Precipitation Acidity at the Hubbard Brook Experimental Forest HBEF scientists have measured the pH of precipitation - rain, snow, sleet, etc. - in Watershed 6 since 1965. Watershed 6, as you have learned, is the chemical reference watershed. Examine the graph below.
Go to the next page to look at another short-term precipitation data set. The data used to produce this and the next two graphs were provided by Gene E. Likens with funding from the National Science Foundation and The Andrew W. Mellon Foundation. |
