As a part of its carrying on with application to stimulate greater simple study within the marine atmosphere, the workplace of Naval examine, Ocean technology and expertise department, backed a chain of closed seminar-workshops in 1972-1973. every one seminar centred upon one re seek sector of marine geology that's rather new and short of a severe evaluate and sped up aid. the themes parts selected for the seminars have been: 1. normal gases in marine sediments and their mode of distribution, 2. nephelometry and the optical homes of ocean waters, three. actual and engineering homes of deep-sea sediments, and four. physics of sound in marine sediments. The ambitions of every seminar-workshop have been to deliver into sharper concentration the state-of-the-science inside of every one topic sector, to influence a point of coordination one of the investigators operating inside every one of those components and to supply the sea technology and know-how department assistance for nationwide software aid. This volume.contains lots of the papers awarded on the semi nar at the actual and engineering houses of deep-sea sediments. The seminar was once held at Airlie condominium, Airlie, Virginia on April 24- 27, 1973 and was once prepared and chaired through A. Inderbitzen. The at tendees have been invited from one of the major investigators during this box from either the engineering and medical disciplines. every one attendee was once asked to organize a paper inside of his sector of spe ciality.

The friction component also requires considerable strains for full mobilization (Nacci and Huston. 1970). The effect of the presence of large amounts of biogenic materials on stress-strain behavior has not been investigated nor speculated to any appreCiable degree although it is generally felt that skeletal remains would tend to collapse during high inter-particle stresses. It is likely that organic debris such as large f~agments of diatomaceous material will play a significant role in shear strength behavior and some of the concepts which have evolved for pure clays (clay minerals).

In addition to chemical factors, the physical and mechanical factors such as rate of deposition, kinetics of water, particle size distribution, and concentration of sediment being deposited, influence the spatial arrangement. One of the more important processes which may play an important role in the marine environment, is cementation at particle contacts. Soil properties such as residual strength, and pseudo over-consolidation may be directly related to cementation (Parker, 1972). Loads imposed on a sediment fabric of low permeability create fluid pressure gradients and a resultant loss of fluid from the pores.
