Dissolved Organic Matter spectrofluorometric properties along a mountain to urban gradient in North East Utah

Filtered river water was analyzed with an Aqualog Spectrofluorometer to produce Excitation Emission Matrices (EEMs). Five indices (FI, BIX, HIX, TC, SUVA) were calculated from the EEMs. Dissolved organic carbon and total dissolved nitrogen were measured on a Shimadzu TOC analyzer. Samples were collected in Sep and Nov of 2014 and Nov and Dec of 2015. Further information about the sites and watersheds can be found on the iUTAH website for the GAMUT network observatory http://data.iutahepscor.org/mdf/Data/Gamut_Network
