Mullaney, J.R., Martin, J.W., and Morrison, J., 2018, Data on nitrogen concentrations and loads for the Connecticut River at Middle Haddam, Connecticut, computed with the use of auto-sampling and continuous measurements of water quality, 2008-14: U.S. Geological Survey data release,


This U.S. Geological Survey data release presents tabular daily data on nitrate plus nitrite nitrogen and total nitrogen loads for the Connecticut River at Middle Haddam, Connecticut, from December 6, 2008, to September 30, 2014. The data release contains total nitrogen concentration estimates at 15-minute intervals from December 2011 to September 2014. The data release also includes tabular information on the total nitrogen loads from the Connecticut River at Thompsonville, Connecticut, from October 1, 2008, to September 30, 2014. Data for each streamgage and constituent include the daily loads and upper and lower 95-percent prediction intervals; the method used in the load calculation for each streamgage is also included in this [...]
