Diurnal and seasonal water variations of temperature, pH, redox potential and conductivity in gnammas (weathering pits) : implications for chemical weathering

Abstract

This study describes the main hydrological processes in gnammas and the underlying chemical interactions with the environment. Four gnammas developed in a granite tor from central Spain were chosen for monitoring and studying the dynamics of the gnamma-water system. Parameters monitored were air and water temperature, pH, ORP (redox potential), and conductivity. These measurements describe the system dynamics, without the need for special sampling or other potential interferences under low water volumes. Overflow of water during the winter, when the water is chemically enriched, is an effective mechanism to remove weathering products
