(6.4-cm) cubical sample for directional permeability measurements. The chief requirement was to l~Oduce cut surfaces in a layered soil which were unsmeared anf u x ~ o r n . T h e design was based on three requireme~N;s: (I) c o ~ f i ~ n t s of the soil during the cutting ~ocess, (2) movement of the cutting wire in the direction parallel to the soil layers and (3) small longitudinal vibratory movements of the cutting wire.Auth.

Two acoustical logging devices, the Seisviewer and 3-D Velocity systems can be successfully used in fracture evaluation. The dip and strike of fractures as de~med from the Seimriewer log can be satisfactorily correlated with the core samples from the same hole while the 3-D Velocity log will assist in identifyir~ the fracture as we~l as ~oviding reliable irfo~mation on the elastic propertle~ of the rocks. Experimental data regarding the attenuation of smplltude of both the compresslonal and shear waves across fractures seems to compare satisfactorily with the field results
obtained by 3-D Velocity log and Seisvie~er systems. The hole-to-hole technique with the 3-D Velocity system can be used to investigate fracture planes which are not penetrated by the b~rehole. Selsviewer and 3-D Velocit~ logs will provide "in-situ" informstlon regarding the fractures and the elastic l~'opertles of rocks in slope stability studies as well as other design l~oblems involved wlth subsurface engineerir~.

A device for sampling %he interstitial waters of deep-sea sediments ia-situ has been developed and tested. The s~mgler collects a series of samples over a depth of i. 5 meters in the sediment and thus makes possible the sccurate delineation of chemical gradients existing ~n ~ne pore waters. Results of ss~mpling ur~ertaken in the North Atlantic are presented. Significant ~Ccedients of potassium cation, and calcium dicatio~ were fo~_nd, and betWeeN Ireland and Cape Cod the interstitial solutions were characterized by potasslum depletion and calcium enrichment.
