Title:

Long-term water quality monitoring in the Altamaha River near Doctortown, Georgia from January 2013 to December 2018.

Abstract:

Water samples were collected monthly on the Atlamaha River near Doctortown, Georgia. The samples were anlayzed for dissolved organics (carbon, nitrogen, phosphorus), dissolved nutrients (ammonium, nitrite, nitrate, phosphate, silicate) and particulate carbon and nitrogen. Concentrations of the following were measured using standard analytical methods: dissolved nutrients (phosphate, nitrate+nitrite, ammonium, silicate), dissolved organics (carbon, nitrogen, phosphorus) and particulate carbon and nitrogen
