164 Preliminary Report 164 Preliminary Report Figures Figure 1. Contours are in meters. Shaded region along the Blake Ridge and Carolina Rise indicates the areas where gas hydrate occurrence has been inferred on the basis of BSRs. The profile crosses perpendicular to the topography of the Blake Ridge.
Vertical scale is in seconds of two-way traveltime.
Vertical error bars show sample interval uncertainties, and the box indicates combinations of sample interval uncertainty and age uncertainty. The horizontal bar at the bottom of the figure indicates the range of Amaurolithus amplificus. Triangles indicate measurements made with the Adara tool, squares are WSTP measurements, and circles denote data collected with a prototype probe designed by E. Davis and H. Villinger. The open squares correspond to anomalous temperature measurements obtained within the gas hydrate stability field at Site 994. Errors in temperature are estimated subjectively, based on the quality of the equilibration record and the magnitude of the correction applied to the raw data.
