Title: Long-term water quality monitoring in the Altamaha, Doboy and Sapelo sounds and the Duplin River near Sapelo Island, Georgia from May 2001 to August 2009
Abstract: Water samples were collected on Georgia Coastal Ecosystems LTER oceanographic monitoring cuirses approximately every three months from May 2001 through December 2006 and monthly from November 2006 to August 2009. Concentrations of dissolved nutrients (ammonium, nitrate+nitrite, phosphate), dissolved organics (DOC, DON, DOP), particulate organic carbon and nitrogen, total suspended sediment, and total particulate iron and phosphorus were measured using standard analytical methods. The concentrations of six elements (calcium, potassium, magnesium, sodium, silicon, and strontium) were also determined occasionally using elemental analysis by inductively coupled plasma mass spectrometry (ICP-MS).
