterogeneous sediments in which undisturbed cores are hard to be obtained. The method comprises four successive phases: the installation of transparent tubes into the sediment, the lowering of a video-camera for scanning sediments through the tube walls, the numerical treatment of images for correcting deformations and obtaining… CONTINUE READING
