Mohonk Preserve Ground Water Springs Data, 1930 to Present

In a region strongly affected by acid precipitation, the Mohonk Preserve's Daniel Smiley Research Center, has been monitoring the monthly pH and temperature of eight ground springs (Chestnut, Rock, Mohonk, Rhododendron, Mossy Brook Bank, Mossy East Box, Mossy West Box, Rock Rift) on the Preserve dating as far back as 1930 to present day. Monitoring before January 1991 was intermittent and opportunistic but starting in 1991 sampling became more consistent. Monitoring of dissolved oxygen, nitrate concentrations, and conductivity of the springs using a YSI Sonde Professional Plus Instrument began in November 2017.
