The presentation (Fig. 1) gives an overview of how each of these measurements fits together as a function of depth rather than to provide a precise comparison of data.
The single channel seismic depth section USGS 95-1 showing the Site 994-997 transect is the background. On the seismic section three principal features are present: sediment horizon reflections within the upper section, the area of seismic blanking below, and the BSR. Each downhole measurement was graphed, and then scaled to the depth scale on the seismic section. Relative scales for each measurement are given in the legend and as an absolute scale on the seismic section above or below each measurement. Each measurement and their significance are briefly described below. A more detailed description of each measurement and their implications regarding gas hydrate occurrence can be found in the Leg 164 Initial Reports (Paull, Matsumoto, Wallace, et al., 1996).
