Acidity in Polar Ice Cores - North American Acid Rain History Recorded in the Greenland Ice Sheet and the Natural Patterns of Acid and Base Aerosols in Antarctica
pH is a master variable that controls many chemical reactions in nature due to the abundance of acids and bases in the Earth environment. A novel method for continuously measuring pH and acidity in ice cores is applied ...
Cerium in Ice Cores as a Tracer of Mineral Dust
The rare earth element (REE) cerium (Ce) is examined as a potential tracer for mineral dust. Mineral dust trapped in ice cores provides a record of dust levels and atmospheric conditions in the past. Previous studies of ...
A continuous method for measurement of pH and acidity in ice cores
A continuous direct measurement technique has been developed for the accurate determination of pH and acidity in ice cores at monthly to seasonal resolution. A small flow-through bubbling chamber is employed for sample ...
