Title
Stream specific conductance and temperature from small watersheds in the Andrews Forest
Abstract
Stream specific conductance and water temperature are measured instantaneously every 5 minutes at most of the gauged watersheds within the H.J. Andrews Experimental Forest (Watersheds 1, 2, 3, 6, 7, 8, 10 and Mack Creek). Data is complementary to stream chemistry measurements from a proportional sampler (CF002) and long-term streamflow measurements (HF004) made at each of these watersheds.
