Oversized Figure

Chapter 25, Figure 1. Foldout showing a seismic transect across the Blake Ridge overlain by symbols indicating direct observation of gas hydrate and indicators of gas hydrate dissociation. In addition, downhole logging measurements, in situ gas concentrations, and pore-water chlorinity concentrations are plotted as lines with depth. Interpretative horizons and zones are inferred from a synthesis of these observations. (PDF)
