Field water-quality information along the proposed trans-Alaska pipeline corridor, September 1970 through September 1972

This report presents field water-quality information collected during parts of 1970, 1971, and 1972 along the proposed trans-Alaska pipeline corridor. The data include measurements of water and air temperature, specific conductance, alkalinity, pH, dissolved oxygen, chlorophyll "a," stream discharge, and ice conditions for 69 sites (fig. 1; table 1). At 11 stream sites 24-hour studies were conducted and additional data on barometric pressure, light intensity, percent cloud cover, and wind conditions are presented for these studies (table 2). Seasonal turbidity data are presented in table 3. This information was gathered in connection with studies of the biological characteristics of selected stream sites along the proposed trans-Alaska pipeline corridor. Laboratory data on the inorganic chemical and biological characteristics will appear in future data reports.
