Water stable isotopes for streams and precipitation samples in the HJ Andrews Experimental Forest and Mary's River Watershed, 2014-2018

Water samples have been collected for analysis of water stable isotope (O18/16 and H2/H1) at different locations in the HJ Andrews Experimental Forest and over different periods since 2014 2014 in the HJ Andrews Experimental Forest and in the Mary's River Basin. The database includes: 1) grab samples collected over the mainstream network of the Andrews Forest on three sampling campaigns during baseflow conditions, July-September, 2015, June 2016, and September 2016. In each of the three samplings, the samples were collected at approximately 100-meter intervals in the 2nd to 5th order streams of Cold, Lookout, Mack, and McRae Creeks; 2) water samples collected in the Andrews Forest every 1-3 weeks between 2014 and 2018 in streams (Lookout Creek, Mack Creek, McRae Creek, WS01, WS02, WS07, and WS08) and bulk precipitation from benchmark meteorological stations (PRIMET, MACK, and H15MET); 3) stream and precipitation samples collected in the Andrews Forest at high temporal resolution during discrete storm events at Mack Creek in 2015; and 4) water samples collected every 2-3 weeks between 2014 and 2015 at 24 streams and 3 bulk precipitation collectors in the Marys River basin.
