Figure 2. Location of heat-flow measurements, PUPPI deployments, and piston cores in North Pond. The heat-flow values are given next to the location of each penetration. The box in the lower right-hand corner indicates the location of Hole 395A.
Figure 3. Measured and estimated downhole flow rates in the three best documented cases: Holes 395A, 504B, and 857D. Hole 395A data are from Becker et al. (1984), Kopietz et al. (1990), and Morin et al. (1992).
Figure 4. Schematic drawing of pore-water flow and isotherms (°C) below North Pond,
assuming laminar flow at a rate of ~1 m/yr. The variation in heat flow across the pond is shown
along the top of the figure.
