text: While the SP values are minima, the SP/elevation gradient is still slightly positive (+0.03 mV/m) suggesting that the hydrothermal system on the N rim is strong enough to compensate for the influence of the hydrological zone, characterized on the E and NE by negative SP (with a minimum at -120 mV) and an inverse SP/elevation gradient of -1.07 mV/m.
